摘要
"Figure Presented" Limited access: Silica nanoparticles functionalized with alcohols and thiols have been used for the chromofluorogenic detection of nerve agent mimics. In the absence of the mimics, the thiol groups (yellow circles) react with squaraine dyes (blue diamonds) and result in the bleaching of the solution. In the presence of the mimics, the squaraine-thiol reaction is inhibited (see picture; red triangle= hydroxy, empty triangles = silicate, blue circle = nitrogen). © 2010 Wiley-VCH Verlag GmbH & Co.
