The goal of this research effort is to combine a number of high quality detection techniques together in order to identify hazardous materials. These techniques include (1) elemental analysis for hazardous materials using neutron interrogation and gamma ray spectrum analysis techniques as well as associated α-particle imaging techniques, (2) ion mobility using new miniaturized instrumentation in simple ion trap instruments, (3) point-of-need chemical analysis systems for analyses in aqueous systems using antibody arrays on micro-chips, (4) micro-sensors using advanced scanning probe microscope (SPM) technique on gold and silicon surfaces coated with antibodies and antigen in both dry and aqueous environments. The combination of several of these techniques into a single decision process gives broad response capability with a reduction in false signals.
