Thermal Barrier Coating Analysis of Remaining Life and Contaminant Composition
A novel inorganic nanocomposite material,
called BOA, which has
the form of small building blocks composed of gold nanoparticles embedded
in a polyoxoborate matrix, is presented. It is demonstrated that cotton
wool decorated with the BOA nanocomposite displays strong antibacterial
activity toward both Gram-positive and -negative bacteria strains.
Importantly, the modified cotton does not release any toxic substances,
and the bacteria are killed upon contact with the fibers coated with
the BOA. Toxicity tests show that the nanocomposite–in spite
of its antiseptic properties–is harmless for mammalian cells.
The presented method of surface modification utilizes mild, environmentally
friendly fabrication conditions. Thus, it offers a facile approach
to obtain durable nontoxic antiseptic coatings for biomedical applications
