<p style="font-size: 14px;line-height:24px;margin-bottom:15px;align:justify;">Nowadays, exposition to harmful UV rays has led to an ever growing number of skin cancer cases, among other sun-related diseases. While efficient sunscreens do exist, we do not always think it necessary or forget to reapply it as often as we should. With our project called BactaSun, we propose to design a biobadge which would detect excessive UV exposure and therefore warn us to seek sun protection should it become necessary.</p>

Only photocaged tyrosine will be available in the media, and linked to a specific tRNA. The reporter protein will be synthetise but in the wrong conformation due to the cage presence. Once the bacterium is exposed to direct sunlight, the cage will be cleaved, inducing the good conformation of the protein and its coloration.</p>

Under these circumstances, we already have been asked to lead panels and participate in debates and discussions. We hope to associate the UCLouvain iGEM project with many more initiative of this kind in the future.</p>

iGEM UCLouvain Team
the project BactaSun

Although melanoma accounts for less than 1% of skin cancer cases, they are responsible for the vast majority of skin cancer deaths. More than 80% of melanomas are caused by the exposure to ultraviolet (UV) radiation from the sun.

Our project: BactaSun, a bio-badge changing color when exposed to sunlight.

Global issue

Over the last years, our exposition to UV rays has increased and scientists noticed an upward trend in the risks of developing skin cancers.
Protection exists

Although we can protect ourselves against this health hazard, we cannot feel the UV rays and when sunburns appear, it is already too late.

Badge design

Hence, we have designed a wearable UV-sensitive badge to help warning people on their level of exposure anytime and anywhere. The badge turns red when exposed to a certain level of sunlight.

Culture design

This badge contains a liquid cell culture. The bacterial cells are engineered o produce a red fluorescent protein, which is only developed when. They only produce it when the badge is exposed to UV rays, thanks to a photocaged amino acid.
