bioluminescence resonant energy transfer
Multi-Component SwitchBioluminescence resonant energy transfer (BRET) is a multi-component light-activation strategy that uses bioluminescence to induce photochemical activation for photodynamic therapy. In the cited 2015 cancer study, BRET-driven therapy produced cytotoxicity comparable to external red laser irradiation and was applied against deep-tissue tumors, metastases, and tumor-bearing lymph nodes.
