Gold nanoparticle integrated artificial nanochannels for label-free detection of peroxynitrite†
Abstract
A label-free method for rapid and highly sensitive detection of peroxynitrite (ONOO−) was proposed by employing well-designed N-(4-aminobutyl)-N-ethylisoluminol (ABEI) capped AuNP integrated artificial nanochannels. This work paves a new pathway to develop a versatile platform for the detection of different biological small molecules and reactive species.
