Adaptive optics allows STED-FCS measurements in the cytoplasm of living cells

Fluorescence correlation spectroscopy in combination with super-resolution stimulated emission depletion microscopy (STED-FCS) is a powerful tool to investigate molecular diffusion with sub-diffraction...

Video-rate multi-color structured illumination microscopy with simultaneous real-time reconstruction

Super-resolved structured illumination microscopy (SR-SIM) is among the fastest fluorescence microscopy techniques capable of surpassing the optical diffraction limit. Current custom-build instruments...

Modal symmetry controlled second-harmonic generation by propagating plasmons

A new concept for second-harmonic generation (SHG) in an optical nanocircuit is proposed. We demonstrate both theoretically and experimentally that the symmetry of an optical mode alone is su_cient to...

Nagetier-assoziierte Zoonoseerreger in Deutschland: Vorkommen, Übertragung und Nachweis

Nagetiere sind in vielerlei Hinsicht mit der menschlichen Zivilisation verbunden. Neben ihrer Rolle als Schädlinge in vielen Bereichen stellen Nagetiere wichtige Reservoire für Zoonoseerreger dar. Zu...

Silver mirror reaction as a simple method for silicon nanowires functionalization

A cheap and facile wet-chemical ‘silver mirror’ reaction approach has been proposed for the silicon nanowires (SiNWs), formed by the metal-assisted wet-chemical etching, decoration with silver nanoparticles...

Nonresonant Raman spectroscopy of isolated human retina samples complying with laser safety regulations for in vivo measurements

Retinal diseases, such as age-related macular degeneration, are leading causes of vision impairment, increasing in incidence worldwide due to an aging society. If diagnosed early, most cases could be prevented....

Genotyping of methicillin-resistant Staphylococcus aureus from sepsis patients in Pakistan and detection of antibodies against staphylococcal virulence factors

In order to obtain more information on the MRSA population structure in the border region of Afghanistan and Pakistan, we collected and genotyped MRSA causing bloodstream infections from a tertiary care...

Light guidance in photonic band gap guiding dual-ring light cages implemented by direct laser writing

Efficient waveguiding inside low refractive index media is of key importance for a great variety of applications that demand strong light–matter interaction on small geometric footprints. Here, we demonstrate...

Raman spectroscopic analysis of microbial gas exchange processes

Counterfeit and substandard test of the antimalarial tablet Riamet® by means of Raman hyperspectral multicomponent analysis

The fight against counterfeit pharmaceuticals is a global issue of utmost importance, as failed medication results in millions of deaths every year. Particularly affected are antimalarial tablets. A very...
