Colorimetric-Based Detection of TNT Explosives Using Functionalized Silica Nanoparticles

Colorimetric-Based Detection of TNT Explosives Using Functionalized Silica Nanoparticles

This proof-of-concept study proposes a novel sensing mechanism for selective and label-free detection of 2,4,6-trinitrotoluene (TNT). It is realized by surface chemistry functionalization of silica nanoparticles (NPs) with 3-aminopropyl-triethoxysilane (APTES). The primary amine anchored to the surf...
