Dr. Muhammad Azhar Hayat Nawaz completed his PhD in Analytical Chemistry from the State Key Laboratory of Electroanalytical Chemistry, Changchun Institute of Applied Chemistry, Chinese Academy of Science, University of Science and Technology of China (USTC). He specializes in the design, synthesis, and functionalization of advanced materials for the development of diverse sensor platforms. His work primarily focuses on creating surface-engineered interfaces by integrating nanostructures such as MOFs, polymer-nanomaterial hybrids, and doped metal oxides onto flexible and planar substrates including paper, screen-printed electrodes, and polymer films. He has developed several disposable and portable sensing systems, emphasizing simplicity, cost-efficiency, and adaptability. His expertise spans across colorimetric, electrochemical, and dual-mode sensor development using engineered surfaces for signal amplification and selective recognition of wide range of analytes.
