Determination of Methylmercury in Real Samples Using Organically Capped Mesoporous Inorganic Materials Capable of Signal Amplification

Determination of Methylmercury in Real Samples Using Organically Capped Mesoporous Inorganic Materials Capable of Signal Amplification

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...
