The present invention is directed to a system and method for photoeradication of microorganisms from a target. The method includes the step of obtaining test data for a plurality of experiments each of which comprises irradiating test microorganisms with a plurality of light pulses having a wavelength that ranges from 380 nm to 500 nm. The light pulses have a plurality of pulse parameters (peak irradiance, pulse duration, and off time between adjacent light pulses) and are provided at a radiant exposure that ranges from 0.5 J/cm.sup.2 to 60 J/cm.sup.2 during each of a plurality of irradiation sessions. The test data comprises a survival rate for the test microorganisms after irradiation with the light pulses. The method also includes the step of analyzing the test data to identify the pulse parameters for the light pulses and the radiant exposure for each of the irradiation sessions that result in a desired survival rate for the test microorganisms. The method further includes the step of irradiating the microorganisms of the target with light pulses having the identified pulse parameters at the identified radiant exposure for each of the irradiation sessions so as to photoeradicate all or a portion of the microorganisms.

A therapeutic endotracheal tube assembly is provided for insertion into a patient's trachea to ventilate, to maintain patency of the patient's airway, and to deliver therapeutic electromagnetic radiation (EMR) to the patient. The therapeutic endotracheal tube assembly has an endotracheal tube and an EMR delivery system. The EMR delivery system has an EMR source for emitting non-ultraviolet, therapeutic EMR having intensity sufficient to activate desired therapeutic properties within the patient and an EMR conduction line conducive to the propagation of EMR from the EMR source along the endotracheal tube. The EMR conduction line is removably insertable into the endotracheal tube. The therapeutic endotracheal tube assembly may be custom made or may be constructed by retrofitting a removably insertable EMR delivery system to an existing endotracheal tube.

This invention provides a method and device for disinfecting any products, materials or environment as any complex of physical, chemical, and biotic factors that can include gases, liquids and solids like soil or artificial plant growing media or animals and plants comprising the step of treating them with one or more infrared lights of LED emitters.

A sterilization apparatus includes a light source unit for emitting light to a sterilization region for sterilizing a target particle, a power supply unit for supplying power to the light source unit, and a photodiode unit for sensing the light from the light source unit. The photodiode unit is driven by the light from the light source unit.

Portable multifunctional device designed for sanitizing of inner and outer surfaces of shoes, sanitizing of air, water, household items and surfaces, treatment of skin and wound infection, nails fungus, cosmetic use, and detection of counterfeit currency. The device is able to perform all the above sanitizing, therapeutic and cosmetic functions that would otherwise be carried out by various different devices. The enhance functionality has been accomplished without alteration of any parts of the device. Apparatus utilizes light radiation in three diapasons: 100-280, 405-495, and 700-1064 nm and provides distant sanitizing. Apparatus comprises at least one module with a dual DC-AC power supply. Each module has a germicidal unit, retractable flexible shaft, shade, and housing. The flexible shaft allows positioning the germicidal units under different angle for uniform distant illumination. The device is suitable for household, traveling, and military use.

Methods and apparatus provide therapeutic electromagnetic radiation (EMR) for inactivating infectious agents in, on or around a catheter residing in a patient's body cavity and/or for enhancing healthy cell growth. The method comprises transmitting non-ultraviolet therapeutic EMR substantially axially along an optical element in a lumen of the catheter body and/or the catheter body. Through delivery of the therapeutic EMR to particular infected areas and/or areas requiring tissue healing. The methods and apparatus of the present disclosure inactivate the major sources of infection in, on, and around catheters and/or enhance healthy cell growth around catheters.

Dehydration and drying are some of the oldest methods of preserving food and other biological materials such as proteins and both live and dead live microorganisms or their metabolites. The invention disclosed herein seeks a method of further improving the process of preserving biological material by combining the freezing or freeze-drying process with a partial infrared dehydration step. By using infrared radiation energy to perform simultaneous blanching and dehydration, the drying speed is greatly increased and better cellular and molecular integrity is maintained. The invention herein is also particularly useful in connection with cannabis and hemp.
