Three dimensional spatiotemporal nano-scale position retrieval of the confined diffusion of nanoobjects inside optofluidic microstructured fibers

Understanding the dynamics of single nano-scale species at high spatiotemporal resolution is of utmost importance within fields such as bioanalytics or microrheology. Here we introduce the concept of axial...

Simultaneous Measurement of Temperature and Refractive Index Using an Exposed Core Microstructured Optical Fiber

We have demonstrated a novel scheme for simultaneous measurement of temperature and refractive index by using an exposed core microstructured optical fiber (ECF). The ECF allows for high sensitivity to...

Spatial proteomics revealed a CX3CL1-dependent crosstalk between the urothelium and relocated macrophages through IL-6 during an acute bacterial infection in the urinary bladder

The urothelium of the urinary bladder represents the first line of defense. However, uropathogenic E. coli (UPEC) damage the urothelium and cause acute bacterial infection. Here, we demonstrate the crosstalk...

Influence of process parameters on the incorporation of phosphorus into silica soot material during MCVD process

The incorporation of phosphorus into silica soot material strongly changes during the multistep preparation process of the MCVD technology in combination with solution doping for Al and rare earths. We...

Nanofiber-based high-Q microresonator for cryogenic applications

We demonstrate a cryo-compatible, fully fiber-integrated, alignment-free optical microresonator. The compatibility with low temperatures expands its possible applications to the wide field of solid-state...

Disturbing-Free Determination of Yeast Concentration in DIWater and in Glucose Using Impedance Biochips

Deionized water and glucose without yeast and with yeast (Saccharomyces cerevisiae) of optical density OD600 that ranges from 4 to 16 has been put in the ring electrode region of six different types of...

Structures for surface enhanced non-plasmonic or hybrid spectroscopy

Absorption, scattering, and fluorescence are processes that increase with electric field intensity. The most prominent way to enhance electric field intensity is to use localized or propagating surface...

Simple differentiation of Salmonella Typhi, Paratyphi, and Choleraesuis from Salmonella spp. using the eazyplex® TyphiTyper LAMP assay

Optical properties of ytterbium/aluminium doped silica glasses

Several series of preform and fiber samples of Yb2O3-Al2O3-SiO2 glass with finelygraded composition steps were prepared by MCVD and solution doping under well-defined conditions. Their optical properties,...

Real-time observation of the optical Sagnac effect in ultrafast bidirectional fibre lasers

The optical Sagnac effect sets fundamentals of the operating principle for ring laser and fiber optic gyroscopes, which are preferred instruments for inertial guidance systems, seismology, and geodesy....
