New organic-inorganic polymer composite materials with chalcogenide (As2S3 and S) and metal nanocarriers (silver nanoparticles bonded to their surfaces and gold nanoparticles immobilized in the middle of the matrix), as well as new Nafion-based composite membranes and modified by doping of TiO2 nanoparticles with sulfur are synthesized and structural-morphological characteristics of the synthesized structures are investigated. Modification of TiO2-NPs with sulfur with a final content of 2.955 wt.% substantially improves such operational parameters of bio-nanoelectrodes as the sensitivity and apparent value of KM compared to control bioelectrodes without TiO2-NPs or using bio-nanoelectrodes AEROXIDE® TiO2 P25 nanoparticles. At the same time, the critical dependence of the effective electrical conductivity of the bio-nanocomposite and its good biocompatibility on the amount of sulfur in TiO2-NPs samples should be noted. Thus, for bio-nanoelectrodes using TiO2S0.5 (where the sulfur content was lower and corresponded to 2.306 wt.%) and for bio-nanoelectrodes based on TiO2S1.5 (with high sulfur content – 5.903 wt.%), all operating parameters are significantly reduced, compared to control bioelectrodes or bio-nanoelectrodes based on commercial AEROXIDE® TiO2 P25 nanoparticles. The discovery of the phenomenon of the dependence of the efficiency of the use of TiO2-NPs in biosensorics on the degree of their modification by sulfur requires more thorough research in the future.
