Abstract
Reported herein is the development of non-covalent, proximity-induced energy transfer from small-molecule toxicants to organic fluorophores bound in the cavity of γ-cyclodextrin. This energy transfer occurs with exceptional efficiency for a broad range of toxicants in complex biological media, and is largely independent of the spectral overlap between the donor and acceptor. This generally applicable phenomenon has significant potential in the development of new turn-on detection schemes.
摘要
本文报道了非共价、邻近诱导的能量从小分子毒物转移到结合在γ-环糊精腔内的有机荧光团的过程。对于复杂生物介质中的多种毒物，这种能量转移以极高的效率发生，并且在很大程度上与供体和受体之间的光谱重叠无关。这种普遍适用的现象在开发新型开启式检测方案方面具有巨大潜力。
