Hybrid microgels

Figure 19.18 Thennosensitive hybrid microgel containing gold nanoparticles. The color changes originate from nanoparticle aggregation induced by the swelling/deswelling of the thermosensitive microgel.

Precipitation polymerization can be used for integration of inorganic NPs into microgel structures. An interesting approach for the preparation of the hybrid microgels is encapsulation of the NPs during precipitation polymerization. To demonstrate the efficiency of this method, LaF3 Eu NPs modified with a mixed... [Pg.20]

Figures 20(a)-20(d) shows TEM images of hybrid microgels containing different amounts of HAp. The HAp needles (aspect ratio 12-15) are located primarily in the microgel shell and their amount inaeases with an increase of HAp content. The incorporation of Vim units into microgel leads to controlled growth of HAp within the miaogel and well-defined hybrid particles can be obtained.

Wu et al. demonstrated that metal nanoparticles can be immobilized in stimuli-responsive microgels, and this system offers the possibilities of external switching and manipulation of sensor devices." The CdS hybrid microgels were synthesized through the in situ formation of CdS QDs in the interior of the copolymer microgel of poly(N-isopropylacrylamide-acrylamide-acrylamidophenylboronic acid) [p(NIPAM-AAm-PBA)]. It was... [Pg.25]

The porous microgel stmcture has been used in present study to deposit hydroxyapatite nanocrystals (HAp NCs). The preparation of hybrid microgels containing HAp NCs is shown in Scheme 1. The first step is addition of Ca " "-ions to the microgel dispersion and the formation of HAp in aqueous phase can be performed by precipitation reaction of calcium and hydrophosphate ions in basic aqueous medium. [Pg.143]
