Indian-origin team develops novel gel for biomedical research

Mon, May 04, 2015, 12:29 PM
New York, May 4 , 2015: A team of Indian-origin researchers from the Harvard University has developed a novel, truly biocompatible hydrogel that can speed up research and development of several promising applications in tissue engineering.

The new gel can be synthesised using "click chemistry" which is a methodology for the quick and practical synthesis of substances using just a few reliable, chemoselective compounds.

"It is injectable so it can be used to deliver cells or ***** to specific places in the body such as a location that has suffered a wound or has been invaded by a tumour," said associate professor Neel Joshi from the Wyss Institute for Biologically Inspired Engineering at Harvard.

"We are already using it for lots of different things in the laboratory due to how easy it is to synthesise," he added.

Hydrogels can be up to 99 percent water and are similar in composition to human tissues.

They can take on a variety of forms and functions beyond that of contact lenses.

Biomedical engineers have successfully used hydrogels as 3D molecular scaffolds that can be filled with cells or molecules for bodily injection or application in order to release ***** or stimulate tissue regeneration.

Alginate hydrogels -- which are made up of the polysaccharide naturally occurring in brown seaweed -- are just such materials.

Joshi leads a team at the Wyss Institute developing new synthetic biomaterials that mimic naturally-occurring materials.
