As mentioned in the background section, one advantage that peptides has over carbon as nanosize building blocks is that they have almost limitless chemical functionality compared with the very chemical interactions that carbons can perform due to their nonreactiveness.mino acids are monomer molecules that carries a carboxyl and an amine functional groups; a spectrum of other chemical groups are attached to different amino acids, such as thiols and alcohols. This facilitates the wide range of chemical interactions and therefore molecular recognitions that peptides are capable of.
