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.

suncair是一家位于安大略省滑铁卢的公司，该公司正在利用纳米技术开发独特的预防措施，以避免与过度暴露于紫外线辐射有关的常见问题。Suncayr利用变色纳米技术来指示所涂防晒霜的效果何时减弱，通过颜色变化来通知并指示重新涂抹防晒霜的时间。这项技术的一个关键部分是Suncayr的贴片能够模仿人类皮肤与防晒霜的相互作用，因此在不同的活动中，如果没有足够的防晒霜来提供适当的紫外线保护，它将以相当的速度从人类皮肤上去除。虽然Suncayr能够设计出一种专利技术，在大多数情况下都能发挥作用，但在某些情况下，人们发现它的准确性不够。为了识别和克服这些挑战，多伦多大学泰勒小组的研究将提供分子水平上以及表面相互作用领域的相互作用和过程的理解。泰勒实验室在生物聚合物和非共价宿主-客体相互作用的合成和表征方面拥有丰富的经验。除了这一独特的专业知识，泰勒实验室还拥有世界一流的分析部门，用于溶液和表面的结构和物理特性表征。
