Bhavna S. Hedau (Doctoral student) from the research team of Professor Tae-Jun Ha (Department of Electronic Material Engineering) received the Best Paper Award at 2023 Fall Conference of the Korean Sensors Society for her research on ‘Highly sensitive and selective enzyme-free electrochemical biosensors for the detection of bioactive molecules’.

The synthesis of a cobalt-carbon matrix with strong negative electrical properties through π-π bonding was conducted for a highly sensitive enzyme-free biosensor aimed at detecting dopamine and glucose using electrochemical methods. This allowed the detection of dopamine down to concentrations as low as 10 nM. Additionally, synthesizing nanocomposites based on polyaniline and reduced graphene oxide, functionalizing silver nanoparticles as catalysts, enabled the sensitive detection of glucose down to concentrations as low as 0.79 μM. Particularly, this research was recognized for its excellent potential applications in the field of biosensors for the diagnosis of neurological disorders and metabolic disorders.
