A new silica-gel nanospheres (SiO(2)NPs) composition was formulated, followed by biochemical surface functionalization to examine its potential in urea biosensor development. The SiO(2)NPs were basically synthesized based on sol-gel chemistry using a modified Stober method. The SiO(2)NPs surfaces we...
