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

The magnetic-targeting stimuli-responsive hollow polymeric microspheres show unique performance as the intelligent carriers for the site specific controlled delivery of drugs or genes. In the work, the well-defied dual-responsive double-walled hollow microspheres with movable magnetic cores were prepared from the
