Typist’s notes: The narrator is an unidentified male. The images throughout this video are in the form of cartoonlike drawings.

VISUAL: In the centre of the screen on a white background: RMIT University logo. Screen transitions with aqua coloured diagonal stripes filling the screen.

VISUAL: In the centre of the screen on an aqua background is a t-shirt that is white with a red RMIT logo on the chest area and the neck and arm seams are outlined in red. A sun is at the top left of the screen and a shadow stretches from the t-shirt to the bottom right of the screen.

Narrator: Our clothing protects us from the sun ...

VISUAL: In the centre of the screen on a black background is a hooded collegestyle jacket that is red with a small white RMIT logo on the right chest with two white stripes on each arm of the jacket and also white stripes on the bottom of the sleeves and jacket and pocket seams. Rain is falling down from top to bottom of the screen but dry in the area on the screen underneath the jacket.

Narrator: ... the rain ...

VISUAL: Screen transitions with a line spinning through 360 degrees in a clockwise direction. The same red hooded collegestyle jacket is in the centre of the screen but now on a green/grey background with snow flakes slowly falling from the top to bottom of the screen.

Narrator: ... and the cold. And now ...

VISUAL: In the centre of the screen on a red background is a white lab coat with a small RMIT logo on the right chest with two pens in the top left pocket.

Narrator: ... thanks to researchers ...

VISUAL: Same image as before but now an RMIT staff ID swipe card appears underneath the lab coat. The swipe card has RMIT University’s logo at the bottom and a black line across the top. The words NanoBiotechnology Research Lab are gradually written on the black line.

Narrator: ... at RMIT’s NanoBiotechnology Research Lab ...

VISUAL: Same image as before but now seven white microorganisms (all the same shape) move from the surrounding edge of the screen slowly inwards towards the lab coat. As the microorganisms reach the lab coat they are all instantly repelled ie turn 180 degrees and are move spinning away from the lab coat towards and off the screen back to where they came from.

Narrator: ... it could also protect us from potential deadly microorganisms.

VISUAL: Same images as before but now the lab coat moves slightly to the upper centre of screen and the RMIT staff ID swipe card moves to the lower centre of the screen. The red background colour on the screen covers the top twothirds of the screen behind the lab coat and the background for the bottom third of the screen behind the swipe card is aqua coloured.

Narrator: By developing ...

VISUAL: Same images as before ie lab coat and ID swipe card, but now more images are added around the screen. In the bottom left of screen is a pile of four folded white sheets on a lime green square background. On the bottom right of the screen is a bandage roll that unrolls slightly with a bandage fastener beside it on a green square background.

Narrator: ... new fabrics that can kill a range of infectious ...

VISUAL: Same images as before but now more images are added around the screen ie on the middle left of screen is a hospital bed on an orange coloured square background and on the top left of screen is a Bandaid on an aqua coloured square background.

Narrator: ... bacteria, RMIT’s work could be a major breakthrough ...

VISUAL: Same images as before but now two more images are added around the screen ie on the middle right of the screen is a red cross on a white background and beside that a medical mask on a lime green background and then above that in the top right corner on a black square background are about 10 microorganisms (as seen earlier in the video).

Narrator: ... for hospitals, where secondary infections can cause serious complications ...

VISUAL: Same images on screen as before but now on the bottom left corner beside the pile of towels is a white skull and cross bones on a black background.

Narrator: ... and even death.

VISUAL: Same images on screen as before and now the label: E Coli is written over the microorganisms which are at the top right of the screen.

Narrator: E Coli ...

VISUAL: The top right square with the image of the 10 microorganisms with the label of E Coli expands to cover the screen.

Narrator: ... for instance, can be killed ...

VISUAL: Same image as before ie the 10 microorganisms with the label of E Coli. Then in the centre of the screen appears the text: 10 Minutes next to a clock with the hands moving 360 degrees around the clock face. Screen transitions off to the left of screen.

Narrator: ... within 10 minutes of making contact with the fabric ...

VISUAL: Orange dots together in nine groups numbering from 3 to 10 in each group on a black background. They are inside a circle as if looking at it under a microscope lens. The labels: Staphylococcus followed by: (Golden Staph) appears in the centre of the screen over the top of the image of the orange dots in groups.

