The peptide is one of the commonest materials in nature. Peptides with the specific sequence form certain assemblies like spheres, fibers, micelles and cylinders, etc. So, many research groups have studied on peptide self-assemblies to use them for several biomedical applications. The delicate shape control of peptide assembly is quite difficult, and several conditions such as carbon tail at the end of peptide sequence, long peptide sequence, long reaction time and high temperature are demanded to achieve it. Here, we report the gold nanoparticles conjugated peptide self-assembled nanostructures based on the short peptide sequence and simple assembling conditions including short reaction time and low temperature. The structures of gold nanoparticle conjugated peptide self-assembled nanostructure were confirmed by TEM and UV/Vis spectroscopy. Finally, we applied them to LSPR application to PSA detection at different concentrations for the further studies. |
