New bandage technology will heal persistent wounds — bedsores and other uclers — faster. The bandages are lined with the injured person's own cultured skin cells, which stimulates growth.
The key to the technique is a coating which cells can attach to and grow on, but which releases the cells after the disc is applied to the wound. The CellTran team has adapted the process used to coat the inside of drinks cartons to deposit a thin film of an acrylic acid polymer onto their discs. The polymer remains intact in a growth medium but dissolves when applied to wounds.
