If the Z-shaped isomer absorbs ultraviolet light, it will become switch to the C-shaped isomer.

Or at least they were after exposure to ultraviolet light made them switch to the C-isomer.

Switching on drugs with ultraviolet light is not ideal in practice because it can have harmful effects.

Ultraviolet light destroys organic dye molecules over time, leading to color change and fading. The new technology may hold promise for many applications such as for jewelry, automotive interior trim, aviation, signage, colored keypads, wearable and electronic displays.

Now, researchers from MIT and the Federal University of Goias in Brazil have developed a new technique that uses ultraviolet (UV LIGHT to extract man-made pollutants from soil and water.

With the help of nanoparticles and UV LIGHT removal of these toxins could be less expensive and time-consuming than current methods.

and colleagues stumbled upon the idea of using UV LIGHT while they were initially designing photosensitive polymers for drug delivery applications.

Once they came up with a polymer that responded to UV LIGHT, they realized that this did not permeate well through skin

therefore asked ourselves in which infrastructures UV LIGHT was used already, Bertrand told Laboutlook. Knowing that UV radiation is used for removing bacteria from water,

when you shine UV LIGHT on them, the water-loving part is separated from the water-fearing part.

They also found that bright red light counteracted the effect of the ultraviolet light, allowing them to both write and erase."

Photolithography is a standard optical process for transferring micropatterns on to a substrate by exposing specific regions of the photoresist layer to ultraviolet (UV LIGHT.

which protected certain regions of the substrate from the input UV LIGHT. Areas covered by the photomasks remain intact with the base layer

while the areas exposed to the UV LIGHT are washed away, thus creating a micropattern. This technology was limited to a two-dimensional,

1) the areas exposed to UV LIGHT lowered the concentration of oxygen and thus resulted in oxygen diffusion;

Photoresist under UV LIGHT creates radicals which initialize a chemical reaction. These radicals are eliminated with the presence of oxygen

This suggests that the photoresist must be exposed to UV LIGHT for an extended time to completely remove oxygen for a chemical reaction to begin.

While the region affected by the UV LIGHT lowered oxygen concentration, the concentration in the untouched region remained unchanged.

This difference in the concentrations caused a diffusion of oxygen to the region under UV LIGHT.

the diffusion occurs in parallel with the direction of the UV LIGHT. When fast, the diffusion process develops horizontally,

outward from the area affected by the UV LIGHT. Professor Kim and his team proved this phenomenon both empirically and theoretically.
