General description

All polyethylene imine polymers are hydrophilic and may contain approx. 30% hydrated water.

Application

Poly(vinyl acetate) is commonly used in biomedical applications. The end group functionality contains a cyanomethyl group; and the RAFT agent diphenylcarbamodithioate which will allow for additional polymerization to generate a diblock copolymer. This RAFT agent is well-suited for vinyl acetates and vinyl benzoate

The relatively high transfection efficiency of polyethylenimine (PEI) vectors has been hypothesized to be due to their ability to avoid trafficking to degradative lysosomes. According to the proton sponge hypothesis, the buffering capacity of PEI leads to osmotic swelling and

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. "

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
