Colloidal metal nanoparticles dispersed in amphiphilic polymers

Self‐Assembled Nanoreactors

“…200,[231][232][233] Not only does the presence of the polymeric shell around the metal particles aid in the prevention of agglomeration and precipitation, it also improves their processability. The block copolymer micelles can indeed be regarded as nanoreactors, because metal nanoparticles are synthesized inside their interior.…”

“…The nanosize dimensions of the metal particles give rise to a number of intriguing electronic, magnetic, optical, and catalytic properties, which is the result of size quantization effects and the high number of surface atoms as compared to the number of atoms in the bulk of the particle. 202,231 The steps involved in the formation of such metal particles are depicted in Scheme 9.…”

Self-Organization and Morphological Characteristics of the Selenium Containing Nanostructures on the Base of Strong Polyacids

“…It seems that in both cases the same mechanism of adsorption of macromolecules on selenium nanoparticles is realized. So, for ionogenic polymeric matrix (at pH = 3.5 strong polyacids are in ionized state) it is observed electrosteric stabilization stipulated for by electrostatic effects from one side and entropic and osmotic effects from another side [37] appearing due to hydrophobic interactions in aqueous medium between hydrophobic fragments of organic macromolecules and energy saturated surface if selenium nanoparticles.…”

Electrophoretic Separation of Proteins in Capillaries Filled with Poly(ethylene oxide)-stabilized Silver Nanoparticles

“…36 Increases in the concentration of stabilizer will make the NP suspension more stable, favoring the strong NPprotein interactions. The analysis time shows a trend of decrease with addition of PEO till 0.05 g/L, and then it increases with further addition (Fig.…”

“…32 Poly(ethylene oxide) (PEO) is an often-used stabilizer for NP suspension. [33][34][35] PEO molecules attach to the surfaces of the NPs through their hydrophobic regions, while their hydrophilic groups will interact with the polar suspension media, 36 thus providing another improvement in selectivity for protein separation. However, to the best of our knowledge, there is no report on investigating PEO-stabilized silver nanoparticles (PEO-SSNPs) in CE separation of proteins.…”
