A Fluorescent Nanosensor Based on Magnetic Silica Nanoparticles as Illicit Drug Vapor Logic Gate

摘要

Herein we report a fluorescent nanosensor base on magnetic silica nanoparticle as illicit drug logic gate. A novel naphthlimide derivative was synthesized (F) , characterized and doped into the magnetic silica nanoparticles (Fe_3O_4@SiO_2/F). It Fluorescence intensity markedly enhanced by adding of metamphetamine.
