Alignment of gold nanoparticles using insulin fibrils as a sacrificial biotemplate

摘要

Insulin fibrils were used as a biotemplate for creating gold nanoparticle chains on glass substrates, and then subsequently removed by exposing the samples to a low-pressure plasma, leaving the gold nanoparticles on the glass surface in their template positions.rnMetallic nanoparticles (NPs) exhibit unique optical, chemical, electronic, and magnetic properties that depend on their composition, size, shape, and spatial arrangement. Several methods exist for creating NPs on surfaces, such as deposition, direct synthesis on the surface, and film annealing.
