Gene therapy has become one of the most discussed techniques in biomedical research in recent years.

Nanoparticle-Based Drug and Gene Delivery for Tumor Targeting

Professor Yoshiki Katayama (Kyushu University, Japan) discusses recent advances in drug delivery systems and strategies that exploit the EPR effect, with a special focus on stimuli-responsive systems based on novel materials.

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.
