By a News Reporter-Staff News Editor at Life Science Weekly -- Researchers detail new data in Fullerenes. According to news reporting from Kaifeng, People's Republic of China, by NewsRx journalists, research stated, "Single-walled carbon nanotube (SWCNT) is one of the most popular low-dimensional carbon materials in material science, nanomedicine, and nanoscale electronics. Yet the application of the SWCNTs was hindered by the self-aggregation."
The news correspondents obtained a quote from the research from Henan University, "To purify and disperse the SWCNTs, non-covalent wrapping is one of the effective options to overcome such defects. In this work, two kinds of short peptides were designed to facilitate the modification of large-diameter SWCNT. The design of the peptide was carried out in a stepwise manner. The effective residues of helix-rich and sheet-rich proteins on SWCNT were studied at the first step, and then a coarse model peptide composed of the key adsorption residues above was built to investigate the adsorption dynamics on SWCNT. In the end, the residues include long alkyl side chain and that include aromatic rings were found to play key roles on the adsorption of protein/peptide on hydrophobic SWCNT. And two peptides rich in the long alkyl chain and aromatic rings were constructed respectively."
According to the news reporters, the research concluded: "The predominant adsorption capabilities of the two kinds of peptides were discerned by the adsorption details."
