Biosensors
1) Magnetic Levitation-Based Biosensors
Our research explores magnetic levitation (MagLev) as a novel biosensing approach for developing rapid and label-free diagnostic platforms. By leveraging the density-based separation of analytes in a paramagnetic medium, we design systems capable of real-time detection without the need for complex labeling or sample preparation. We integrate MagLev technology with optical and smartphone-based readouts to create cost-effective, portable tools for point-of-care diagnostics, pathogen detection, and biomarker monitoring. Through this work, we aim to expand the accessibility and versatility of next-generation biosensing technologies.
2) Plasmonic and Optical Biosensors
We focus on the development of plasmonic and optical biosensors that offer high sensitivity, rapid detection, and label-free analysis for a wide range of biological targets. By utilizing spectrophotometry, we design compact and highly responsive sensing platforms. Our work emphasizes material engineering, surface functionalization, and signal amplification strategies to improve sensitivity and specificity. These optical systems are tailored for point-of-care diagnostics, real-time biomarker monitoring, and integration into miniaturized lab-on-a-chip devices.
3) Microfluidic and Paper-Based Analytical Devices
Our lab develops microfluidic and paper-based analytical devices as low-cost, portable platforms for rapid diagnostics and environmental monitoring. We design patterned paper substrates that enable fluid manipulation without the need for external equipment. By integrating colorimetric and optical readouts, we create user-friendly devices capable of detecting a wide range of analytes, including biomarkers, pathogens, and small molecules. These platforms are particularly suited for point-of-care testing, resource-limited settings, and on-site analysis.
4) Nanomaterials in Biosensing
We investigate the use of functional nanomaterials to enhance the sensitivity, selectivity, and versatility of biosensing platforms. Our work focuses on the synthesis and surface modification of nanoparticles, such as gold and silver nanoparticles, for signal amplification and targeted biomolecular recognition. By integrating these nanomaterials into optical and colorimetric sensor systems, we aim to improve detection limits and selectivity. Through this approach, we contribute to the development of advanced biosensors for early disease diagnosis, environmental monitoring, and point-of-care applications.
