A photosensitizer formulation can be disposed on or in a mesh; net; netting; screen; curtain of strands, fibers, or monofilaments; substrate, personal protective gear, mask, or any other suitable object. The photosensitizer formulation, when in contact with molecular oxygen and activated by light or ultrasound, produces microbicidal singlet oxygen. A variety of different arrangements and applications are described. For example, an air flow device may also be included to generate a flow of air through or over the photosensitizer formulation. A fluorescent formulation may be included to monitor photobleaching. The photosensitizer formulation may be disposed in a concentration gradient to generate antigenic particles by damaging or destroying microbes.

The present invention is directed to chitosan-derivative compounds and structures, methods of making chitosan-derivative compounds and methods for controlling, inhibiting and enhancing microbial populations in a variety of environments. The present invention is also directed to the control, inhibition and enhancement of microbial populations in animals, particularly humans. The microbial populations include bacteria, viruses and other pathogens where control of microbial populations are a necessity. The chitosan-derivative compounds of the present invention include chitosan-arginine compounds, related chitosan-L/D unnatural amino acid compounds, chitosan-acid amine compounds, chitosan-L/D natural amino acid derivative compounds, co-derivatives of the chitosan-derivative compounds, salts of the chitosan derivative compounds, and chitosan-guanidine compounds.

This disclosure provides generally for antimicrobial compositions and methods of use comprising an anthocyanin, an anthocyanidin or metabolites thereof. Methods for promoting healing of a wound using these compositions are also disclosed. These compositions have broad spectrum antimicrobial activity and are safe for human and animal uses. Further, these compositions are safe for medical uses and industrial uses as antiseptic preparations to reduce or prevent microbial growth, including killing bacterial biofilms.

It is an object to provide a novel wet wiper in which a sterilization effect and a wiping/cleaning effect are maintained even when the wet wiper is stored for a long period of time. A wet wiper is provided which includes: a fabric; and a chlorine-based treatment agent included in the fabric, wherein the chlorine-based treatment agent includes at least one of chlorous acid (HClO.sub.2), chlorite ion (ClO.sub.2.sup.), and chlorine dioxide (ClO.sub.2) as an effective chlorine component.

A device for cleaning a handle, includes a handle including a gripping surface to be disinfected, an application member for applying a cleaning liquid to the gripping surface, and cleaning liquid supply including at least one reservoir for receiving cleaning liquid and distributing it to the application member. The application member includes at least one buffer reserve arranged in contact with the gripping surface. The device includes a unit for actuating the application member, including a driver configured to move the buffer reserve and/or the gripping surface relatively with respect to one another so as to apply cleaning liquid to substantially the entire gripping surface during this movement.
