  • Patent number: 12232492
    Abstract: There is proposed a method for the sterilization of products containing bacteriophages in a manner that will allow the bacteriophages to retain their activity and infectivity. Products containing bacteriophages are exposed to supercritical CO2 under conditions causing little or no damage to structural integrity of the bacteriophages or to the structural properties of biodegradable scaffolds containing the bacteriophages.
    Type: Grant

  • Publication number: 20230363396
    Abstract: A method of eliminating, reducing or preventing bacterial contamination of a surface, the method comprising dispersing a bacteriophage containing composition in air in proximity to the surface. In some embodiments, the bacteriophage containing composition is a powder dispersed by pressurizing a load chamber containing the powder so that the powder is expelled through an outlet. Also, devices for performing the method and a powder used in the method.

  • Publication number: 20230241005
    Abstract: Cannabidiol (CBD) is the major nonpsychotropic constituent of cannabis, having numerous applications in the management of clinical conditions, including the treatment of chronic pain. The delivery of CBD and other cannabinoids is hindered by poor bioavailability, low aqueous solubility, and instability in the solution form, hepatic first pass effect, enzymatic degradation in the gut, and mucociliary clearance. We propose the encapsulation of cananbinoids in biodegradable polyester amide urea polymer, and in similar polymers, for the optimized prolonged topical delivery and permeability of CBD for pain, inflammation and other conditions.
