Optical nanomaterials are next-generation materials with enormous potential to transform health care by providing advanced sensors, imaging devices, and therapies. Nowadays, optical sensor technology has become increasingly crucial in environmental sensing, medical research, and clinical diagnostics. Optical sensors are capable of directly detecting low surface coverage of smaller analyte molecules from different solutions. However, existing optical biosensor technologies still require essential innovation and improvement to deliver high sensitivity, specificity, and diffusion-limited transport. To address these concerns, new sensing platforms with enhanced sensitivity and selectivity are needed. Therefore, to overcome the limits of optical sensing with traditional materials, research in advanced optical materials has intensified in the recent years.

In this webinar hosted by the Environmental Sensing Technical Group, Sreekanth Kandammathe Valiyaveedu a research scientist from the Institute of Materials Research and Engineering at A*STAR will highlight the recent advances in optical nanomaterial-based biosensor technology for future sensing applications. This includes sensors using different sensing mechanisms, nanophotonic platforms and interrogation schemes. The webinar will also discuss reconfigurable sensing using tunable optical material-based sensors and intelligent sensing based on deep learning and artificial intelligence. In addition, optical detection using nanomaterials offers advantages including multiplexing capability, photostability, naked-eye reading, and the ease of miniaturization without sophisticated sensor- chip fabrication.
