Special Issue "Sensing at the Nano-Scale: Chemical and Bio-Sensing"
Deadline for manuscript submissions: closed (15 January 2012).
Interests: chemical sensors; nano-structured oxides; electroceramics; ceramic thick and thin films
Developing novel functional materials and devices with controlled features on the nanometer scale is at the core of R & D innovation. Unique electronic, optical, magnetic, as well as chemical properties of nano-scale materials are making them attractive for new generation of devices. There are evidences that suggest fundamentally new behavior in nanomaterials that otherwise cannot be predicted by simple scaling laws. Semiconducting nanoclusters display interesting optical, electronic and chemical properties, making them potential candidates for biosensors and optoelectronic devices. Also, while conductivity enhancement by several orders of magnitude is seen in some nanocrystalline oxides, improved chemical and photo-chemical activity is evident in other nanostructured oxides because of enhanced surface area. Because of unusual surface properties, materials with nano-scale features are particularly attractive for realizing fast-responding sensors with good sensitivity and selectivity for the detection of chemical species and biological agents. The topics covered in this special issue will represent recent innovations in nano-processing that integrates cutting edge expertise and resources in materials processing, lithographic and non-lithographic approaches in micro- and nano-fabrications, microscopy and other advanced characterization techniques. On the detection side, the focus will be on both the theoretical and experimental aspects of surface and interface chemistry involving gas-solid and liquid-solid reactions, as well as interaction of solid surfaces with biological systems. Both review and original research articles are expected from a broad spectrum of disciplines such as physics, chemistry, biochemistry, medicine, analytical science, environmental science, materials science, electronics, automation, instrumentation and engineering to highlight the latest developments and future challenges in this exciting filed of nano-scale sensing.