Narrator: ... and nasties, such as Staphylococcus, better known as Golden Staph, are unable to ...

VISUAL: Same image as before but now the orange dots begin to fall down and off the bottom of the screen.

Narrator: ... stick and grow on the surface of this material.

VISUAL: Screen transitions into three sections: top left corner on an orange background is the image of the hospital bed; bottom left corner on an aqua background is the image of the pile of four folded white sheets; and the whole right side of the screen on a dark green background is an image of a white lab coat.

Narrator: The fabric can be adapted across a variety of medical uses ...

VISUAL: Same image as before but underneath the image of the bed in the top left corner is the label: Bedding.

Narrator: ... including bedding ...

VISUAL: Same image as before but underneath the image of the pile of folded sheets in the bottom right corner is the label: Linen.

Narrator: ... linen ...

VISUAL: Same image as before but underneath the image of the lab coat on the right of screen is the label: Surgical Aprons.

Narrator: ... and surgical aprons allowing for infectionfree environments ...

VISUAL: Screen transitions into two diagonal sections: top left corner image is of 12 Bandaids being placed in four diagonal parallel lines and the label: Bandaids appearing between the Bandaids; and on the bottom right corner of the screen is an image of a person’s arm with a bandage covering the wrist and forearm and the label: Dressings appears below the image of the bandaged arm.

Narrator: ... while Bandaids and dressings that use the fabric can kill bacteria within the wound assisting with faster healing. This protection ...

VISUAL: Screen transitions diagonally off the screen to the top left and to the bottom right. An image of a knight wearing a suit of armour and standing on a pedestal is in the centre of the screen. Sparkles twinkle on the armour in different spots.

Narrator: ... is better than armour for vulnerable patients recovering from serious surgery.

VISUAL: Screen transitions off by a red line moving 360 degrees in a clockwise direction. The red then covers the background of the screen and a red question mark symbol inside a white circle is in the centre of the screen.

Narrator: But how exactly does this work?

VISUAL: Screen split into three sections with different coloured backgrounds and images as follows: four white RMIT lab coats (as seen earlier in the video) on a red background are in a horizontal line at the bottom of the screen; the CSIRO logo on a green background is at the top left corner of screen; and RMIT University’s staff ID swipe card (as seen earlier in video) in the top right corner of the screen. The name: Professor Vipul Bansal appears along the black strip on the swipe card.

Narrator: In collaboration with CSIRO scientists, Professor Vipul Bansal’s RMIT team ...

VISUAL: Same images as before but they now move halfway across to the left of the screen to make way for an orange background that covers the right half of the screen. The image at the centre of this is of a glass bottle containing a clear liquid with three small square pieces of cloth in the liquid. A pair of tweezers reaches into the bottle and pulls out one of the three small squares of cotton cloth from the bottle. The label: Tin Plating appears underneath the bottle.

Narrator: ... discovered that by dipping a cotton cloth into a tinplating solution ...

VISUAL: The previous images of the four lab coats, CSIRO logo and Professor Vipul Bansal’s ID swipe card are now transitioned to the left and off the screen. The image of the Tin Plating liquid in the bottle and the tweezers move across to the left of the screen and now two other bottles containing different coloured liquids appear beside it. The tweezers holding the small square of cotton cloth dip the cloth into the brown solution bottle which is in the centre of the screen and the label: Platinum appears underneath it.

Narrator: ... then a platinum solution ...

VISUAL: The camera pans across to the right. The Tin Plating bottle transitions to the left and off the screen. The Platinum bottle is now on the left of the screen and the tweezers place the small square of cotton cloth into another bottle with a silver liquid which is in the centre of the screen. The cloth sits in the liquid and changes colour from white to a dark silver colour. The label underneath that bottle reads: Silver Ions & Glucose. There is a third empty clear bottle on the right of the screen.

Narrator: ... then a solution containing silver ions and glucose, silver nanoparticles grow onto the fabric giving it a reflective mirrorlike appearance.

