Abstract: The invention relates to a preparation for the photodynamic control of micro-organisms, said preparation being in a liquid or pasty form and containing 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 said 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 singulet 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.

Abstract: The invention relates to a microorganism reducing device, comprising a radiation device which is provided with a light source, a photosensitive substance which treats the area to be treated and is irradiated by said light source. The aim of said invention is to configure said device in such a way that it is possible to carry out an efficient and controllable treatment by means of operationally low-cost and easily handling apparatus. For this purpose, the inventive device comprises at least one applicator provided with a fibre-optic waveguide. In addition, the applicator and radiation device respectively comprise corresponding connector bodies coupling the applicator and radiation device in such a way that the light from the light source is emitted towards the treated area by means of the fibre-optic waveguide.

Abstract: The invention relates to an apparatus for photodynamic therapy and/or for destroying or reducing microorganisms, comprising an irradiation unit having at least one light source, by means of which a photosensitizer applied to a wound area to be treated is activated by way of irradiation, further comprising a camera for recording images of the wound, which is disposed in the irradiation unit, and a positioning unit, by means of which the irradiation unit can be oriented with respect to the wound area. The invention further relates to a method for operating such an apparatus. On a display for the images is a grid with visual indicia distinguishing fields to be irradiated by means of the light sources.
