目前市售的用于防晒制剂中的紫外线（UV）过滤剂存在几个缺点，即有害的人体和生态毒性效应。由于这些缺点，目前的研究兴趣是识别和设计新的UV过滤器。近年来探索的一种方法是利用自然作为灵感，这是本次审查的重点。植物和微生物都已经适应了合成自己的光保护分子，以保护它们的DNA免受潜在有害的紫外线辐射。一个分子被光激发后的弛豫机制可以通过几种技术来解释，其中最感兴趣的是超快光谱和计算方法。在文献中，这两种技术都已在植物和微生物启发的紫外线过滤器上实施，以更好地了解它们在自然界中的光保护作用。本文旨在探讨这两种自然紫外线过滤剂的研究结果，以期指导未来的防晒霜设计。
There are several drawbacks with the current commercially available ultraviolet (UV) filters used in sunscreen formulations, namely deleterious human and ecotoxic effects. As a result of the drawbacks, a current research interest is in identifying and designing new UV filters. One approach that has been explored in recent years is to use nature as inspiration, which is the focus of this review. Both plants and microorganisms have adapted to synthesize their own photoprotective molecules to guard their DNA from potentially harmful UV radiation. The relaxation mechanism of a molecule after it has been photoexcited can be unravelled by several techniques, the ones of most interest for this review being ultrafast spectroscopy and computational methods. Within the literature, both techniques have been implemented on plant-, and microbial-inspired UV filters to better understand their photoprotective roles in nature. This review aims to explore these findings for both families of nature-inspired UV filters in the hope of guiding the future design of sunscreens.
