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

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

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

Journal of chromatography. A, 1274, 44-53 (2013-01-08)
A novel composite imprinted material, on the basis of magnetic carbon nanotubes (MCNTs)-incorporated layer using gatifloxacin as a template, methacrylic acid as a functional monomer, and ethylene glycol dimethacrylate as a cross-linker, was successfully synthesized by a surface imprinting technique.

A monolithic, hydrophilic stir bar coating based upon a copolymer of methacrylic acid and divinylbenzene [poly(MAA-co-DVB)] was synthesised and evaluated as a new polymeric phase for the stir bar sorptive extraction (SBSE) of polar compounds from complex environmental water samples.
