A wound dressing that guides cells close to the wound has been designed by scientists in Switzerland.
The dressing is made from polydimethylsiloxane and is etched with grooves, which enhance cell polarisatrion, migration speed and directionality.
The dressing makes wound healing faster and may prevent scar tissue forming. The dressing is also non-adhesive and controls cells in a ‘top down’ approach. Unlike current dressing, this one can be removed when the tissue is healed.
