“…7,8 Yao et al 6,[9][10][11] have synthesized a series of organic nanoparticles by the reprecipitation method and organic nanotubes by the immersing technique using porous alumina membranes as the template, 12 such as, 1,3-diphenyl-5-(2-anthryl)-2-pyrazoline (DAP), 9 1-phenyl-3-((dimethylamino) styryl)-5-((dimethylamino)phenyl)-2-pyrazoline (PDDP), 6 1,3-diphenyl-2-pyrazoline (DP), 10 1,3-diphenyl-5-pyrenyl-2-pyrazoline (DPP) nanoparticles 11 and R-di-2-naphthyl prolinol (DNP) nanotubes. 12 They suggested that the organic nanoparticles also possess significant quantum size effects resembling those of inorganic semiconductors and metals. Jang et al 5 have prepared dye-conducting polymer core-shell composite nanoparticles (pyrene-polypyrrole) using microemulsion micelles as nanoreactors.…”

Tris-(8-quinolinolato) aluminum (AlQ 3 ) organic nanoparticles with an average diameter 20 nm were prepared through a reprecipitation method. The AlQ 3 nanoparticles are spherical and the average particle size does not change by varying the aging time. The photoluminescent and electroluminescent properties were investigated via the AlQ 3 nanoparticles and the device based on the AlQ 3 nanoparticles, respectively. Blue shift of both the photoluminescence and electroluminescence spectra for the AlQ 3 nanoparticles was observed. With increasing the driving bias, the maximum EL emission peak of the AlQ 3 nanoparticles was shifted to longer wavelength. The maximum luminance and luminous efficiency of the AlQ 3 nanoparticle-based device are about 600 cd/m 2 at driving bias 16Vand 0.19 cd/A at a current density of 150 mA/cm 2 , respectively. The obvious quantum size effect of electro-luminescence devices with the AlQ 3 nanoparticles has been proved, which will open a useful route and new studying field of organic electronic devices, and the study of the fundamental process connecting both of those more conventional classes of materials, i.e., organic molecular crystals.

“…In the past decades, carbon nanotubes 1 as well as other kinds of nanotubes composed of inorganic compounds, [2][3][4][5] or organic polymers [6][7][8][9] have been synthesized. And subsequently biofunctionalized nanotubes have been particularly focused on because of their potential applications to biosensors, [10][11][12] bioseparations and biocatalysis.…”

The protein nanotubes fabricated by a layer-by-layer deposition method using the porous alumina membrane as the template were described. The combination of the template method and the layer-by-layer assembly technique for the fabrication of protein nanotubes presented simplicity and versatility. The nanotubes composed of two kinds of proteins (bovine serum albumin and hemoglobin lyophilized bovine erythrocytes) with different sizes could be synthesized through this method. The outside diameter of the obtained nanotubes was determined by the diameter of the pores of the template. And the wall thickness of the protein nanotubes increased with the increase of the number of protein layers that made up of the walls of nanotubes. Such biodegradable nanotubes with good biocompatibility should be useful for in vivo applications.

“…We have achieved high‐quality SERS spectra of the chiral molecule ( R )‐di‐2‐naphthylprolinol (DNP) on the Ag‐NP‐modified Ag electrode, using an ultradilute solution at a concentration of 10 −12 M . It should be mentioned that DNP is an interesting molecule whose intramolecular interactions of the π–π type or the hydrogen bonds may induce a change of the dihedral angle between the two naphthalene rings in the molecule12, 13 and hence might affect the chirality of the molecule to a certain degree 14…”

The applicability of surface-enhanced Raman spectroscopy is demonstrated to probe the adsorption behavior of individual molecules on a Ag electrode. High-quality SERS spectra of (R)-di-2-naphthylprolinol (DNP) were obtained from ultradilute solutions (10 −12 M) on the Ag-nanoparticle-modified Ag electrode, which is attributed to the high electromagnetic (EM) effect of the SERS-active system as well as to the strong adsorption and interaction of DNP molecules with Ag. The stable SERS spectra present remarkable potential dependence, which gives evidence for the behavior of individual DNP molecules on the Ag surface. Based on statistical analysis for the probability of DNP molecules located in 'hot spots', we propose an SERS mechanism for individual molecules in the electrode system, in combination with the hot-spot model and orientation of the probe molecules.
