Fabrication and synthesis of plasmonic structures is rapidly moving towards sub-nanometer accuracy in control over shape and inter-particle distance. This holds the promise for developing device components based on novel, non-classical electro-optical effects. Monochromated electron energy-loss spectroscopy (EELS) has in recent years demonstrated its value as a qualitative experimental techniqu...

Atomic-scale charge transport properties are not only of significant fundamental interest but also highly relevant for numerous technical applications. However, experimental methods which capable detecting at the single-digit nanometer length scales scarce. Here we report on molecular nanoprobe (MONA) experiments Pd(110) where utilize carrier-driven switching a single cis-2-butene molecule to d...

gold preparations are one of the oldest disease modifying drugs in the treatment of rheumatoid arthritis. this are different reports about the effects and complications of these compoumis. these opposite reports may he due to the difference in genetic ami ethnic background of patients. this study was designed to evaluate our results in gold therapy ami compare them with those of western countri...

Persistent luminescence nanoparticles (PLNPs) hold great promise for the detection and imaging of biomolecules. Herein, we have demonstrated a novel nanoprobe, based on the manganese dioxide (MnO2 )-modified PLNPs, that can detect and image glutathione in living cells and in vivo. The persistent luminescence of the PLNPs can be efficiently quenched by the MnO2 nanosheets. In the presence of glu...

In single particle imaging applications, the number of photons detected from the fluorescent label plays a crucial role in the quantitative analysis of the acquired data. For example, in tracking experiments the localization accuracy of the labeled entity can be improved by collecting more photons from the labeled entity. Here, we report the development of dual objective multifocal plane micros...

introduction application of near-infrared absorbing nanostructures can induce hyperthermia, in addition to providing more efficient  photothermal effects. gold-gold sulfide (ggs) is considered as one of these nanostructures. this study was performed on a tissue-equivalent optical-thermal phantom to determine the temperature profile in the presence and absence of ggs and millisecond pulses of a ...
