Novel Strategies for the Preparation and Functionalization of Noble Metallic and Titanium Dioxide Nanoparticles

Water-soluble, monodisperse AgNPs were synthesized using benzotriazole-maleimide as stabilizer. DNA-AgNP conjugates obtained through Diels-Alder cycloaddition were utilized for DDI of enzyme which retained its activity after the immobilization process. CuNPs in aqueous solutions using ascorbic acid and dopamine-based linkers were prepared. They produced ROS, and could be employed as enzyme mimetics and as catalysts for the degradation of harmful fluorescent dyes and antibiotics.
