NANOWIRE SCANNING PROBE MICROSCOPY PROBE FOR MOLECULAR RECOGNITION IMAGING

摘要

A scanning probe microscopy (SPM) probe functionalized for use in molecular recognition imaging comprises a cantilever element, a nanowire, a catalyst nanoparticle, a probe molecule and an elongate, flexible linking molecule. The cantilever element has a crystalline growth surface at one end. The nanowire extends substantially orthogonally from the growth surface. The catalyst nanoparticle is located at the distal end of the nanowire, remote from the growth surface. The linking molecule extends between the catalyst nanoparticle and the probe molecule.
