Visible light activated chemoresistive gas sensors
We develop visible light activated chemoresistive gas sensor based on 2D materials and metal oxide nanoparticles. Visible light illumination enables stable room temperature gas sensing and substantially enhances gas sensing performance. Visible light driven chemoresistive gas sensor is anticipated to be further applied in electric nose.
Surface Plasmon Resonance (SPR) sensor research using metal oxide and 2D materials.
Surface Plasmon Resonance (SPR) is a coherent oscillation of the surface conduction electrons excited by electromagnetic radiation. The technique makes it possible to measure interactions in real-time with high sensitivity and without the need for labels. We are conducting research on sensors that detect below ppm level of impurities in various solutions.
Dynamic response taste sensor array using 2D materials and molecular sieves for high selectivity
The molecules of 5 tastes (sour, sweet, saltiness, umami, bitterness) are detected with 2D materials. Metal nanoparticles or molecular sieves are introduced to the 2D materials for high selectivity and sensitivity. The single taste sensor devices are integrated to form a taste sensor array module.
Gas sensors based on two-dimensional(2D) materials
We develop gas sensing devices operating at room temperature based on 2D materials such as graphene and MoS2. In addition, we establish a novel strategy stably define microscale patterns of 2D materials on large-scale flexible substrates. The results enlarge the potential of 2D material-based gas sensors for use in the next-generation electronic devices that are flexible, wearable, and foldable.
