1 In the process proposed here, 20 nm Au nanoparticles (AuNPs) are deterministically arranged in precise placement by manipulating a topographically patterned poly(dimethylsiloxane) (PDMS) stamp, and Ag nanoparticles are conjugated with AuNP patterns to construct surface-enhanced Raman scattering (SERS)-active substrate to detect trace amounts (10(-13) mol/L) of biological molecules such as thrombin with enhancement up to 10(10).
