Molecular interactions between sunscreen and human skin, and identification of factors leading to sunscreen removal

Suncayr is a company based out of Waterloo, Ontario that is using nanotechnology to develop uniquepreventive measures to avoid the common problems associated with over-exposure to ultraviolet radiation.Suncayr utilize color changing nanotechnology that indicates when the effectiveness of the applied sunscreen isdiminishing, notifying by color change and indicating the time for sun screen reapplication. A crucial part ofthis technology is the ability of Suncayr's patch to imitate the interaction of human skin with sunscreen, so itwill be removed at comparable rates as it is from human skin during different activities and if not enoughsunscreen is applied to provide appropriate UV protection.While Suncayr was able to engineer a proprietary technology that is functional in most scenarios, insufficientaccuracy was observed under certain circumstances. To identify and overcome these challenges, anunderstanding of the interactions and processes on a molecular level as well as in the domain of surfaceinteractions will be provided by the research of the Taylor group at the University of Toronto. The Taylorlaboratory has extensive experience with the synthesis and characterization of bio-polymers and non-covalenthost-guest interactions. Along with this unique set of expertise, the Taylor laboratory has access to aworld-class analytical department for structure and physical property characterization in solution and onsurfaces.
