Recycled Plastic Proves Effective in Killing Drug-Resistant Fungi

Researchers at Singapore's Institute of Bioengineering and Nanotechnology (IBN) and California's IBM Research -- Almaden (IBM) have discovered a new, potentially life-saving application for polyethylene terephthalate (PET), which is widely used to make plastic bottles.

They have successfully converted PET into a non-toxic biocompatible material with superior fungal killing properties. As reported in Nature Communications, their new material proved particularly effective in destroying drug-resistant fungi and fungal biofilm, displaying great potential as an antifungal agent to prevent and treat topical fungus-induced diseases such as skin infections and keratitis.

IBN Executive Director Professor Jackie Y. Ying shared that, "A key focus of IBN's nanomedicine research efforts is the development of novel polymers and materials for more effective treatment and prevention of various diseases. Our latest breakthrough with IBM allows us to specifically target and eradicate drug-resistant and drug-sensitive fungi strains and fungal biofilms, without harming surrounding healthy cells. We hope to eventually apply this technology clinically to help the large number of patients worldwide who suffer from fungal infections."
