Book excerpt: De novo Peptide Design: Principles and Applications presents the latest developments in the fields of therapeutic peptides and bio-nanotechnology. The title focuses on the design of peptides, particularly how peptides may be tailored to specific functions. It includes computational and experimental protocols to assist in the design of peptides. Sections cover the basics of protein and peptide structure, modeling and simulation, solid phase peptide synthesis, peptide-based antibiotics, drug delivery, peptide nanomaterials, aromatic interactions directing nano-assembly, protein/peptide aggregation, therapeutic interventions against protein/peptide aggregation diseases, peptide based hydrogels, computational tools and algorithms for peptide design, and experimental protocols in peptide chemistry. In addition, the book covers key aspects in peptide design, providing a solution for researchers working within the 'peptidic universe' to create new therapeutic agents. - Gives comprehensive coverage, including peptide design, modeling, synthesis and applications - Presents emerging topics in the design of peptide-based therapeutics - Details the latest developments in the fields of therapeutic peptides and bio-nanotechnology - Considers peptide design and the tailoring of peptides to specific functions - Offers computational tools and algorithms for peptide design and experimental protocols for peptide chemistry
