Nonlinear absorption in single LaF3 and MgF2 layers at 193 nm measured by surface sensitive laser induced deflection technique

We report nonlinear absorption data of LaF3 and MgF2 single layers at 193 nm. A highly surface sensitive measurement strategy of the laser induced deflection technique is introduced and applied to measure...

Spectrally resolved cavity ring down measurement of high reflectivity mirrors using a supercontinuum laser source

We investigate a cavity ring down setup that offers the possibility to measure the spectrally resolved reflectivities of high reflectivity mirrors. The setup consists of a resonator (ring down cavity)...

Probing Liquid-Liquid Interfaces with Spatially Resolved NMR Spectroscopy

En route to nanometer resolution: Spatially resolved NMR spectroscopy is used to directly probe liquid–liquid interfaces with exceptionally high spatial resolution in one selected dimension. The novel...

Transparent Silver Microcrystals: Synthesis and Application for Nanoscale Analysis

Micrometer-sized atomically flat silver nanoplates with a thickness of 10-20 nm were obtained in a one-pot reduction of silver nitrate with hydrazine sulfate without surfactants or polymers. The optically...

Flexible Biochips for Detection of Biomolecules

Miniaturization of biosensors is envisaged by the development of biochips consisting of parallel microarray patterns of binding sites on rigid substrates, such as glass or silicon. Thin plastic substrates...

Characterization of iron oxide nanoparticles adsorbed with cisplatin for biomedical applications

The aim of this study was to characterize the behaviour of cisplatin adsorbed magnetic nanoparticles (cis-MNPs) for minimal invasive cancer treatments in preliminary in vitro investigations. Cisplatin...

Synthesis and Photophysical Properties of 3,8-Disubstituted 1,10-Phenanthrolines and Their Ruthenium(II) Complexes

The palladium-catalysed cross-coupling reaction between 3,8-dibromo-1,10-phenanthroline with phenylacetylene or 3,5-bis(trifluoromethyl)phenylboronic acid gives good yields of the 3,8-disubstituted products....

Analysis of the multifilament core fiber using the effective index theory

Micro-Raman Detection of Nuclear Membrane Lipid Fluctuations in Senescent Epithelial Breast Cancer Cells

Originally identified in cultured cells, oncogenic cellular senescence is a growth-arrest mechanism which may inhibit tumor development by limiting the ability of cells to divide. However, literature shows...

Doubly resonant optical nanoantenna arrays for polarization resolved measurements of surface-enhanced Raman scattering

We report that rhomb-shaped metal nanoantenna arrays support multiple plasmonic resonances, making them favorable bio-sensing substrates. Besides the two localized plasmonic dipole modes associated with...
