About

Xiaojun Xian is pioneering the next generation of chemical sensing technologies, with a focus on highly miniaturized, multiplexed systems for mobile health and the Internet of Things. His major contributions lie at the intersection of advanced nanomaterials and semiconductor device engineering. Notably, Xian has demonstrated the first highly sensitive and reversible MXene-based micro quartz tuning fork gas sensors, achieving tunable selectivity by leveraging the unique morphology and metal-like conductivity of MXenes. This work, published in 2024, has already garnered 33 citations, signaling its rapid impact on the field of gas sensing. In parallel, Xian has developed a groundbreaking approach to turn a standard CMOS imager into a multiplexed chemical sensor, a feat that promises to miniaturize and scale chemical detection for integration into mobile devices and robots. This 2022 publication, with 11 citations, showcases his ability to repurpose ubiquitous consumer electronics for advanced analytical chemistry. Through these innovations, Xian is not only advancing fundamental sensor science but also paving the way for practical, deployable sensing platforms that could transform environmental monitoring, healthcare diagnostics, and smart device functionality.
