Pusan National University Develops Injectable Microgels for Targeted Keloid Radiotherapy

Injectable hyaluronic acid microgels offer a promising new strategy for targeted, minimally invasive keloid radiotherapy

BUSAN, South Korea, Aug. 27, 2026 /PRNewswire/ -- Researchers in Korea are developing a new approach to localized brachytherapy that could improve the treatment of keloid scars. The strategy uses injectable, biodegradable hyaluronic acid microgels that act as tiny radiation reservoirs within target tissue. By combining rapid radiolabeling with localized delivery, the platform aims to overcome limitations of conventional radiation treatment while offering greater flexibility and precision. The study highlights a promising step toward targeted, minimally invasive microbrachytherapy.
