Abstract

Abstract: Mesoporous silica nanoparticles loaded with rhodamine B and capped with a bisphenol A aptamer were used for the selective and sensitive detection of this lethal chemical. The pores of the nanoparticles are selectively opened in the presence of bisphenol A (through its selective coordination with the aptamer) with subsequent rhodamine B delivery. With this capped material a limit of detection as low as 3.5 μm of bisphenol A was measured. Abstract : A new hybrid aptamer‐capped mesoporous silica material has been developed for the selective and sensitive detection of Bisphenol A in water.
