Polymer/inorganic hybrids containing silver nanoparticles and their activity in the disinfection of fish aquariums/ponds

A grafted polymer/inorganic hybrid combining the properties of silica nanoparticles (R av  = 7.7 nm) and polyacrylamide (SiO 2 -g-PAAm) was synthesized, characterized and used as a matrix for in situ synthesis of silver nanoparticles (AgNPs). In the "core"-"corona" hybrid nanostr...

Description
Summary:A grafted polymer/inorganic hybrid combining the properties of silica nanoparticles (R av  = 7.7 nm) and polyacrylamide (SiO 2 -g-PAAm) was synthesized, characterized and used as a matrix for in situ synthesis of silver nanoparticles (AgNPs). In the "core"-"corona" hybrid nanostructures, PAAm grafts were additionally bonded to the silica surface by H-bonds. The reduction of Ag + -ions in SiO 2 -g-PAAm solutions occurred in PAAm "coronas" with a high rate and yield. This led to the formation of spherical AgNPs of 3-9 nm in size in swollen hybrid nanostructures. Various aspects of the possible use of the AgNPs/SiO 2 -g-PAAm composition for disinfecting fish aquariums/ponds, including biological risks, were studied.
