An inverse opal photonic crystal sensor that could specifically detect chloramphenicol (CAP) in a label-free way was introduced in the current research. A colloidal crystal template was first prepared from monodisperse SiO(2) nanospheres. Precursors with different compositions were infused into

Polymethacrylate-based monolith with weak cation exchange functionalities was prepared in capillary column (i.d. 100 μm, o.d. 375 μm) by in situ polymerization of butyl methacrylate, ethylene dimethacrylate and N-methacryloyl-L-glutamic acid in presence of porogens. The porogen mixture included N,N-dimethyl formamide
A new type of redox/pH dual stimuli-responsive poly(methacrylic acid) (PMAA)-based nanohydrogels was prepared from methacrylic acid and N,N-bis(acryloyl)cystamine crosslinker via distillation-precipitation polymerization. The nanohydrogels could be easily degraded into individual linear short chains (M(n) ≈ 1200, M(w)/M(n) < 1.1) in
Glycosaminoglycans (GAGs) take part in numerous biological processes by binding to protein molecules and functionally regulating protein-ligand interactions; therefore, molecular interactions of GAGs have been studied by several methods, including surface plasmon resonance, enzyme-linked immunosorbent assays (ELISAs), and GAG microarrays.

We synthesized 8 polymethacrylate monolithic capillary columns using laurylmethacrylate functional monomer and various cross-linking monomers differing in the polarity and size. The efficiency of monolithic columns for low-molecular compounds significantly improved with increasing number of repeat non-polar methylene groups in
