Abstract: Present invention discloses methods and devices for treating skin and nail infections such as onychomycosis and dermatophytosis, caused by pathogenic microbes such as fungi. in a preferred embodiment, a method for treating skin and nail infections comprises irradiating the treatment site with a light radiation source operating at one or more near infrared wavelengths which are absorbed by the pathogenic microbes, specifically operating at 980±30 nm, 1470±40 nm and/or 1900±60 nm. In another preferred embodiment, a method for treating skin and nail fungus comprises irradiating the treatment site with a device emitting laser radiation of 980±30 nm wavelength. In another embodiment, a device for treating toenail fungus comprises a laser radiation source which emits a combination of radiation wavelengths at about 980±30 nm and 1470±40 nm; or 980±30 nm and 1900±60 nm; or 1470±40 nm and 1900±60 nm; or 980±30 nm, 1470±40 nm and 1900±60 nm.

Abstract: Systems and methods of providing a covert security marking for items such as documents, packaging, credit cards, and other valuable goods to combat the steady increase in forgery, counterfeiting, and other fraudulent activities is presented. A spectrally narrow, near infrared ink system serves as the basis of a covert security feature for items of value. Alternatively, or in combination, metal oxides having a substantially narrow absorption band and a maximum absorption wavelength of electromagnetic radiation in the near infrared range are also utilized.

Abstract: Methods, devices and composition are disclosed for treating oral, skin and nail diseases, including inflammatory periodontal disease, onychomycosis and dermatophytosis. In a preferred embodiment a method for treating oral, skin and nail infections comprises administering a photosensitizing compound in long term effect or timed release formulations, including local highly concentrated formulations, and activating the photosensitizer with radiation to selectively destroy bacteria, fungi and other microbial bodies. In another preferred embodiment, photosensitizers are housed within nanoparticles, and can be gradually released through biodegradation or periodically released by such processes as brushing, irradiation and chemically induced release. The diffusion speed of the photosensitizers can be accelerated by brushing. In another embodiment, the photosensitizer molecule is also modified to more effectively target the molecule to the unwanted oral bacterial and fungal species.
