Applicazioni

Polystyrene-block-polyacrylic acid is a diblock copolymer used for making polymeric micelles/ vesicles (polymersomes) and other encapsulation applications, . This PS-block-PAA copolymer is 10 wt. % PAA; and should form micelles in water in the 100~200 nm range. The polystyrene degree of polymerization (DP) is 275 and the polyacrylic acid DP is 30.

Vesicles are microscopic sacs that enclose a volume with a molecularly thin membrane. The membranes are generally self-directed assemblies of amphiphilic molecules with a dual hydrophilic-hydrophobic character. Biological amphiphiles form vesicles central to cell function and are principally lipids of

Functional Polymers for Biomedical Applications

Wide range of functional polymers for biomedical applications have been synthesized and structurally characterized. Several classes of polymers including biodegradable polymers, hydrophilic & amphiphilic polymers, and stimuli responsive polymers have been prepared using controlled and directed functionalization via "living" polymerization such as RAFT, ionic and ring opening polymerization. Selected polymers have been studied for their structure-properties relationship. "
