Traditional liquid bandages, which contain organic solvents like nitrocellulose, camphor, benzyl alcohol, or ethyl acetate, often cause a stinging sensation, making them unsuitable for use on infants, sensitive areas such as genitalia, or delicate skin. In contrast, a team from the Department of Biochemistry at Chiayi University has developed an innovative hydrogel-based liquid bandage that forms a protective film on wounds without causing irritation. This groundbreaking product recently won a gold medal at the 38th Japan Tokyo International Genius Invention Expo, with promising prospects for commercialization through partnerships with biotech companies.

The 38th Japan Tokyo International Genius Invention Expo was held from May 9 to 10, 2024, at the Tokyo International Forum (TIF). Professors Chen Cheng-Nan and Chang Hsin-Yi from Chiayi University’s Department of Biochemistry showcased their novel liquid bandage at the event, earning high praise and a gold medal for their innovation.

Liquid bandages, commonly referred to as “liquid band-aids” or “medical super glue,” have traditionally been made with components that can cause a painful stinging sensation upon application. This limitation makes them unsuitable for infants, sensitive skin around the eyes and genitals, mucous membranes, and even individuals with conditions like G6PD deficiency.

The new hydrogel liquid bandage, developed by the Chiayi University team, integrates natural green solvents with advanced polymer materials. It quickly forms a protective film over wounds without irritation, making it safe for use on both infants and adults. The bandage can also be applied to sensitive mucous membrane wounds. Once dried, it offers excellent wound protection. Additionally, the bandage is enriched with ginger extract and skin-beneficial probiotics’ secondary metabolites, providing antibacterial and anti-inflammatory properties, alleviating wound pain, and accelerating healing. It has passed skin sensitivity tests and safety checks for heavy metals and plasticizers, ensuring its reliability.

The innovative liquid bandage has already undergone medical device registration and patent applications. It has also been transferred to Chloe Biotech, a spin-off company from Chiayi University supported by Taiwan’s National Science and Technology Council’s entrepreneurial project. This collaboration aims to expedite the product’s commercialization, unlocking significant economic value.

Professor Chen Cheng-Nan emphasized that participating in the Japan Tokyo International Genius Invention Expo was an excellent opportunity to showcase the team’s innovative achievements and technological capabilities. He expressed hope that this success would serve as a driving force for Taiwan and Chiayi University’s development in the global technological innovation arena.
