Self-assembling peptides in Dentistry Peptide assembly is a fundamental process where short chains of amino acids spontaneously organize into ordered nanostructures. This self-assembly capability makes peptides powerful building blocks for creating a wide array of functional materials, from biomimetic tissues to advanced drug delivery systems. Understanding the principles behind peptide assembly is crucial for harnessing their potential in materials science and beyond.
At its core, peptide self-assembly is driven by non-covalent interactions between amino acid residues. These interactions, including hydrogen bonding, electrostatic forces, hydrophobic effects, and pi-pi stacking, guide the peptides to arrange themselves into specific, often hierarchical, structures. The sequence and structure of a peptide play a critical role in dictating the type of assembly that occursPeptide Self‐Assembly and Engineering. For instance, peptides can form micelles, tubes, particles, fibers, and hydrogels, each with distinct properties and potential applications.
