The chapters of the book will basically rely on 'Biofibers'. It will grab the opportunity to embrace the various diversified aspects of the same such as various facets of extraction, treatment, and application of biofibers, methods and technology involved in it, the biological study of the composition and structure of biofibers, its use as alternatives to synthetic polymers, as an upcoming boon to reduce the environmental risks, the evaluatory study of the biofibers using modern technology, analysis of the chemical structure, properties and composition of biofibers. It also reveals the use of biofibers as reactors, catalysts and variegated chemical reactions related to it along with examining and establishing the structural aspect of detecting unknown molecules in biofibers and grafting of biofibers.
