Quasi-linearly polarized hybrid modes in tapered and metal-coated tips with circular apertures: understanding the functionality of aperture tips

In this study, we investigate analytically and experimentally the roles of quasi-linearly polarized (LP),hybrid, plasmonic and photonic modes in optical detection and excitation with aperture tips in scanning...

A standardized in vitro blood-brain barrier model for studying nanocarrier transport at biological barriers

European Superconductivity News Forum

The sensor, called herein GHS, is based on a dc SQUID connected to a SQIF that amplifies the voltage from the first stage SQUID. The SQIF consists of an array of SQUIDs with various inductances, facilitating...

Raman and infrared spectroscopy differentiate senescent from proliferating cells in a human dermal fibroblast 3D skin model

Senescent cells contribute to tissue aging and dysfunction. Therefore, detecting senescent cells in skin is of interest for skin tumor diagnostics and therapy. Here, we studied the transition into senescence...

Anti-biofilm strategies of amorphous and crystalline pure titanium dioxide nanoparticles: an overview

Microbes often form surface attached communities called biofilms mainly to get protected against antimicrobials and other environmental stresses. This is a major problem in medical, environmental and industrial...

Permanent structural anisotropy in a hybrid fiber optical waveguide

The shearing of a liquid with one-dimensional molecular structure causes structural anisotropy through chain orientation. Here, we exploit this behavior to generate a hybrid fiber optical waveguide with...

Guiding light in a water core all-solid cladding photonic band gap fiber – an innovative platform for fiber-based optofluidics

We present a single-channel photonic band gap fiber design allowing for guiding light inside a water core, which is surrounded by solid microstructured cladding, consisting of an array of high refractive...

SQUID based receivers for electromagnetic exploration

Some exploration targets, mostly the ones with long time constants in Time Domain Electromagnetics (TEM), are easier to detect by measuring the magnetic field instead of its time derivative. As a consequence,...

New developments in magnetic gradiometry

Vector magnetometry in surveys for mineral exploration remains a challenge even with the highly sensitive magnetic field sensors that are currently available. Highly sensitive magnetometers such as Superconducting...

Raman spectroscopy for the analysis of food quality at the producer site of the food chain

The development of different lab-synthesized food related chemicals (e.g. artificial sweeteners or food dyes) that can replace naturally occurring additives, reducing the total price of food production...
