Plasma activation of gold electrodes for the preparation of electrochemical aptamer-based biosensors

Electrochemical aptamer-based sensors (aptasensors) are a promising type of biosensor that can be potentially used as a
biomedical diagnostic tool to detect a wide range of biochemicals with remarkable sensitivity and selectivity. However, the surface
of electrochemical aptasensors is susceptible to degradation and etching, which can compromise their reliability and stability. To
address this issue, we propose investigating the use of a novel plasma surface treatment methods to modify the sensors’ surfaces
and optimize their stability and robustness. Furthermore, the study will provide insights into the immobilization efficiency of
aptamers and bio-sensing performance of electrochemical aptasensors. The outcomes of this research will have a significant
impact on the development of more sensitive, reliable, and selective electrochemical aptasensors for applications in point-of-care
(PoC) biomedical diagnostics.
