A method for preparing a biological composition for degrading plant pesticide residues includes: (1) preparing a mixture of a dried coconut shell powder having a water content of less than 3 wt % and a particle diameter of not more than 2 mm and a dried licorice powder having a water content of less than 1 wt % and a particle diameter of not more than 2 mm; (2) hydrolyzing the mixture in a cellulase buffer at pH 4.5 to 5.5 for at least 36 hours, and filtering the mixture to obtain an enzymatic hydrolysate; and (3) adding the enzymatic hydrolysate to a bacteria mixture of yeast and lactic acid bacteria and fermenting at 30 C. to 35 C. for 7-10 days, and centrifuging and lyophilizing to obtain the biological composition.

A genetically modified polypeptide is disclosed which comprises an amino acid sequence of phosphotriesterase (PTE) having at least twice the catalytic efficiency for a V-type nerve agent as a polypeptide which consists of the sequence as set forth in SEQ ID NO: 1, when assayed under identical conditions.

A CT value controller includes a storage means, an input means, and a computing means. The storage means stores a function expressing a relative humidity and a CT value regarding a degradation degree of an anticancer agent, an assumed relative humidity, and a CT setting. The input means inputs a measured relative humidity and a measured ozone concentration at a time of degradation treatment of the anticancer agent. The computing means calculates a corrected CT value increment based on a difference between the measured relative humidity and the assumed relative humidity at every input of the relative humidity and the ozone concentration by using the function. The computing means determines a termination of the degradation treatment of the anticancer agent when an integrated CT value of the corrected CT value increments reaches the CT setting.

A composition for decomposing pharmaceutically active agents, comprises up to 30 wt. % oxidizer; and up to 30 wt. % immobilizer; wherein the wt. % is based on a total weight of the composition.

The present invention relates to a method of detoxifying a liquid chemical agent using a metal organic framework having a surface modified with a basic amine-based compound. More particularly, a surface-modified metal organic framework having the amine-based compound deposited on a surface thereof and in pores thereof or bonded to the inside of a frame is prepared, and when the surface-modified metal organic framework comes into contact with the liquid chemical agent, a reaction with moisture in the atmosphere occurs, thus removing the liquid chemical agent through a hydrolysis reaction. It is possible to simultaneously detoxify various chemical agents such as a nerve agent and a vesicant, thus assuring a high detoxification effect on liquid chemical agents at room temperature even when using a small amount thereof.

A composition for decomposing pharmaceutically active agents, comprises up to 30 wt. % oxidizer; and up to 30 wt. % immobilizer; wherein the wt. % is based on a total weight of the composition.

A method for decontamination of a toxic substance is disclosed. The method includes fabricating a plurality of nanomotors, and putting the plurality of nanomotors in contact with a contaminant solution comprising the toxic substance. Fabricating the plurality of nanomotors includes preparing a mesoporous silica template, forming the plurality of nanomotors within the mesoporous silica template, and separating the plurality of nanomotors from the mesoporous silica template. The mesoporous silica template includes a plurality of channels, where each channel of the plurality of channels have a diameter less than about 50 nm and a length of less than about 100 nm, and each nanomotor of the plurality of nanomotors is formed within a channel of the plurality of channels. Putting the plurality of nanomotors in contact with the contaminant solution includes adding hydrogen peroxide (H.sub.2O.sub.2) and the plurality of nanomotors to the contaminant solution.

A method of employing an assembly containing a shelf-stable formulation for decontaminating skin exposed to nerve agents in a package forming a first chamber and a second chamber separated by a barrier with water located in the first chamber and a dry sponge and diacetylmonoxime or derivatives thereof, located in the second chamber, wherein the diacetylmonoxime is distributed within the sponge, the method comprising opening the barrier between the first and second chambers, shaking the package to move the water into sponge until the sponge is wet, tearing open the package, removing the sponge and wiping the sponge on skin. Preferably polyethylene glycol is distributed in the sponge and wiping the sponge on the skin leaves a mixture of diacetylmonoxime and polyethylene glycol on the skin.

Agents for decontaminating and/or neutralizing organophosphorus compounds (e.g., nerve agents, pesticides) and methods of using those agents are disclosed. Preferred agents comprise aminoguanidine imines, and these agents do not require a strongly alkaline environment to be effective. The aminoguanidine imines can hydrolytically decontaminate substantially all of the target organophosphorus compound(s) in a matter of minutes.

An immobilized enzyme electrode includes: an electrode; a redox enzyme that oxidizes or reduces a target molecule; and an electron carrier that performs electron transport between the electrode and the redox enzyme. The electron carrier is immobilized on the electrode via a first linker that is in a form of a chain, and the redox enzyme is immobilized on the electrode via a second linker that is longer than the first linker, the second linker being in a form of a chain.
