Millions of patients have to live with wounds that do not heal normally, taking months or years to heal.  Their numbers are continually growing, their wounds are complex to assess and continually changing.  This creates an obstacle course for practitioners working in increasingly constrained health care systems and trying to select the right treatment at the right time. 

Io-Cyte exists to provide innovative treatments for healing the wound that can be applied in the patient’s home or doctor’s office.   Research has told us more than ever about the multiple barriers to healing, such as biofilms, local infection and chronic inflammation,  however deciding what is the main obstacle facing a particular wound at any one time is far from straightforward.  Io-Cyte are developing dressings that combat multiple healing barriers at once to give the best chance of forming a healthy wound base for healing.

The company formed in October 2019 when we identified the potential wound-healing benefits from research in a biomaterials laboratory specialising in biocompatible and absorbent fibre materials.
