Fundamentals and applications of acrylamide based microgels and their hybrids: a review

“…The most common method used for synthesis of P(NIPAM-Am)/ P(NIPAm-Am-IM) microgels is free radical precipitation polymerization. 13 Potassium per sulfate (KPS), 12 ammonium per sulfate (APS) 13 or azodiisobutyronitrile (AiBN) 8 have been reported as initiators in this method of polymerization using sodium dodecyl sulfate (SDS) as emulsier. In this methodology, NIPAM (monomer), Am (comonomer), additional ionic monomer (if any), MBAAm (crosslinker) and SDS (surfactant) are dissolved in water.…”

“…1 Poly(N-isopropylacrylamide) [P(NIPAM)] is the most common temperature responsive polymer microgel system and its VPTT in aqueous medium is 32 C. 7 When NIPAM is copolymerized with Am, the hydrophilicity of the resultant polymeric network is increased and VPTT of the microgel system is shied to higher temperature because Am units have more affinity towards water molecules as compared to NIPAM and it is difficult to remove water content from polymeric network made of both NIPAM and Am as compared to that made of NIPAM only. 8 Presently, these microgels are being largely used in bio-sensing, 9,10 drug delivery, 11,12 catalysis 13 and optical transduction. 14,15 These microgels are the most promising responsive polymers that remain intact in both swollen and de-swollen states.…”

A facile and green method for synthesis of rGO@SiO2@FeOOH@Ag nanocomposite as efficient surface enhanced Raman scattering (SERS) platforms

“…Surface-enhanced Raman spectroscopy (SERS) is thought to be a promising technique for the trace detection and analysis of organic colorants in food due to its good sensitivity and exceptional spectral selectivity [1][2][3][4][5][6][7][8]. However, as SERS substrates, the traditional noble metal materials cannot meet all of the requirements such as sensitivity and selectivity.…”

“…Hence, considerable efforts have been made toward the development of novel SERS materials. Recently, it has been found that the formed heterointerfaces of composites based on graphene (or graphene oxide (GO)) are shown to have higher performance compared to the individual components [4][5][6][7][8]. Despite many advances in this field, it is still a challenge to exploit new materials that can improve the selectivity and dispersion of graphene-based hybrid materials.…”
