Patent number: 11135445Abstract: A problem of incomplete inhibition of harmful cells/bacteria and short duration of time, after the photodynamic treatment, during which such cells may re-grow, is solved by exposing the target bacteria with a multi-component photosensitizer material formed by adding a predetermined potentiating chemical to a conventional single-component photosensitizer at the target, prior to irradiating the target with light. The multi-component photosensitizer is effectuated by forming a mix of the two chemical compositions or by sequential exposure of the bacteria to a single-component photosensitizer and the potentiating chemical of choice.Type: GrantFiled: February 15, 2019Date of Patent: October 5, 2021Assignee: The General Hospital CorporationInventors: Daniela Vecchio, Michael R.
