Giamatrix New Artificial Skin
May 14, 2010 18:01


“Giamatrix”, an innovative bioplastic material, covers injuries or severe burns and cures them, while dissolving. Russian researcher Ramil Rakhmatullin from Orenburg State University invented a new material, based upon polymerized hyaluronic acid, which allows patients to avoid painful dressings. The scientist dreams of growing parts of human organs to replace damaged ones.

“Giamatrix” is made by means of photopolymerization of natural hyaluronic acid. New artificial skin has great bio-engineering properties – elasticity, adhesion, and mechanical strength. Photopolymerization causes formation of lateral links between linear subunits of hyaluronic acid without help of any chemical agents. The biomaterial covers an injury, sticks to it, and helps it cure faster by creating a favourable microenvironment for migration and mitotic activity of cells – developers claim no other artificial skin on the world can do that.

Researchers plan to start commercial production of their innovation and make annually about 150 000 leaves of “Giamatrix” with size of 10x15 cm. Seventy five square centimeters of foreign artificial skin HYAFF, made on the basis of chemically modified hyaluronic acid, cost $135, while 150 square centimeters of “Giamatrix” are expected to cost $40.



The researcher still has to face a challenge – the innovative biomaterial doesn’t have all necessary medical certificates. Optimists hope to get them this year, while pessimists talk about 2011 – a lot of paperwork has left. However, Rakhmatullin already developed “Giamatrix-Light” – peptide complex with same hyaluronic acid, which can be bought in some pharmacies in St. Petersburg, for example. This version of artificial skin was designed specially for beauty industry – cosmetic surgery, dermabrasion, and peeling. Peptides provide normal functioning of cells, restore their activity, regulate immune reactions of cells and stabilize cell metabolism. Being small chemical compounds, peptides reach even deep skin layers, reduce inflammation, and recover skin’s own protective mechanisms. Peptides launch self-regulation processes, which slowly weaken with age and under aggressive environment.

and can be stored for a long time without any special requirements. New biomaterial can be used in combustiology (treating burns with various level of severity), surgery (patients with diabetes, who suffer from diabetic foot; patients with gravitational ulcers, which form when venous blood flow is disturbed; neurodermatitis and psoriasis), otosurgery (surgery of ear drum and auditory ossicle defects), cosmetology (recovery of skin cells after various peeling types and dermabrasion). Creators of this biomaterials hope that many people, who suffer form burns or ulcers, will feel relief. Among buyers of “Giamatrix”, scientist expect to see state hospitals and the Ministry of Emergency. .
