Self-Assembly of the Dipeptide L-Alanyl-L-Phenylalanine under the Action of Methanol Vapor with the Formation of Micro- and Nanostructures

The mechanism of self-assembly by short-chain peptides (oligopeptides) – the process which their molecules spontaneously form an ordered structure has received much attention recently. Self-assembling phenylalanine oligopeptides have been particular interest due to potential as effective aid in design new functional materials. This paper considers results SPM study on ability L-alanyl-L-phenylalanine self-assemble into a thin film under action methanol vapor. micro- and nanostructures that develop surface amorphous films this dipeptide were characterized. A method for monitoring state using atomic force spectroscopy was proposed. obtained contribute development approaches controlled used produce biocompatible materials environmentally friendly nanodevices would help solve various problems medical, environmental, energy fields.
