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.

Integration of surface-anchored metal-organic frameworks (surMOFs) within hierarchical architectures is necessary for potential sensing, electronic, optical, or separation applications. It is important to understand the fundamentals of film formation for these surMOFs in order to develop strategies for their incorporation

Metal-organic frameworks (MOFs) are extremely porous, crystalline materials with high surface area for potential use in gas storage, sequestration, and separations. Toward incorporation into structures for these applications, this study compares three variations of surface-bound and free-standing HKUST-1 MOF structures:
