商品

Biomaterials science integrates smart materials into biological research, requiring a deep understanding of biological systems.

The present publication focuses on synthesis and characterization of nanothick, chemically grafted polymer films (polymer brushes) on various inorganic and polymeric substrates.

Microparticles in drug delivery: Study on controlling chitosan microparticle size and distribution, exploring encapsulation of BSA and TPP cross-linker.

Poly(N-isopropylacrylamide), or PNIPAM, is a stimuli-responsive polymer that responds to changes in pH and temperature and has a LCST around 32 C.
