In recent years, biosensors have emerged as promising detection tools for detecting disease biomarkers, monitoring environmental pollutants, and ensuring food safety. Among different types of biosensors, optical biosensors based on plasmonic nanostructures, such as Localized Surface Plasmon Resonance (LSPR) and Surface Enhanced Raman Spectroscopy (SERS), stand out due to their simple fabrication methods, minimal sample requirements, and real-time analysis.

This presentation initially explores the fabrication of LSPR-based biosensing platform by synthesizing different sizes and shapes of plasmonic nanoparticles (typically gold) and studying their bulk refractive index sensitivities. By varying the size and shape of these nanoparticles, fine-tuning the sensitivity of the LSPR-based sensors becomes possible, which holds significant promise for biomedical applications. In this talk, the performance of the LSPR sensor chip will be illustrated for detecting cardiovascular disease biomarkers.

Furthermore, the presentation will address future research prospects, focusing on another significant detection technique, SERS, to further enhance the detection sensitivity, emphasising environmentally friendly and cost-effective substrates for food safety monitoring and pesticide detection.
