Xiao Huang received her bachelor degree at the School of Materials Science and Engineering of Nanyang Technological University in Singapore in 2006. At the same university, she completed her PhD under the supervision of Professor Hua Zhang and Professor Freddy Boey in 2011. After that, she worked as a postdoctoral fellow in the same group. She is now a professor at the Institute of Advanced Materials of Nanjing Tech University in China. She has published over 70 papers, such as in Nature Communications, Chemical Society Reviews, Advanced Materials and so on, with a citation of over 8000 times and an h-index of 37. Her current research interest includes the synthesis and application of nanomaterial-based hybrid structures for sensing applications.
Development of gas sensors for detection of volatile organic compounds (VOCs) are important in the non-invasive diagnosis of diseases based on breath analysis [1,2]. Exploration of novel sensory materials is the key to realization of highly sensitive and selective detection of VOCs . Nanostructured materials, including inorganic and organic crystals, offer promising sensing platforms for effective VOC detection . For example, two dimensional (2D) materials such as graphene and transition metal dichalcogenide nanosheets have received tremendous attention in the past decade, and found wide applications in sensing various chemical and biological species [4,5]. Their properties are found to be highly dependent on their morphology, crystal structure, composition, surface chemistry and so on . In this presentation, I will introduce our recent efforts on the development of chemiresistive sensors based on 2D materials and/or their hybrids with porous organic crystals for VOC detection.
