Many types of cell-separation methods have been studied and developed. However, these methods are expensive, cannot be operated continuously on a large scale, and are troublesome. The purpose of our study is to develop a novel cell separation method that can capture or enrich a specific cell type continuously and in high yield and that can be operated easily and quickly in clinical settings. We...

A bead-and-spring model has been used to simulate the behavior of thermoresponsive asymmetric diblock amphiphilic copolymers with aid of Monte Carlo simulations. The alteration of the thermodynamic conditions was mimicked by using a Lennard-Jones potential, which was related to the measured temperatures by comparison with experimental data for aqueous solutions of two sets of diblock copolymers...

The synthesis, characterization and property evaluation of drug-loaded polymer-coated magnetic nanoparticles (MNPs) relevant to multimodal cancer therapy has been studied. The hyperthermia and controlled drug release characteristics of these particles was examined. Magnetite (Fe(3)O(4))-poly-n-(isopropylacrylamide) (PNIPAM) composite MNPs were synthesized in a core-shell morphology by dispersio...

BACKGROUND The development of tissue engineering scaffolds for gene delivery has the potential to enhance gene transfer efficiency and safety via controlled temporal and spatial delivery. Lentiviral delivery can be carried out using the natural biopolymer thermoresponsive gel, chitosan/β-glycerol phosphate (β-GP) as a carrier. METHODS Three chitosan/β-GP scaffolds were prepared with varying c...

Critical limb ischaemia (CLI) is a debilitating ischaemic disease caused by vascular occlusion. Pro-angiogenic therapeutics have the potential to produce collateral vasculature, delaying or negating the need for amputation or invasive revascularisation. Thermoresponsive hydrogels can provide an in situ depot for the sustained release of drugs and provide protection and cohesion for encapsulated...

Synthetic macromolecules that can bind and co-assemble with proteins are important for the future development of biohybrid materials. Active systems are further required to create materials that can respond and change their behavior in response to external stimuli. Here we report that stimuli-responsive linear-branched diblock copolymers consisting of a cationic multivalent dendron with a linea...
