The sizes of pour and nanoparticles are increased with an increase in implantation dose. Acoustic vibrations generated by laser irradiation in silver nanoparticles of various sizes are registered by low-temperature Raman spectra of composite material....
Our micro-Raman spectroscopic study reveals that hMSCs treated with silver nanoparticles undergo oxidative stress at doping levels in excess of 2 μg/ml, with results of a statistical analysis of Raman spectra suggesting that the induced stress becomes more dominant at nanoparticle concentration levels...
In this paper, we report the high quality low-frequency resonance Raman (RR) spectra of oxyhemoglobin (oxyHb) and its reconstituted analogs, in which proto... Edyta,Podstawka,and,... - 《Journal of Molecular Structure》 被引量: 70发表: 2001年 Optimization of silver nanoparticles for surface...
Further, the Raman spectra of 0D ZnO-immobilized PVDF nanocomposite has been well investigated by Indolia and Gaur in a recent report [82]. Improvement of the crystalline feature of PVDF was witnessed to be increased by the incorporation of ZnO nanoparticles. This refers to the strong ...
The nanoparticles diameters were adjusted from 450 to 1000nm with surface protrusions up to 10-25nm. The growth direction of silver nuclei is controlled by their degree of coating by PVP. The flower-shaped silver nanostructures obtained were used as stable Surface Enhanced Raman Scattering (SERS)...
ZnSe nanoparticles were synthesized by using a thermal evaporation method for a vapour phase reaction of zinc and selenium sources. The sample was characterized by XRD, TEM, HRTEM and Raman spectroscopy. Raman spectra of longitudinal-optical (LO) like mode was analysed by a macroscopic continuum ...
The main purpose of this study is to detect di erent ecologically harmful substances in aqueous solutions using surface enhanced Raman spectroscopy (SERS) as a tool. Therefore, assigning the vibrational modes is essential to identify the substances. SERS using silver nanoparticles was used to obtain...
Surface-enhanced Raman scattering assessment of DNA from leaf tissues adsorbed on silver colloidal nanoparticles In this work, the surface-enhanced Raman scattering (SERS) spectra of seven genomic DNAs from leaves of chrysanthemum (Dendranthema grandiflora Ramat.), co... C.,M.,Muntean,... - 《...
between colloidal silver nanoparticles and silver piece is presented.The Raman signal shows a104enhancement compared to that of bulk GO.The large Raman enhancement is most likely a result of electromagnetic(EM)coupling between the colloidal silver nanoparticles(localized surface plasmon)and the silver ...
silver nanoparticlesSEMTEMAFMWe report a novel method for the fabrication of films of silver nanoparticle aggregates that are strongly attached to Si substrates (Thiol-immobilized silver nanoparticle aggregates or TISNA). The attachment is achieved by chemically modifying the surface of a Si(100) ...
