Carbon Nanomaterials: Applications in Physico-chemical Systemsand Biosystems

Abstract

In the present article, various forms of carbon and carbon nanomaterials (CNMs) and a new approach to classify them on the basis of sp2-sp3 configuration are presented. Utilising the concept of junction formation (like p:n junction) a concept is developed to explain the special reactivity of nanosized carbon materials. Geometric consideration of chiral and achiral symmetry of single-walled carbon nanotubes is presented which is also responsible for manifesting special propertiesof carbon nanotubes. A brief introduction to various common synthesis techniques of CNMs is given. These is increased chemical and biological activities have resulted in many engineer ednanoparticles, which are being designed for specific purposes, including diagnostic or the rapeuticmedical uses and environmental remediation.
