Harnessing the power of microbes, biodesigner and researcher Maca Barrera has developed a revolutionary project called Melwear. The aim is to create a natural sunscreen that protects our bodies from harmful UV radiation.
This project was motivated by the pressing environmental issue of increased UV radiation due to the climate crisis, which causes sunburn, photoaging and cancer. Current sunscreens have a significant negative impact on the marine ecosystem, contributing to coral bleaching and the accumulation of toxic substances.
Melwear is exploring the potential of bacterial melanin as a naturally derived sunscreen with UV-absorbing and antioxidant properties. This innovative material acts as a ‘second skin’ that activates and progressively darkens in response to UV exposure, providing dynamic and tailored protection. The concept involves a specular membrane with encapsulated melanin that becomes active when exposed to UV rays, providing long-lasting and effective protection.
Supported by the Making Lab team at the Francis Crick Institute, this project addresses the critical need for effective photo protection that also protects marine ecosystems.