VISUAL: The tweezers reach back in the bottle of silver ions and glucose and pick up the small square cloth which has changed now from the dark silver colour to black. The camera pans across to the right, the Platinum bottle transitions to the left and off the screen. The Silver Ions & Glucose bottle is now on the left of the screen and the clear empty bottle is in the centre of the screen. The tweezers holding the black cloth move across to pause above the clear empty bottle and then places the black cloth onto the bottom of the bottle.

Narrator: The final step cements the fabric’s antibacterial properties ...

VISUAL: Same image as before but now an eye dropper filled with a green liquid adds the green liquid into the bottle containing the black small square of cotton cloth, filling the bottle to the top. A label underneath that reads: TCNQ.

Narrator: ... the cloth is dipped into a TCNQ ...

VISUAL: Same image as before but now the eyedropper is removed from the bottle and upwards off the screen. The tweezers reach back into the bottle and lift out the black cotton cloth pausing above the bottle. A label to the right of the bottle reads: Micro Crystal Salt Solution

Narrator: ... micro crystal salt solution ...

VISUAL: Camera zooms in for a close up view of the structure of the cloth being held by the tweezers. The woven structure (thick weaves) appears inside a circle as if looking at it under a microscope lens.

Narrator: ... which transforms the silver nanoparticles ...

VISUAL: Camera zooms in further and image changes into thinner strands but still in a woven basketlike pattern inside the circle of the microscope lens. The label Organic Semiconductors appears at the bottom of the screen but still on the image.

Narrator: ... into organic semiconductors that can ...

VISUAL: Same image as before but now the words Kill Bacteria are added underneath the label Organic Semiconductors.

Narrator: ... kill bacteria. And while this discovery ...

VISUAL: Camera zooms in again and back to the image as seen previously ie of the thick weaving structure inside the circle of the microscope lens.

Narrator: ... is a potential lifesaver ...

VISUAL: Screen splits into two sections. On the left of the screen on a green background is the image of a pair of socks with wavy lines emanating upwards from them to represent a bad odour. On the right of the screen on a blue background is the RMIT white t-shirt (as seen at the beginning of the video) which also has wavy lines emanating upwards from it to, again, represent a bad odour and also perspiration marks underneath each arm sleeve. Also a red head sweatband appears above the tshirt in the location where it would be worn on a person’s head.

Narrator: ... it can also make life a lot more agreeable: eliminating odours in fabrics such as ...

VISUAL: Same image as before and the label: Gym Socks appears underneath the image of the socks.

Narrator: ... smelly gym socks ...

VISUAL: Same image as before and the label: Workout Gear appears underneath the sweat band and tshirt.

Narrator: ... and workout gear.

VISUAL: Screen transitions off to the top of the screen. The image of the person’s bandaged arm (as seen earlier in the video) appears in the centre of the screen and the camera zooms in on the bandage.

Narrator: The next step for researchers is to ...

VISUAL: Camera zooms in to focus on a close-up of the bandage fabric as seen under a microscope ie as seen earlier in the video of the thickly woven fabric in the circle of the microscope lens.

Narrator: ... engineer the fabric’s ...

VISUAL: The image inside the circle of the microscope lens changes to the 10 microorganisms (as seen earlier in the video that were labelled as E Coli) and these are surrounded by white bubbles representing the nanoparticles.

Narrator: ... nanoparticles ...

VISUAL: Same image as before but now the nanoparticles move from the spaces surrounding the microorganisms to now totally covering each of microorganisms.

Narrator: ... so that they are effective against deadly bacteria ...

VISUAL: Camera zooms in to focus on the woven fabric in the circle of the microscope lens (as seen earlier in the video).

Narrator: ... without harming ...

VISUAL: The image of the person’s bandaged arm is at the centre of the screen and the person’s hand lifts up their thumb to make the thumbs up sign.

Narrator: ... human cells.

VISUAL: The image of the bandaged arm making the thumbs up sign moves across to stop on the left third of the screen. The remaining two thirds of the screen are divided into two: the top right corner is the image of a hospital; and the bottom right is the image of an operating theatre with a bed on a raised podium and underneath two operating theatre lamps.

Narrator: This technology can then start to make a difference where it is needed most: in our hospitals and operating theatres.

VISUAL: In the centre of the screen on a white background: RMIT University logo.
