In this study, poly(N-isopropylmethacrylamide-co-methacrylic acid) microgels prepared by free radical precipitation polymerization were used as micro-reactors for the synthesis and stabilization of silver nanoparticles. UV-Visible spectroscopy, Transmission Electron Microscopy and Fourier-transform infrared spectroscopy were used to characterize both pure and

Journal of molecular recognition : JMR, 25(2), 69-73 (2012-02-01)
A series of molecular dynamics simulations of prepolymerization mixtures for phenylalanine anilide imprinted co-(ethylene glycol dimethacrylate-methacrylic acid) molecularly imprinted polymers have been employed to investigate the mechanistic basis for template selective recognition in these systems. This has provided new insights

Exudate analysis indicated that both hydroxamated methacrylic acid-based (HX-MAA) and methacrylic acid-based (MAA) beads without hydroxamation, implanted in an air pouch with gelatin discs, elicited similar biological responses, with both resulting in high cell counts and chemokine (MCP3) levels, relative

Amino acids, 43(5), 2113-2124 (2012-04-25)
Molecularly imprinted polymers (MIP) for histamine using methacrylic acid were developed and recognition mechanisms were thoroughly characterized for the first time in this study. The binding affinity of imprinted polymer with structurally related compounds was studied in organic and aqueous
