Single molecule Raman detection of enkephalin on silver colloidal particles

Enkephalin, an endogeneous substance in the human brain showing morphine-like biological functions, has been detected at the single molecule level based on the surface-enhanced Raman signal of the ring breathing mode of phenylalanine, which is one building block of the molecule. For enhancing the Raman signal the enkephalin molecules have been attached to silver colloidal cluster structures. Th...

Far-infrared Absorption by Small Particles

Detailed far-infrared (FIR) and mid-infrared (MIR) studies of aluminum small particles have been carried out. MIR absorption studies of clustered and non-clustered samples suggest that the anomalous FIR absorption does not arise from the clustering together of the individual metallic particles. The MIR absorption, which is too small to be the continuation of the anomalous FIR absorption, could ...

Effect of Substrate Optical Absorption on Surface-Enhanced Raman Spectrometry on Colloidal Silver

Quantitative analytical applications of surface-enhanced Raman spectrometry (SERS) on colloidal substrates are hindered by the experimental difficulties in measuring intensities with precision comparable to that of state-of-theart spectrochemical techniques. Several factors, both adsorbateand substrate-dependent, contribute to the poor reproducibility of SERS. Since the observed enhancement fac...

Effect of colloidal silver nanoparticles and silver nitrate on hematological indices of Zayandehrud Chub (Petroleuciscus esfahani)

Effects of different concentrations of silver nanoparticles and silver nitrate on some hematological indices of Zayanderud Chub (Petroleuciscus esfahani) were investigated. One hundred individuals of the fish (average weight 26.4 ± 1.3 g) were divided into 5 experimental groups, exposed to 1 or 25 µg/L of silver nano or silver nitrate or unpolluted water as control for 10 days. At the end, prim...

Polymer adsorption on colloidal particles

2014 We consider the adsorption of polymers on colloidal particles 2014 spheres and cylinders 2014 whose dimensions are comparable to solution polymer radii of gyration. Adsorption occurs if the « sticking energy » per monomer exceeds a certain threshold. For a colloidal particle, this threshold increases by an amount inversely proportional to its radius. In addition, the repulsive interactions...
