Transition metal compatibilization of poly(vinylamine) and poly(ethylene imine)

In situ growth of gold nanoparticles on SiO2/lanthanide–polyoxometalates composite spheres: An efficient catalytic and luminescent system

“…In addition, PEI could act as a reductant in the preparation of metal particles. The PEI layers could be widely applied for the assembly of metal nanoparticles because their deposition is both convenient and versatile [23,24]. Therefore, it is interesting for us to assembly Au nanoparticles and luminescent lanthanide-POMs on biocompatible silica particles decorated with PEI layers.…”

Covalent layer‐by‐layer assembly of polyethyleneimine multilayer for antibacterial applications

“…In our Ag loading method, the last step was to immerse the TA/PEI multilayer preloaded with reducing agents into Ag + ion containing solution. As a result, certain Ag + ions was reduced to Ag nanoparticle with zero charge while other Ag + ions just binded with the primary, secondary, and tertiary amines of PEI through electrostatic attractions 35, 38, 40, 55. Moreover, our covalent PEI film likely provided an initial burst release of Ag + which was followed by the sustained release of Ag + from the prolonged oxidation of Ag nanoparticle.…”

Synthesis of Ag-coated polystyrene colloids by an improved surface seeding and shell growth technique

“…These impurities must be removed to ensure that the shell growth mainly occur on the core surface. In our experiment, the PEI that adsorbed on the core surface can bond with Ag + ions [20] and metal nanoparticles [21]. In addition, PEI can also act as a reductant in the preparation of metal nanoparticles [22].…”
