about this item
Nanotechnology is a budding field and has a pivotal role in sensing. Nanomaterials exist in various forms such as nanoparticles, nanoclusters, nanobelts, and nanospheres. These nanomaterials act as sensing interface and immobilization surface for various biomolecules such as enzymes, DNA, antigen, etc. Therefore, preparation and characterization of these nanoparticles play an important role in sensing devices.
This handbook has evolved from the authors’ teaching and research experience in the field of nanoparticle biosensing. It encompasses protocols for synthesis of various forms of metal oxide nanoparticles; study of the various characterizing techniques that help deduce the shape, size, and morphology of these nanoparticles; and applications of these nanoparticles in the field of biosensors. It presents voltammery techniques such as cyclic, linear wave, wave pulse, and differential pulse voltammetry. It throws light on interactions of nanomaterials and biomolecules and discusses microfluidic devices, which due to their unique capability of miniaturization fascinate many researchers. It thus aims to introduce the various basic principles and practical information needed by undergraduate and advanced-level students and researchers to understand the science behind nanoscale sensing.
