Uptake of anionic gold nanoparticles by cationic microgel particles in dispersion: The effect of pH

Symmetric and asymmetric adsorption of pH-responsive gold nanoparticles onto microgel particles and dispersion characterisation

“…Davies and Vincent recently reported on the interaction between AuNP and poly(2-vinylpyridine) microgel particles [35]. They found that there was a high affinity adsorption of AuNP onto the microgel network and maximum adsorbed amounts into swollen microgel particles were in the region 1.5 g gold per g microgel.…”

The interaction between multi-charged organic salts and poly(vinylpyridine) microgel particles

“…The uptake of negatively charged gold nanoparticles into PVP microgels was investigated by Davies and Vincent [20]. It is found that adsorption of Au nanoparticles onto the surface of collapsed microgel particles (pH 6) has little effect on the particle size or structure except for a reversal in surface charge.…”

Redispersible dried hydroxyapatite particles with grafted pH-sensitivity polymer brushes of poly(styrene-co-4-vinylpyridine)

“…Recently, stimuli-responsive hybrid particles had raised great interests in a wide range of fields, for example, microfluidic devices [6][7][8], assembly of nanoparticles [9], chemical gates [10][11][12] and responsive colloids [13][14][15][16][17][18][19][20][21][22][23][24]. Surface modification of nanoparticles with a stimuli-responsive shell had been explored to investigate the reversible response of nanoparticles to altering external stimuli/ signals [13,14], such as pH value [15][16][17][18], temperature [19][20][21][22] and light [23][24][25].…”
