Nitric oxide (NO)-releasing xerogel membranes were prepared as coatings for an electrochemical glucose biosensor to allow for enhanced biocompatibility while maintaining adequate response times and sensitivity. Formation of the NO-donor species was found to drastically decrease the permeability of the aminosilane-based xerogels to both hydrogen peroxide and glucose. The addition of poly(vinylpyrrolidone)...
To assess the benefits of nitric oxide (NO)-releasing sol-gels as potential antibacterial coatings for orthopedic devices, medical-grade stainless steel is coated with a sol-gel film of 40% N-aminohexyl-N-aminopropyltrimethoxysilane and 60% isobutyltrimethoxysilane. Upon converting the diamine groups in these films to diazeniumdiolate NO donors, the NO release from the sol-gel-coated stainless steel...
