The process of developing biosensors requires fundamental research on plasmonics so that new functionalities can be achieved that are not available with the conventional approaches. In Nanophotonics and Biodetection Systems Laboratory, we utilize nano-plasmonics to develop ultra-sensitive spectroscopy and sensing technologies for real-time, label-free and high-throughput detection and analysis of very low quantities of biomolecules. In order to achieve large sensitivities, high-quality factor plasmonic structures supporting extremely sharp spectral features with strong nearfield responses are explored. The sensing platforms utilizing these plasmonic structures allows stronger analyte-field overlap, which leads strong spectroscopy and sensing signals, easily distinguishable by detectors.


In the conventional spectrometer-based read-out schemes that utilize refractive index sensing, the presence of biomolecules is measured by monitoring spectral shifts within the optical response of the plasmonic structures. These platforms can enable analyte sensing, i.e., viruses or bacteria, from biological media at clinically relevant concentrations with little to no sample preparation. Multiplexing and high-throughput capability of these biosensors can be improved via integrating large scale and highly dense plasmonic chips to imaging based platforms, i.e., CCD or CMOS cameras. These biosensors can be also portable to be employed in the resource-poor settings by integrating plasmonic chip technology with lensfree telemedicine technology. This handheld design can be integrated with portable read-out-devices, e.g., a laptop or a cell-phone, that enables detection of biomolecules with a multiplexed manner in any environment, lack of medical infrastructure. This system can also enable parallel detection of different biomolecules with ultra-thin layers as well as quantitative analyses of single-type biomolecules with large variety of concentrations. We also investigate fluidic systems integrated with plasmonic chip technology for efficient analyte-delivery, yielding ultra-fast sensor response. Integrating microfluidics with plasmonic handheld technology, we also demonstrate real-time analyses of protein-protein interaction kinetics in a cost-effective and high-throughput manner. Utilizing robust and smart algorithms, this microfluidic technology allows to monitor biomolecular binding interactions at pMolar levels.
