Methods and related devices for impinging light on tissue, for example within a body of a patient, to induce various biological effects are disclosed. Biological effects may include at least one of inactivating and/or inhibiting growth of one or more pathogens, upregulating a local immune response, stimulating enzymatic generation of nitric oxide to increase endogenous stores of nitric oxide, releasing nitric oxide from endogenous stores of nitric oxide, and inducing an anti-inflammatory effect. Wavelengths of light are selected based on intended biological effects for one or more of targeted tissue types and targeted pathogens. Light treatments may provide multiple pathogenic biological effects, either with light of a single wavelength or with light having multiple wavelengths. Devices and methods for light treatments are disclosed that provide light doses for inducing biological effects on various targeted pathogens and targeted tissues with increased efficacy and reduced cytotoxicity.

Phototherapeutic light for treatment of pathogens

Systems and methods for phototherapeutic modulation of nitric oxide in mammalian tissue include use of a first wavelength and first radiant flux of light to stimulate enzymatic generation of nitric oxide, and use of a second wavelength and second radiant flux of light to stimulate release of nitric oxide from endogenous stores of nitric oxide. Pulsed light and/or partially non-overlapping light impingement windows may be used. Non-coherent light impinged on tissue may include a peak wavelength in a range of from 410 nm to 440 nm in the absence of light emissions having a peak wavelength of from 600 nm to 900 nm.

Systems and methods for phototherapeutic modulation of nitric oxide

Provided herein are compounds, compositions, and methods for modifying mucus, including modifying mucus using nitric oxide-releasing biopolymers (e.g., NO-releasing chitosan oligosaccharides). In some embodiments, a compound, composition, and/or method of the present invention modifies one or more properties of mucus to increase mucus clearance in a subject and/or prevents the growth or kills one or more pathogens present in mucus of a subject.
