Electrochemical Determination of Japanese Encephalitis Virus Antigen Using Silver Nanoparticles Modified Screen-Printed Carbon Electrode

In this study, we aim to fabricate a silver nanoparticles (Ag NPs) based electrochemical biosensor for Japanese Encephalitis virus antigen detection. Ag NPs were deposited onto screen-printed carbon electrode (SPCE) and the electrochemical properties of the Ag NPs modified SPCE were investigated via...
