摘要：

A continuous-flow polymerase chain reaction (PCR) device with integrated heaters for DNA amplification was studied. We developed a numerical model to predict the temperature variations of a 3D-printed PCR device for different heater temperatures. The target temperatures at thermal zones for a successful PCR are 95 degrees C, 55 degrees C, and 72 degrees C for denaturation, annealing and extension, respectively. A numerical simulation was conducted to determine the heater temperatures required to compensate for heat loss. Our numerical model and optimization method were confirmed by comparison with the experimental results. Consequently, the compensated heater temperatures required to achieve the target temperatures are 97.9 degrees C, 56.6 degrees C and 74.1 degrees C. The proposed optimization method and numerical simulations will be useful in achieving highly effective thermal cycling in the 3D-printed PCR device.
