Photoactivated, localized drug delivery utilizing visible and infrared light
Light is a powerful pharmacological tool that can be used to selectively activate a photo-reactive drug in a specific location. This method, called photodynamic therapy, has been used successfully as a treatment for a variety of cancers including lung, pancreatic, esophageal, and skin cancers. However, most current photodynamic therapies require ultra-violet light, which has poor tissue penetration depths and can severely damage cells. This technology is a class of ruthenium-based tethers that can bind compounds and release them when exposed to visible or infrared light. It can be used to deliver a variety of biologically active molecules, including neurotransmitters, locally and selectively.
