Abstract

square wave voltammetry (SWV). An S-shaped calibration curve was obtained, with a linear response in the 5 pM-100 nM range and a limit of detection of 10 pM. Specificity and real-sample analysis using human blood serum revealed high selectivity toward CHIKV E1, with a signal recovery rate of 93-102%. Overall, our findings indicate that the developed electrochemical sensor platform is a promising tool for the sensitive and specific detection of the Chikungunya virus protein.
