A senolytic strategy integrating multiple technologies delays aging

Cellular senesence is believed to be a driver of aging. We designed and synthesized a photosensitive prodrug that destroys senescent cells by integrating multiple technologies that combine biomarker guidance with a fluorescence tag, target-site anchoring and photodynamic therapy, providing a strategy for monitoring and specifically eliminating senescent cells to regulate aging.
