Abstract
Biological cells or spores are analyzed by using enhanced THz coupling to molecules by depositing a test material in a channel of a microfluidic chip using near field sensing of sub-THz radiation from the molecules. The THz radiation is enhanced by transmitting THz radiation through slots in the chip, illuminating molecules of the test material with the enhanced THz radiation transmitted through the slots. A spectroscopic signature of the test material is generated, and a database of signatures of materials is generated. The test material is identified by comparing the signature of the test material with signatures of materials in the database.
