To assist in airport surveillance efforts, a biosensor based on antibody recognition of individual explosives and drugs has been developed at the Naval Research Laboratory. Analysis of samples containing ng/mL levels of the material are completed in under one minute. Immunoassays for the explosives and the five major drugs of abuse are currently available. The intrinsic nature of antigen-antibody binding also provides the unit with an inherently high degree of selectivity. A portable version of the biosensor that can be run by non-technical personnel is also being engineered. The device, including pumps and fluorometer, will be housed on a modified PCMCIA cartridge fitted into a laptop computer. To run assays, a disposable coupon containing the antibody/fluorescent-antigen complex is inserted into the unit and samples are introduced via a sampling port. Results can be viewed in real time or stored on the computer for later data retrieval and analysis.
