Bolaamphiphile, which is a class of amphiphilic molecules, has a unique structure of two hydrophilic head groups at the ends of the hydrophobic center. Peptidic bolaamphiphiles that employ peptides or amino acids as their hydrophilic groups exhibit unique biochemical activities when they self-organize into supramolecular structures, which are not observed in a single molecule. The self-assembled peptidic bolaamphiphiles hold considerable promise for imitating proteins with biochemical activities, such as specific affinity toward heterogeneous substances, a catalytic activity similar to a metalloenzyme, physicochemical activity from harmonized amino acid segments, and the capability to encapsulate genes like a viral vector. These diverse activities give rise to large research interest in biomaterials engineering, along with the synthesis and characterization of the assembled structures. This review aims to address the recent progress in the applications of peptidic bolaamphiphile assemblies whose densely packed peptide motifs on their surface and their stacked hydrophobic centers exhibit unique protein-like activity and designer functionality, respectively.

“…Amino acid bolaamphiphiles, featuring amino acids as hydrophilic groups at both ends of a hydrophobic center, have been studied as molecular building blocks for constructing protein-analogous scaffolds, functioning similarly to apoenzymes. 1–6 Coordination of various transition metal cofactors with self-assemblies of amino acid bolaamphiphiles yields a series of colloidal supramolecular catalysts, similar to metalloenzymes. 1 For example, Liu and colleagues reported chiral tubular assemblies with copper or dirhodium( ii ) ions, displaying catalytic activity towards enantioselective cycloaddition.…”

A comparative study on surfactant cetyltrimethylammoniumbromide modified clay‐based poly(p‐anisidine) nanocomposites: Synthesis, characterization, optical and electrochemical properties

et al. 2021

The preparation of hybrid materials, namely poly(p-anisidine)@Clay (poly (pAnis)@Clay) and poly(p-anisidine)@cetyltrimethylammoniumbromide-Clay (poly(pAnis)@CTAB-Clay), prepared by oxidative polymerization process is presented. The formation of nanomaterials has been confirmed by XRF, XPS, FT-IR, and UV-Vis spectroscopy. Interestingly, the study of the optical band gap energy (E g) evince lowest value of 3.22 eV for poly(pAnis)@CTAB-Clay compared to poly(pAnis)@Clay with 3.26 eV. XRD results demonstrate that the intercalation of the poly(pAnis) into the Clay was confirmed by the increased interlayer spacing, the exfoliation and intercalation forms were affirmed in the TEM images. In addition, the electrochemical behavior indicates that the prepared nanocomposites are electroactive. These results are heartening in respect with the objective to utilize them in the field of technology and research related to the photovoltaics application.
