Novel GO-ssDNA based biosensor incorporated with dual-antibody modified PLLA NPs.
Simultaneous detection of VEGF and PSA in same one electrochemical biosensor.
Achieving wide linear range of detection of 0.05–100 (VEGF) and 1–100 ng/mL (PSA).
Highly sensitive and selective detection of VEGF and PSA was achieved in human serum.
