Reflectance Modification in Nanostructured Silicon Layers with Gradient Porosity

Asignificant change in effective reflectance spectra of nanostructured porous silicon layers grown with different times of metal-assisted chemical etching is detected. The low reflectances at the level...

Resonance-induced dispersion tuning for tailoring nonsolitonic radiation via nano-films in exposed core fibers

Efficient supercontinuum generation demands for fine-tuning of the dispersion of the underlying waveguide. Resonances introduced into waveguide systems can substantially improve nonlinear dynamics in ultrafast...

Medical needs for translational biophotonics with the focus on Raman-based methods

This report summarizes state-of-the-art biophotonic approaches for unmet needs in medicine with the focus on spontaneous and coherent Raman methods since 2017. Numerous proof-of-principle studies demonstrated...

Molecular characterization of Staphylococcus aureus isolates associated with nasal colonisation and environmental contamination in academic dental clinics

Aim: To determine the genetic makeup of methicillin-sensitive/methicillin-resistant Staphylococcus aureus (MSSA/MRSA) from nasal colonization and environmental contamination in dental clinics. Materials...

Biomimic Vein-Like Transparent Conducting Electrodes with Low Sheet Resistance and Metal Consumption

Resource efficiency is an important issue in our modern society. Our community is facing severe problems with the short supply of critical resources and energy. In this contribution, inspired by the excellent...

Laboratory setup for extreme ultraviolet coherence tomography driven by a high-harmonic source

We present a laboratory beamline dedicated to nanoscale subsurface imaging using extreme ultraviolet coherence tomography (XCT). In this setup, broad-bandwidth extreme ultraviolet (XUV) radiation is generated...

Tuning the Effective PT Phase of Plasmonic Eigenmodes

We experimentally observe an effective PT -phase transition through the exceptional point in a hybrid plasmonic-dielectric waveguide system. Transmission experiments reveal fundamental changes in the underlying...

Highly sensitive detection of the antibiotic ciprofloxacin by means of fiber-enhanced Raman spectroscopy

Sepsis and septic shock exhibit a rapid course and a high fatality rate. Antibiotic treatment is time-critical and precise knowledge of the antibiotic concentration during the patients’ treatment would...

Microwave-assisted synthesis of core-shell nanoparticles – insights into the growth of different geometries

More Favorable Palmitic Acid Over Palmitoleic Acid Modification of Wnt3 Ensures Its Localization and Activity in Plasma Membrane Domains

While the lateral organization of plasma membrane components has been shown to control binding of Wnt ligands to their receptors preferentially in the ordered membrane domains, the role of posttranslational...
