The text book discussed the design, synthesis, characterization, conformational analysis, self-association of small peptides using coded and/or non-coded amino acids. The book also explored different supramolecular gels and the materials properties of short peptides. The book will be useful to chemistry, biotechnology, spectroscopy and material science students at undergraduate and graduate level. The book will be also helpful for researchers in academia and industry who are working with foldamers, hybrid peptides and peptide mimetic, gel.
