Biosensing materials for monoclonal antibody detection: An overview

Considering the continuous advances in the synthesis and clinical applications of monoclonal antibodies (mAbs), precision therapies that employ mAbs are essential. In recent years, extensive efforts have been invested in developing novel strategies or technologies for detection of mAbs. Given the availability of advanced biosensing materials, various assemblies of multifunctional materials can be prepared by intelligent design when evaluating targets for mAbs. This article provides an overview of the recent advances and functional applications of biosensing materials for mAb detection. Subsequently, we present the approaches by which mAb receptors are combined with materials to construct stimulus‐responsive analytical platforms that evaluate the contents and activities of mAbs in biological systems, enabling real‐time monitoring and diagnosis that could facilitate administration of mAbs during treatment. Furthermore, the review examines various applications of biosensing for mAb detection and implications in real‐world contexts; it also discusses ongoing challenges and future prospects.
