2021-08-09· The effect of the scan rate on the electrochemical response of the developed sensor was studied in Fig. 4c, which shows the SWV voltammograms of 50 nmol L −1 of the COVID-19 protein under different scan rates (from 10 to 100 mV/s). The results demonstrated that the redox current peaks were increased with increasing the potential scan rate; besides, the potential oxidation peak was shifted to ...
Any of the common symptoms like vomiting, headache, weakness and unconsciousness is only an indication and a starter for eventual deaths. So, Carbon monoxide should be detected on time so that you do not run the risk of losing your life. The presence of the carbon monoxide is measured in parts per million or the ppm, which should be around 50 ppm.

How electrochemical CO sensors detect gas. Gas that enters the sensor undergoes an electrochemical reaction that causes a change in the electrical output of the sensor. The difference in the electrical output is proportional to the amount of gas present. Gas enters the sensor through an external diffusion barrier that is porous to gas but nonporous to liquid. An internal organic vapor filter ...
