Nanocomposites in Electrochemical Sensors

Nanotechnology has become one of the most important fields in science. Nanoparticles exhibit unique chemical, physical and electronic properties that are different from those of bulk materials, due to their small size and better architecture. Nanoparticles can be used to construct novel sensing devices; in particular electrochemical sensors. Electrochemical detection is highly attractive for the monitoring of glucose, cancer cells, cholesterol and infectious diseases. Unique nanocomposite-based films proposed in this book open new doors to the design and fabrication of high-performance electrochemical sensors.

Prof. Sharifah Bee Abd Hamid is the Director of Nanotechnology & Catalysis Research Centre (NANOCAT), a potential National HICOE and UM COE. She completed her DSc in catalysis from University of Namur, Belgium in 1993, whilst MSc in catalysis from UKM (Malaysia) in 1989, and BSc in chemistry from Ohio State University (USA) in 1982. She has unique experience gained from academia and industry. She is a world recognized and respected leader in catalyst and adsorbent with strong proven track record in catalyst and nanomaterial design, petroleum refining and petrochemical processes, oleochemicals, biomass and nanocarbon. She is also a recognized authority in mercury trapping media. Prof. Sharifah has held numerous positions in PETRONAS, Shell, Leverhulme Centre for Innovative Catalysis (United Kingdom), and since 2001 in University of Malaya. Her research interest is in catalysis and nanomaterial. She remains active in catalyst development based on metal oxides, carbon, HPA, Ionic Liquid. Besides petrochemical and environmental caalysis, she focuses her research in biorefining and solar refining with emphasis on technology and catalyst development of sustainable resources from biomass and water, and capitalizing from solar energy. The catalyst and nanomaterial find applications in sustainable energy and chemical synthesis, besides active in water environment mitigation.
