Bioreducible polycations, which possess disulfide linkages in the backbone, have appeared as promising gene delivery carriers due to their high stability in extracellular physiological condition and bioreduction-triggered release of genetic materials, as well as reduced cytotoxicity because intracellular cytosol is

We introduce a chromatography method for purification of large proteins and viruses that works by capturing them at a non-reactive hydrophilic surface by their mutual steric exclusion of polyethylene glycol (PEG). No direct chemical interaction between the surface and the

The use of a carboxylate-functionalized graft copolymer (PGTDC-COOH) based on titanium dioxide-densified cellulose (TDC) for the removal and recovery of thorium(IV) [Th(IV)] from industrial wastewater is reported in this paper. Infrared spectroscopy and X-ray diffractometer were used to characterize the

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.

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
