Controlling the distribution of nanoparticles in hydrogels via interfacial synthesis

Abstract

This article presents an approach to precisely control the localization of nanoparticles in hydrogels via interfacial synthesis with a co-solvent.

Urethane functions can reduce metal salts under hydrothermal conditions: synthesis of noble metal nanoparticles on flexible sponges applied in semi-automated organic reduction

“…We recently reported such a regeneration of AuNPs in sodium alginate hydrogels. 70 Structural macroscopic intactness of the materials does not allow for concluding if the metal NPs remain attached to the support rather than being washed away. It is well conceivable that multiple cycles would decrease the NP load on the PUF support.…”

Synthesis of ultrasmall metal nanoparticles and continuous shells at the liquid/liquid interface in Ouzo emulsions

“…CuS and CdS) 2D thin films. 23 This approach was subsequently used by Gazil et al to cover complex hydrogel structures with a thin metal film, 24 and by Armstrong et al to cover emulsified toluene droplets with metal NPs. 25 However, to the best of our knowledge, it was never used in combination with an Ouzo-type emulsion.…”
