A review on advances in the development of electrochemical sensors for the detection of anesthetic drugs

“…The sensor was able to produce linear detection in the range 0.01-45 mM L −1 with an LOD of 2 nM L −1 . 42 Codeine is an opioid, which has been found to provide analgesia in few individuals suffering from acute postoperative dental pain. 43 Electrochemical sensors can also be used for the detection of codeine due to this important role.…”

Controllable synthesis of Pt nanoparticles on graphene oxide nanosheets and its application for electrochemical determination of dopamine

“…In addition, GO as a promising supporting material has been popularly used in electrochemical sensor field due to its large specific surface area, unique electronic properties and conductivity. [16][17][18][19] GO not only disperses and stabilizes inorganic nanoparticles but also provides fertile opportunities for the adsorption of molecules, which facilitates the construction of efficient sensors. Dopamine (DA) [20][21] is one of the familiar neurotransmitter that is used to transfer information in the central nervous system.…”

“…Diverse oxygen‐containing functional groups were linked to the carbon atoms, including carboxylic, hydroxyl and epoxide, which enhanced its solubility and stability. In addition, GO as a promising supporting material has been popularly used in electrochemical sensor field due to its large specific surface area, unique electronic properties and conductivity [16–19] . GO not only disperses and stabilizes inorganic nanoparticles but also provides fertile opportunities for the adsorption of molecules, which facilitates the construction of efficient sensors.…”
