dc.description.abstractMolecular self-assembly is a powerful tool for the generation of functional nanostructures in a bottom-up fabrication. Peptides have drawn significant attention to be used as basic building blocks for such hierarchical assemblies. Diversification of chain stereochemistry offers tremendous increase in the peptide and protein design space. The use of D-amino acids in the peptide sequence can possibly help in accessing the otherwise “forbidden” region of the Ramachandran map for the generation of novel functional peptide sequences composed of L and D amino acids. In this thesis, we have de novo designed different sets of peptide molecules for four different application fronts. In the first project, we have designed a 30 amino acid long artificial blue fluorescent protein by impregnating an unnatural amino acid in the hydrophobic core of an altogether novel fold, which gives blue fluorescence. In the second project, we have designed syndiotactic hexamer peptide (Ff)3-OH, which folds into a gramicidin helical architecture, facilitating an extended phenylalanine network forming quantum confinement. In the third project, we have synthesized Fmoc conjugated ultra-short peptide hydrogels, with interesting self-healing property, which make them potential candidates for tissue engineering and drug delivery. The antimicrobial property of the synthesized peptide hydrogel has been verified against Gram-positive and Gram-negative bacteria.
