Abstract:

Proteins and peptides have been recognized as potential leads for the synthesis of novel therapeutics to treat a variety of human ailments. Unfortunately, therapeutic potential and clinical applications of these biomacromolecules are challenging due to the verge of delivery applications. Nanocarriers offer unique potential to overcome various biological barriers and improve the delivery of therapeutic biomacromolecules like proteins and peptides. A smart nanocarriers-based drug delivery system can be defined as a system that has site-specific drug delivery in a controlled manner against all the physiological barriers and finally metabolized in the body. This review describes various nanocarriers investigated for the delivery of proteins and peptides to augment their clinical applications. Various biological aspects of protein and peptide delivery have been also focused. We also summarized various patents granted for nanocarrier reported to deliver these biomacromolecules followed by a landscape presentation of marketed nano-formulations for protein and peptide delivery.
