Simple CBD Method to Fabricate Pencil Graphite Electrodes ACS_AMI
By Shaheer RehanSep 22 2022Reviewed by Megan Craig, M.Sc. Selenium nanoparticles are a good choice for biological and electrochemical sensing applications due to their low toxicity.
Irrespective of its commercial importance, even in tiny doses, it is a hazardous chemical that poses a major concern due to its cancerous and mutagenic properties. Hydrazine has been classified as a carcinogen and neurotoxin in humans. Amperometry has the highest sensitivity and selectivity towards electroactive substances of all electrochemical sensing methods. A notable field of study in recent times has been the fabrication of nanoparticle electrodes for the electrochemical sensing of hydrazine.
Advantages of the Chemical Bath Deposition Method The chemical bath deposition approach is quite attractive among the several ways to produce nanoparticles because it has some intrinsic benefits over traditional approaches. What Did the Researchers Do? In this study, the team proposed the production of a pencil graphite electrode coated with selenium nanoneedles for the electrochemical sensing of hydrazine using a simple chemical bath deposition approach.
