The article presents the research results of the material structure intended to replace defects in biological tissues. The material is a three-layer composite obtained from aqueous dispersions of organic components - albumin, collagen and chitosan succinate, connected to a formed inorganic porous matrix, obtained under the influence of radiation from an ytterbium laser with a wavelength of 1064 nm on single-wall carbon nanotubes. To study the binding of the material components to the carbon matrix, the morphology of the resulting layers and the structural parameters of the composite scaffold the methods of vibrational spectroscopy (infrared spectroscopy and Raman spectroscopy), confocal microscopy and SEM were used. It has been established that during the action of laser radiation on aqueous dispersions there is no destruction of the organic components structure. The SEM study indicates the presence on the sample surface of globules with a size of 10-50 microns, formed from nanotubes with matrix materials. The presence of pores in the composite scaffold and their dimensions suggest the possible precipitation and proliferation of the cellular component. [ABSTRACT FROM AUTHOR] |
