The present disclosure relates to multi-functional anti-microbial polymers comprising a first monomer having a polymerizable cyclic aromatic moiety which forms part of the backbone of the polymer and a second monomer having an ethylenically unsaturated monomer having a double or triple bond and a quaternary ammonium or quaternary phosphonium moiety.

A sterilizing mouthpiece assembly for reducing the airborne transmission of infectious diseases includes a mouthpiece for positioning in a user's mouth. A shelf is integrated into the mouthpiece and a wedge extends upwardly from the shelf. A plurality of first light emitters is each of the first light emitters is integrated into the mouthpiece and each of the first light emitters emitting light in the ultraviolet spectrum to sterilize the inside of the user's mouth. A plurality of second light emitters is each positioned on the wedge and each of the second light emitters emits light in the ultraviolet spectrum to sterilize the inside of the user's mouth.

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.

Methods and compositions for the prevention or reduction of platelet transfusion associated complications are provided. The subject methods include modifying donor whole blood or platelets prior to transfusion to prevent or reduce alloimmune platelet refractoriness.

The mitigation of indoor pathogens comprises quantifying, using a bio-aerosol monitoring system, the amount of total pathogens in the air and on surfaces within an indoor environment. Moreover, the process comprises sanitizing the indoor environment with portable equipment to stabilize the indoor environment when it is determined that the indoor environment is contaminated. Also, the process comprises installing a purification device within a contaminated area of the indoor environment, and monitoring continuously, the indoor environment after sanitizing, for pathogens. Still further, the process comprises releasing a purifying agent upon detecting pathogens in the indoor environment, and providing periodic maintenance to the purification device.

The current pandemic due to Covid-19 stresses the importance of effectively treating highly contagious and deadly infections. The described medical device is meant to help the medical community by enabling them to treat patients more effectively. The delivery mechanism focuses on the mucous membrane. It is noninvasive and easy to use by patients directly. The device is hand-held, with incorporated germicidal UVC lights. It has two chambers connected by an internal application tip. The tip connects to a removable container which can be used with the prescribed treatment/therapy, vaccine, or viral testing fluid/reagent, as needed. Due to its versatility, non-invasive nature and germicidal properties, this device supports rapid response to infectious diseases, such as COVID-19. It may also further promote the development and use of different inoculation and drug techniques and delivery systems by enabling easy administration, via the mucous membrane.

A method for sterilizing biological materials is disclosed. A dehydrated biological material is put into a closed container. The closed container is then decompressed under a vacuum. Subsequently, 0.01 g/m.sup.3 to 1000 g/m.sup.3 of a sterilizing gas, i.e., pure ozone, is introduced into the container for a period of time until the biological material is sterilized.
