The wound healing gel uses smart tech with a special ingredient to effectively kill bacteria in hard-to-reach places within wounds, providing excellent antibacterial efficacy whilst preventing side effects.

Dr Richter's team is developing a dual treatment using "DDC-Cu", a patented combination made of diethyldithiocarbamate (DDC) and copper ions (Cu2+). Copper is an essential nutrient of Staphylococci, a group of bacteria commonly found on the skin. While they are usually harmless, they can become problematic in surgical settings as they can cause infections. This group of bacteria can form biofilms, helping them develop resistance to antibiotics over time.

It is hypothesised that DDC-Cu is transported into bacteria through copper uptake mechanisms delivering the DDC-Cu like a Trojan Horse. This smart drug delivery approach will kill antibiotic-resistant bacteria by inhibiting essential copper-dependent food pathways, impairing their ability to survive.

DDC-Cu is not only safe to use and effective against biofilms of antimicrobial-resistant Staphylococci, but it also synergistically enhances antibiotic potency, making resistant bacteria susceptible again to antibiotics.
