Advanced Sensor Technology to Realize Biochemical Informatics

                Our team is committed to tackling the multifaceted challenges inherent in conventional analytics, diagnostics, and therapeutics by employing state-of-the-art sensor engineering and nanotechnology. As sensor engineering specialists, our mission is to bridge the significant gap between existing biochemical sensor systems and real-world monitoring. Our ultimate goal is to introduce innovative analytical tools and scientific insights to society, built upon the foundation of diverse and multivariate data. 

                To fulfill these objectives, we explore scientific questions that what optoelectronic material, instrumental, and data analytic interfaces can be combined to a powerful sensor system. This investigative methodology is designed to capitalize on the capabilities of nanotechnology and AI to fundamentally transform the operational principles of biochemical sensor systems. Our research scope encompasses all elements of this system, including the design and synthesis of transducers, signal transduction, device fabrication, hardware interfacing, library screening, and data analysis. Through our endeavors, we aim to make this innovative sensor system not only more widely available, but also more user-friendly and easily accessible.
