Light-Based Approach Reduces Damage to Healthy Tissues in Cancer Treatment Light-Based Approach Reduces Damage to Healthy Tissues in Cancer Treatment
BOSTON, Aug. 1, 2025 — A technique developed at Northeastern University is able to target two of the deadliest cancer types, melanoma and triple negative breast cancer, with chemotherapy drugs but without the usual associated harms. Both cancers are typically resistant to chemotherapy, said Fleury Augustin Nsole Biteghe, a lecturer in biotechnology, chemistry and chemical biology. But by attaching a light-sensitive drug to a protein called MTf — which appears abundantly in both cancers — and bathing
