Jian Yu | Atomic and Molecular Spectroscopy | Research Excellence Award

Nanchang Hangkong University | China

Dr. Jian Yu is an accomplished materials chemist and Associate Professor in the School of Environmental and Chemical Engineering at Nanchang Hangkong University, China, with a strong research focus on surface-enhanced Raman scattering (SERS) spectroscopy and its applications in environmental monitoring and biosensing. He obtained his Ph.D. in Chemistry from Beihang University in 2020 under the supervision of Prof. Lin Guo, where he developed a solid foundation in nanomaterials synthesis, interfacial charge transfer, and spectroscopic analysis. Following his doctorate, Dr. Yu continued at Beihang University as a postdoctoral researcher from 2020 to 2023, further strengthening his expertise in advanced functional nanomaterials and analytical sensing technologies. Dr. Yu’s research centers on the rational design and controlled construction of high-sensitivity SERS substrates, particularly semiconductor-based and amorphous nanostructured materials. A key innovation of his work lies in engineering photo-induced charge transfer processes to overcome the limitations of traditional noble-metal SERS substrates. Through the development of three-dimensional amorphous molybdenum-based nanocages and amorphous molybdenum sulfide systems, he has achieved ultrahigh Raman enhancement factors of up to 10⁶ and ultra-low detection limits down to 10⁻¹⁰ M. These advances significantly expand the sensitivity, stability, and reproducibility of SERS detection platforms. Dr. Yu has successfully applied these novel SERS systems to a wide range of real-world challenges, including the detection of emerging environmental pollutants, volatile organic compounds (VOCs), and biologically relevant molecules. His work has demonstrated accurate discrimination of tumor cells and sensitive identification of trace-level contaminants, highlighting the strong translational potential of his research in environmental safety, public health, and biomedical diagnostics. His ongoing project on the controlled construction of three-dimensional amorphous molybdenum-based nanocages for SERS detection of emerging pollutants reflects his commitment to addressing pressing environmental issues through innovative spectroscopy technologies.
