The research details the creation of LTG@RL, a specialized light-driven hydrogel designed to prevent cancer from returning after surgery. Scientists discovered that the fatty acid-rich environment at surgical sites causes immune cells to become suppressive, which helps residual tumor cells grow. To combat this, the hydrogel releases a nanomodulator that converts these lipids into toxic peroxides, triggering a specific cell death called ferroptosis in cancer cells. Simultaneously, the treatment uses rapamycin to reprogram immune cells, turning them into active defenders that restore the body’s…
