To establish a detection platform for measuring the biological effects of FIR, we measured the migration of rat renal tubular epithelial cells (NRK-52E) using a ceramic full-wavelength FIR generator (1–25 μm). We found that FIR significantly promoted cell migration using our standardized method (Fig. 1a). We defined the ratio of the FIR-promoted migration area to the migration area of the control group as the FIR biological index (FBI). A higher FBI indicates a greater biological effect of FIR. Increasing the distance between the FIR irradiation source and cells is expected to reduce the intensity of FIR. After measurement and calculation, the intensity of the FIR emitter was 0.13, 0.07, 0.05, and 0.03 mW/cm2 at an irradiation distance of 3, 4, 5, and 6 cm, respectively. The FBI peaked at an irradiation distance of 3–4 cm and decreased at longer distances (Fig. 1b), which suggested that the most effective intensity of FIR for cell...
