Abstract: Provided are foams and foamable formulations for the decontamination of surfaces, such as disinfection from COVID-19. The formulations can allow deposition of a uniform layer of foam on a given surface without spontaneous drainage of water and with near zero flowability. The foam can adhere to slanted surfaces and surfaces comprised of a variety of materials, including wood, glass, and stone, enabling safe and effective viral decontamination in a number of settings.

Abstract: The disclosed subject matter relates to a bleach foam formulation, and to methods of use of the bleach foam formulation for the decontamination of surfaces exposed to infectious agents. disclosed subject matter provides a method for the delivery of the bleach foam formulation for the decontamination of surfaces, and specifically for the decontamination of health workers' personal protection suits, exposed to Ebola, SARS or other infectious agents. In certain embodiments, the use of the bleach foam formulation involves the delivery of the bleach foam from distances for the safe disinfection of contaminated surfaces.

Abstract: Fibrillar bacterial proteins can be mixed with oil in or on water. The interaction of the proteins at the oil-water interface can result in oil dispersion in water in the form of droplets surrounded by an aggregated protein film. The film may be formed by multiple layers of the fibrillar proteins with water between adjacent protein layers. The proteins may be derived from bacterial cells, such as Bacillus subtilis. The encapsulated oil droplets can be collected from the water, for example, as part of an oil spill clean-up or oil storage. The oil may be removed from the collected droplets, for example, by evaporation to produce a three-dimensional network composed of the aggregated films. The three-dimensional network material can be used as a coating for transplant material, grafted onto implant material to improve biocompatibility, as a precursor for tissue growth or engineering, or provided into a human or animal body.
