The conventional real-time polymerase chain reaction (PCR) used in clinical settings is slow (>1 h). We describe the development of a real-time PCR system for the rapid, high sensitivity detection of infectious diseases. We have improved the polymer-based PCR chip and thermal control unit. A polymer with high thermal diffusivity, thermal conductivity, and glass transition temperature was used for the PCR chip. The thermal control unit consisted of a denaturing block, an annealing/extension block, and a cooling block set at 20 ℃. The heating and cooling rates were 7.2 and −14.2 ℃/s, respectively. The cooling rate was 10 times higher with the cooling block than without the cooling block. Using this rapid real-time PCR system, we sucessfully detected mycoplasma genomic deoxyribonucleic acid with a detection limit of 6.0 × 10−5 ng/µL in 8.5 min.
