  • An Innovative Sub-Micron Dielectric Sensing Architecture for Electrochemical Biosensor Application

    Prof. Chih-Ting Lin

    National Taiwan University, Taiwan

    Abstract Biography
    Rapid evolutions of biosensing technologies promote a paradigm shift, i.e., moving diagnostics and monitoring from centralized laboratories to point-of-care settings, in healthcare infrastructures. As this emerging technology growing, the biosensing technology drives a multi-billion-dollar market across different domains, such as clinical diagnostics, environmental monitoring, and personalized medicine. However, quite a few challenges, such as sensitivity, selectivity, repeatability, and stability, block implementations toward clinical applications. There are many researchers devote themselves in developing innovative technologies to address these challenges. In this talk, a newly developed device structure for electrochemical biosensing technologies will be introduced. Different from traditional micro-electrochemical sensing device, the surface-potential change of dielectrics can be measured by electrochemical capacitive measurement with submicron spacing between electrodes. As a consequence, surface modifications and biomolecular-binding events can be monitored by the developed device structure. This proposed sensing mechanism is validated by both simulations and experiments. Based on these validations and its compatibility with existing sensing designs, the developed biosensing architecture can be a straightforward and rapid detection technology with potential applications across a wide range of clinical diagnostics.

  • Implantable Materials and Devices for Chemical Sensing
    and Stimulation in the Brain

    Prof. Xing Sheng

    Tsinghua University, China

    Abstract Biography
    Bio-integrated high performance inorganic optoelectronic devices will provide new insights on interactions between light and bio-systems. Here we present unconventional strategies to design and fabricate microscale, thin-film optoelectronics devices including micro-LEDs and photodetectors that can be formed via epitaxial liftoff and transfer printing techniques. These microscale devices can be heterogeneously integrated on flexible and stretchable substrates and interact with biological systems for biomedical applications. In particular, we produce multifunctional neural probes that can be directly implanted into the deep brain of freely moving animals, modulating and detecting chemical and physical signals in the brain tissue. These photonic implants interrogate the nervous systems, providing insights for fundamental neuroscience studies and promises for medical applications.

  • LAPS-based chemical imaging and applications

    Prof. Tatsuo Yoshinobu

    Tohoku University, Japan

    Abstract Biography
    The light-addressable potentiometric sensor (LAPS) is a semiconductor-based chemical sensor that offers several advantageous features. Its simple structure, consisting of a semiconductor substrate coated with an insulating layer, allows for low-cost fabrication and scalability. The flat, uniform surface of the insulating layer serves as a versatile platform for integrating various sensing functions, such as pH, ion, and biosensing. As a field-effect sensor, LAPS detects surface potential changes in a manner analogous to the ion-sensitive field-effect transistor (ISFET). Whereas the drain current responds to the surface potential changes in an ISFET, LAPS utilizes a photocurrent induced by local illumination, enabling its defining feature: light-addressability. By scanning a focused light beam across the sensor plate, spatially resolved measurements can be achieved. In this talk, I would like to introduce advancements that have been made to enhance imaging performance, particularly regarding spatial and temporal resolution, as well as various applications ranging from biological samples and corrosion studies to microfluidic devices.

    Tatsuo Yoshinobu was born in Kyoto, Japan, in 1964. He received his B.E., M.E., and Ph.D. degrees in electrical engineering from Kyoto University in 1987, 1989, and 1992, respectively, focusing on gas source molecular beam epitaxy of semiconductor silicon carbide. In 1992, he joined the Institute of Scientific and Industrial Research at Osaka University, where he began developing silicon-based chemical sensor devices. From 1999 to 2000, he served as a guest scientist at the Institute of Thin Films and Interfaces, Research Centre Jülich, Germany. Since 2005, he has been a Professor of Biomedical Electronics in the Department of Electronic Engineering at Tohoku University, Sendai, Japan. Since 2008, he has also held a professorship in Biosensing at the Graduate School of Biomedical Engineering, Tohoku University. His research interests center on the development of chemical imaging systems based on light-addressable potentiometric sensors (LAPS) and their diverse applications.

    Material Design for Achieving Both Ultra-High Sensitivity and
    Super Selectivity in Metal Oxide Semiconductor Gas Sensors

    Prof. Emeritus, Kengo Shimanoe

    Kyushu University, Japan

    Abstract Biography
    Semiconductor gas sensors originated in the 1950s from the pioneering work of Prof. Tetsuro Seiyama at Kyushu University, who established a link between the electrical properties of materials and catalytic reactions. Early gas sensors based on iron oxide and ZnO were subsequently reported. From around 2000, significant attention was directed toward MEMS-based devices; however, Prof. Seiyama had already emphasized the importance of thin-film formation and miniaturization from the outset. In particular, thin-film design was based on the concept of “capturing reactions throughout the entire sensing layer.” In recent years, it has been demonstrated that high sensitivity can also be achieved in thick films through the introduction of porosity. Meanwhile, miniaturization has primarily aimed at reducing power consumption, forming the basis of modern high-performance sensors.
    In our research group, we have developed porous thin-film sensors capable of ppb-level detection through material design based on three key factors: receptor function, transducer function, and utility factor. Furthermore, by employing a double-pulse driving method with MEMS devices and controlling surface oxygen adsorption, we have achieved ultra-high sensitivity detection of toluene at the ppt level (7 ppt) by using Pd-loaded SnO2.
    In addition, to enhance selectivity, we focused on the reaction characteristics of metal oxide catalysts. By introducing acidic oxides such as MoO3 and WO3 as receptor materials to SnO2, we succeeded in increasing the sensitivity to ethanol to several tens of times higher than that to methanol. Further improvements in selectivity have also been confirmed through the addition of noble metals such as Pd and Au.
    In this presentation, based on these results, we will discuss strategies for achieving ultra-high sensitivity, super selectivity, and miniaturization in semiconductor gas sensors through advanced materials design.

    Field of Expertise: Gas sensors using metal oxides semiconductors and solid electrolytes, air batteries, oxygen separation membrane using perovskite oxides.
