Abstract
Improved surface-enhanced Raman scattering (SERS) substrates comprising chemically-derivatized magnetic microparticles complexed with metal colloidal particles or substrates. The SERS substrates permit collection, detection, measurement, and/or analysis of analytes present at concentrations ranging parts per trillion to parts per billion. Further, compositions, methods, and devices that provide for rapid and/or sensitive detection of chemical compounds of interest present in small concentrations. The subject matter has use in the areas of homeland security and force protection, for example, in the detection of trace samples including, for example, BTEX (benzene, toluene, ethylbenzene, and xylenes), chlorinated solvents, TNT, nerve agents, blister agents, metal ions, anions, antigens, peptides, nucleic acids, spores, fungi, viruses, and bacteria.
