'Nanoscience and technology are regarded as one of the most promising and important filed in the 21st century. One significant reason is that nanomaterials have a large surface area along with an interfacial state; hence, the physiochemical properties of nanomaterials are different from bulk materials. It is well known that size and shape-controlled synthesis is gaining tremendous interest in nanostructure materials research. This book deals with the introduction of nanoscience and technology, the fundamentals of nano biosensor concept, and its applications. The aim of this book is a compilation of both fundamentals and applications aspects for biosensors in agricultural applications, and study materials for young researchers and master students in nanotechnology pertaining to agricultural and food safety applications. The study materials have been compiled within five chapters Read more
