Researchers at EMPA, the Swiss Federal Laboratories for Material Science and Technology have developed a healing foam designed to promote scar free healing.
Project ‘Scaravoid’ led by Markus Rottmar of the Biointerfaces laboratory, has been set up to understand why wound healing can be some problematic and complicated for patients which can then lead to extended time spent in hospitals.
“Wound Healing Sped up Thanks to Curry Power“
The foam is made from poly-4-hydroxybutyrate (P4HB) that acts as an energy storage material that is broken down when needed by organisms. P4HB has a structure that is strong and offers elasticity and is able to be broken down in the human body.
The Polymer is expanded in a high pressure reactor with a varying temperature and pressure to fine tune the pore size of the foam. Curcumin (Compound found in the root turmeric and a common ingredient used in curry) is known for its anti-inflammatory properties and is added to P4HB. The curcumin controls the behaviours and function of the fibroblast cells within the foam.
“Whilst traditional wound treatments target individual factors (oxygen supply and moisture regulation), our foam creates a scaffold that allows our body’s repair system to deposit cells that help to clean the wound, and encourage the growth of new tissue. “ explains Markus.
The behaviour of the foam is currently being studies but eh team, targeting the healing of burns and large wounds, and will soon embark on clinical trials.See all the latest jobs in Service Engineering
