Biosensing made easy with PEG-targeted bi-specific antibodies. | LitMetric
Whilst recent advances in nanotechnology have yielded many new biosensing capabilities, innovative biological attachment and detection modalities remain relatively underdeveloped. Bi-specific antibodies (bsAbs)--which exhibit binding capability for two separate targets--offer an inherent advantage over conventional antibody reagents by significantly simplifying sensor surface preparation. Herein, we report the deployment of bsAbs for simultaneous attachment to a polymer-coated transducer and label-free, electrochemical (EC) detection of target antigens.
