A fast method for the determination of lead in honey samples using stabilizer-free silver nanoparticles
(2018-01-15)
A sensitive, rapid and robust method based on the use of stabilizer-free silver nanoparticles was developed for lead detection in honey. Silver nanoparticles were synthesized without the presence of any stabilizers using ...
Preparation and antibacterial activity of silver nanoparticles impregnated in bacterial cellulose
(Associação Brasileira de Polímeros, 2010-01-01)
A simple method was developed to load a large amount of silver nanoparticles into bacterial cellulose (BC) produced by Gluconacetobacter xylinus in a controlled manner. Due to the high electron-rich oxygen density in the ...
