Do you know the reason behind farmers putting on protective stuff while applying the organophosphate pesticides? The reason is that organophosphate is a toxic chemical utilized as pesticides in agricultural as well as a nerve agent in biological warfare. If anyone is exposed to organophosphates, it can result in severe illness or even death if they fail to take suitable safety measures. Quick and precise point-of-use recognition of organophosphate nerve agents or pesticides would enhance security in defense as well as food safety scenarios.
At present, a research team has designed a rapid approach to identify the existence of these compounds with the use of a non-refundable “lab-on-a-glove.” The organophosphate nerve agents such as VX and sarin are extremely lethal and can stop the nervous system from functioning appropriately. The organophosphate pesticides are no that effective but function in the same manner and can result in illness in individuals who are exposed to them. With this intention, Joseph Wang and team has designed a wearable sensor that can meet the needs of field detection.
The new wearable, supple glove biosensor performs the electrochemical biosensing and sampling steps on unlike fingers. The thumb finger is utilized for gathering the nerve-agent residues, whereas an enzyme is halted on the index finger. A stretchable ink was produced by the team for detecting compounds on these fingers and to print the collection. The identification of the collected remains is carried out when the thumb comes in contact with the printed enzyme-based organophosphate biosensor on the index finger of the glove. Thus, a user will need to swipe the glove’s thumb on a surface for detection, and then let the index finger and thumb come in contact with each other for the electrochemical analysis. For instantaneous outcomes, the voltammetric information is sent through a reusable Bluetooth device located on the rear of the glove to the mobile device of the user. The glove can sense organophosphate pesticides methyl paraoxon and methyl parathion on several surfaces, such as wood, plastic, & glass, and on produce.
Thus, these results bring up new avenues for various defense and food applications, isn’t it?
