Influence of laser radiation on carbon nanotubes for the formation of frame materials in bioelectronics

Single-walled carbon nanotubes (SWCNT) nanoframes have been created in the form of structured films on a silicon substrate as well bulk biopolymers albumin, collagen, and chitosan. Biopolymers were required to create multilayer, electrically conductive bioelectronic structures for reconstructing layers heart. For this, laser setup was used based pulsed fiber ytterbium with wavelength 1064 nm scanning system. Liquid dispersions SWCNT ethanol aqueous applied onto by layer spraying. Then they irradiated radiation. The effect binding SWCNTs their bundles each other under action radiation is demonstrated. Using SEM TEM, formation "T", "X" "Y" shaped joints mechanical characteristics improved. hardness nanoframe after exposure increases more than 6 times compared original film. specific electrical conductivity 7 times. biopolymer matrices varies range 0.6 - 12.4 S/m, depending type biopolymer. These values exceed heart myocardium. highest roughness shown lower chitosan SWCNT, smallest upper albumin structure. confocal microscopy, possibility cellular structure an dispersion has structure, from promoted better vital functions cells cardiomyocytes.
