Description

General description

16-Mercaptohexadecanoic acid (MHA) is a long chained alkanethiol which forms self-assembled monolayers (SAMs) on a variety of surfaces.

Application

MHA forms SAMs on gold dipyramids which can be used in the fabrication of nanoresonators for shell-isolated nanoparticle enhanced raman spectroscopy (SHINERS). It can also be used to surface modify gold electrodes that can be used for sensitive detection of clozapine. Gold surfaces can be self-assembled with MHA by polymer pen lithography (PPL) which can be potentially used in bioengineering.
