Method for concentration and separation of biological organisms by ultrafiltration and dielectrophoresis

Patent Simmons, Blake A.; Hill, Vincent R.; Fintschenko, Yolanda; ...

Disclosed is a method for monitoring sources of public water supply for a variety of pathogens by using a combination of ultrafiltration techniques together dielectrophoretic separation techniques. Because water-borne pathogens, whether present due to "natural" contamination or intentional introduction, would likely be present in drinking water at low concentrations when samples are collected for monitoring or outbreak investigations, an approach is needed to quickly and efficiently concentrate and separate particles such as viruses, bacteria, and parasites in large volumes of water (e.g., 100 L or more) while simultaneously reducing the sample volume to levels sufficient for detecting low concentrations ofmore » « less

Apparatus and method to control atmospheric water vapor composition and concentration during dynamic cooling of biological tissues in conjunction with laser irradiations

Patent Nelson, J Stuart [Laguna Niguel, CA]; Anvari, Bahman [Houston, TX]; Tanenbaum, B Samuel [Irvine, CA]; ...

Cryogen spray cooling of skin surface with millisecond cryogen spurts is an effective method for establishing a controlled temperature distribution in tissue and protecting the epidermis from nonspecific thermal injury during laser mediated dermatological procedures. Control of humidity level, spraying distance and cryogen boiling point is material to the resulting surface temperature. Decreasing the ambient humidity level results in less ice formation on the skin surface without altering the surface temperature during the cryogen spurt. For a particular delivery nozzle, increasing the spraying distance to 85 millimeters lowers the surface temperature. The methodology comprises establishing a controlled humidity level inmore » « less

Concentrated formulations and methods for neutralizing chemical and biological toxants

Patent Tucker, Mark D.; Betty, Rita G.; Tadros, Maher E.

A formulation and method of making and using that neutralizes the adverse health effects of both chemical and biological toxants, especially chemical warfare (CW) and biological warfare (BW) agents. The aqueous formulation is non-toxic and non-corrosive and can be delivered as a long-lasting foam, spray, or fog. The formulation includes solubilizing compounds that serve to effectively render the CW or BW toxant susceptible to attack, so that a nucleophillic agent can attack the compound via a hydrolysis or oxidation reaction. The formulation can kill up to 99.99999% of bacterial spores within one hour of exposure.

Method for the concentration and separation of actinides from biological and environmental samples

Patent Horwitz, E Philip [Naperville, IL]; Dietz, Mark L [Tucson, AZ]

A method and apparatus for the quantitative recover of actinide values from biological and environmental sample by passing appropriately prepared samples in a mineral acid solution through a separation column of a dialkyl(phenyl)-N,N-dialylcarbamoylmethylphosphine oxide dissolved in tri-n-butyl phosphate on an inert substrate which selectively extracts the actinide values. The actinide values can be eluted either as a group or individually and their presence quantitatively detected by alpha counting.
