Developing electrochemical sensors to detect dopamine and paracetamol in the body is an active field of research. A team from the Jawaharlal Nehru Centre of advanced scientific Research, Bengaluru, has come up with materials which will help in detecting the levels, in combination, in spiked urine and serum samples. Neurotransmitters transmit signals from one neuron to another and dopamine is one such which is responsible for reward-motivational behavior, among other things. The incorrect amount may lead to disease s like Parkinson’s disease. Paracetamol is a drug commonly used to treat pain and fevers; however, if the concentration of the same goes above then it can lead to the sympathetic nervous system. Due to the high surface area, non-toxicity, chemical inertness, reverse redox reaction and high surface oxygen mobility of the electrode which is chemically modified they are highly preferred. There has been changed in the chemicals used for doping to meet the requisite criteria. “The peak position of dopamine and paracetamol is fixed at 160mV and 360mV, respectively. Peak current increases linearly with the concentration of dopamine and paracetamol”. The researchers found that the performance of an electrode using platinum doped cerium oxide and cuprous oxide is better than the cerium oxide-graphene materials.
