The peptide nano-rings containing Au nanoparticles inside their cavities were self-assembled on dithiol SAMs patterned as an array by AFM-based nanolithography. The peptide nano-rings were aligned as a line on these SAMs, and Au formed lines with the spacing between these nanoparticles as the peptide nano-rings functioned as spacers. This type of array fabrication will provide improved tunability in their optical properties of resulting nanoparticle-assembled arrays. In addition, optimization of the inter-particle distance of nanoparticles in the array with various spacers may allow one to design new types of photonic crystals with desired optical properties.

Tetragonal ferroelectric BaTiO3 nanoparticles are hydrolyzed inside peptide-ring templates at room temperature and pressure (see figure). The sizes of the monodisperse BaTiO3 nanoparticles are controlled between 6 and 12 run by varying the cavity size of the nanorings as a function of pH. The nanoparticles possess switching behavior under the influence of external electric fields.

A method to separate peptide nanotubes using size-exclusion columns was reported. Peptide nanotubes were self-assembled from a peptide bolaamphiphile monomers, bis(N-α-amido-glycylglycine)propane-1,3-dicarboxylate, in a pH 4.7 NaOH/citric acid solution (50 × 10-3 M). The straight 1D single chains of 6 nm Au nanoparticles were synthesized using peptide nanotubes with a diameter of 10 nm as templates. It was observed that the length of the 1D single chains of Au nanoparticles could be extended to the order of a few micrometers using longer nanotubes.

... Nanorings are nanoscale circular bands, characterized by varying diameters and thicknesses. Nanorings have been synthesized using both physical (Nuraje et al., 2006;Wu et al., 2016) and chemical synthesis routes Jiang et al., 2004;Kelf et al., 2011;Nuraje et al., 2006). In the chemical realm, Hu et al. used the GRR between silver nanoplates and aqueous HAuCl 4 to form Ag-Au nanorings which were used as colorimetric nanosensors . ...

... Report have been given based on an observation especially from the sample of BiFeO3 particle by [50][51][52] revealed that TCO/ perovskite oxide based crystals exhibit sizedependent characteristics that invariably correlate with increased suppression of spiral spin structure when the particle size is decreased, uncompensated spins and strain anisotropic at the surface. In general, many TCO/perovskite nanoparticles exhibit combined ferromagnetic and ferromagnetic behavior in the same phase with coupling between the two orders indicates that they actually have spontaneous polarization characteristics which can be re-oriented by an applied magnetic field and the other one that can be reoriented by applied magnetic field also These processes often generate magneto-electric memory effects and magnetic switching of ferroelectric domain and again coupled with their high performance in solar energy harnessing .From this it is clearly observed from the foregoing comments that based on high dielectric, ferroelectric, piezoelectric, pyro-electric properties, TCO/perovskite nanocrystal have numerous devices applications that are made from them, such as multilayered ceramic capacitors, ferroelectric memories, [53][54][55][56][57] voltage tunable capacitors, surface acoustic wave devices Infra-red detectors and again their unique performance in high efficiency in solar energy harnessing etc.. These numerous applications associated with them and their wide range of characteristics in the electronic gadgets and instruments have placed any material made from them to be in high demand in this present dispensation, and that is also the more reason why there has been much quest on miniaturization of ferroelectric, magnetoelectric and other associated materials with them [58][59][60][61][62][63][64] in order to achieve the reality of their amenability to these many applications. ...

... For instance, in one synthesis, Gao et al. reported the production of nanotubes with diameters ranging from 10 to 320 nm. 297 Note that differences in the overall tube diameter can be achieved with different batches of the monomer. 297 While such diversity could be useful, the ability to generate Au nanoparticle assemblies using nanotubes of a single diameter could be important for a variety of applications, especially optical/plasmonic capabilities, where forming 1D linear necklace-like assemblies of Au nanoparticles could be especially important. ...
