Abstract

A new lignin modified hybrid microsphere, comprising poly(styrene-co- acrylic acid) core and magnetite (Fe₃O₄)/Au nanoparticle (NP) shell, was proposed here for the selective and highly sensitive detection and removal of 2,4,6-trinitrotoluene (TNT) explosives based on surface enhanced Raman scattering (SERS) and electrochemical detection methods. The presence of lignin and the highly packed layer of Fe₃O₄/AuNPs as a magnetic collector and metal enhancer for SERS signals allowed for the detection of TNT below 1 pM.
