Diagnosis of dengue infection using a modified gold electrode with hybrid organic-inorganic nanocomposite and Bauhinia monandra lectin

► A sensitive and selective biosensor for dengue serotype was successfully developed. ► BmoLL recognition may be attributed to different patterns of glycoproteins in the sera. ► AuNpPANI-BmoLL was used to fabricate a dengue nanobiosensor with low detection limit.
