Nanoscience and nanotechnologies are leading to a major point to our understanding of nature. Nanotechnology can be generally defined as creation and use of nano-sized systems, devices, and structures which have special functions or properties because of their small size. 
This volume on Nanotechnology Applications in Health and Environmental Sciences focuses on biotechnological and environmental applications of nanomaterials. It covers popular and various nanomedical topics such as oncology, genetics, and reconstructive medicine. Additionally, many chapters give leading-edge information on nano-sensor applications and usage in specific disciplines. Also, two chapters on novel subjects have been included on Lantibiotics and microbiota. This book should be useful for nanotechnologists, microbiologists, and researchers interested in nanomedicine and nano-biotechnology, as well as environmental nanotechnology.
