Abstract
Polymerase chain reaction (PCR) amplification of short tandem repeats (STR) present in the human genome is critical for forensic human identification. Presented here is the first report of non-contact temperature control for human genetic profiling. The non-contact temperature control consists of IR-mediated heating, convective cooling, and interferometic temperature sensing. The interferometer is originally calibrated with a miniature thermocouple in the PCR chamber resulting in a temperature sensitivity of 24.1 nm/°C. The calibration is successfully used to amplify a region of λ-phage DNA. Ultimately, 9 STR loci are successfully amplified for human identification.
