WitrynaThe self-assembly process has been shown to produce nanofibers with diameters well below 1,000 nm, with a distribution of 5–25 nm [64]. One common method of self-assembly is to first synthesize an amino-acid sequence and then chemically attach an alkyl chain to the oligopeptide, a peptide chain of 2–20 amino acids in length. WitrynaMetallic nanoparticles that absorb and concentrate light are leading to greater efficiencies in nanophotonic devices. By confining gold nanorods (Au NRs) in a polymer film, we can control their spacing and orientation and, in turn, the absorption and polarization characteristics of the nanocomposite. In this study, we systematically increase the …
