PREPARATION FOR PHOTODYNAMIC CONTROL OF MICROORGANISMS AND USE OF PREPARATION

摘要

PROBLEM TO BE SOLVED: To provide a preparation for the photodynamic control of micro-organisms.SOLUTION: Said preparation is in a liquid or pasty form and contains a photosensitizer which comprises a dyestuff and produces singlet oxygen when irradiated by means of light. The micro-organisms can be marked by means of the dyestuff. The aim of the invention is to improve the preparation in order to enable an improved photodynamic control. To this end, the preparation contains an active ingredient for amplifying or weakening the oxidative action of the singlet oxygen by chemical manipulation of the dyestuff or the nanoenvironment thereof. In a particular form of embodiment, a rinsing solution is used before the irradiation.
