Abstract
The utilization of surface plasmon resonance (SPR) sensors for real-time label-free molecular interaction analysis is already being employed in the fields of in vitro diagnostics and biomedicine. However, the widespread application of SPR technology is hindered by its limited detection throughput and high cost. To address this issue, our study introduces a novel multifunctional MetaSPR high-throughput microplate biosensor featuring 3D nanocup microarrays, aiming to achieve high-throughput screening at a reduced cost and with enhanced speed. Different types of MetaSPR sensors and analytical detection methods have been developed for accurate subtype identification, epitope binding, affinity determination, antibody collocation, and other applications that have greatly promoted the screening and analysis of early antibody drugs. The MetaSPR platform combined with nano-enhanced particles amplified the detection signal and improved the detection sensitivity, making it more convenient, sensitive, and efficient than traditional ELISA. Our findings demonstrated that the MetaSPR biosensor is a new practical technology detection platform that can improve the efficiency of biomolecular interaction studies with unlimited potential for new drug development.
