Graphical Abstract

Thumbnail image of graphical abstract

The affinity of methylmercury towards capping leuko-squaraine groups (see picture, white) induces the opening of the pores of a capped mesoporous hybrid material and the release of entrapped safranine dyes (orange), thus allowing the selective optical detection of methylmercury in complex biological samples.
