For decades, photodynamic therapy has promised precision in treating skin cancer, yet the treatment has been quietly undermined by a fundamental mismatch: the drug and the light it requires rarely reach the same depth at the same time. Researchers from Texas A&M University and the University of São Paulo have now proposed a quiet but consequential answer — dissolving microneedles that not only carry the therapeutic drug deeper into tissue, but reshape how light itself travels through the skin. In doing so, they have turned a passive delivery tool into an active participant in the physics of he
