The smoke removal device with smart detection has the capability of gas detectionindoor air circulation. The system is internally equipped with a sensing device. If an abnormal PM2.5 valuea high concentration of dangerous gas is detected, the fan can be automatically activated immediately to quickly filter the air,both preventivemonitoring functions can be achieved.

Our PEDD has been used to detect the HNE level in both tearwound fluids of 9 patients,the limitations of detection were about 0.76 μg/mL0.63 μg/mL respectively. Our device requires only 15 minutes, 3 μL of clinical sample for each test,offers superior sensitivity compared to other current HNE detection methods. The HNE concentrations in the patient samples have shown that the elevated HNE levels might suggest an abnormal healing of either acutechronic wounds, consistent with previous studies that showed excess protease levels in all non-healing wounds.
