The present disclosure provides methods, devices, systems and compositions for detecting and/or modifying chemical agents. In some embodiments, a biosensor may be configured to detect a chemical agent, modify that agent to a form with reduced toxicity, and/or detect the modified form of the chemical agent. The present disclosure also relates, in some embodiments, to variant organophosphorus hydrolase having one or more desirable amino acid substitutions. |
