Poison Probe

摘要

The toxic compound methylmercury often bioac-cumulates in fish tissues, where it can exceed recommended maximum levels for human consumption. There is thus a need for simple screening procedures to rapidly detect methylmercury in samples of fish intended for human consumption. Climent et al. now report such a method, in which the presence of methylmercury triggers the opening of pores in a mesoporous inorganic material by liberating a tethered capping group.
