Development of new material coatings based on hybrid Au@Ag nanostars and PVDF for biocide applications
The widespread use of antibiotics is generating the appearance of multiresistant microorganisms, which will become one of the most dangerous hazards for
human health in the next years. Physical methods with biocidal properties are appearing as a promising alternative to mitigate this problem. [1, 2, 3]
Here, several versions of silver-coated gold nanostars (Au@Ag NSs) were synthesized through seed-mediated growth processes, generating partially coated
nanostars exhibiting Au tips that protrude from the silver coatings. They exhibit good optical properties tunable in the visible and near IR regions. The
nanoparticles were processed with PVDF polymers through two different methods, in the form of porous or continuous materials. These novel materials
present dual photothermia and release of silver, becoming a promising material as substrate or coating for antibacterial surfaces and devices.
