Superferromagnetic Disk Particles for Magnetic Particle Imaging

Small Methods
Abstract Magnetic particle imaging (MPI) offers rapid, highly sensitive tracer‐based imaging without ionizing radiation, but its clinical translation remains challenged by the limited performance of existing superparamagnetic (SP) tracers. In this work, precisely engineered disk‐shaped nanoparticles fabricated from superferromagnetic (

Early-time velocity autocorrelation for charged particles diffusion and drift in static magnetic turbulence

, 2012
Using test-particle simulations, we investigate the temporal dependence of the two-point velocity correlation function for charged particles scattering in a time-independent spatially fluctuating magnetic field derived from a three-dimensional isotropic ...

A Compartmented Flow Microreactor System for Automated Optimization of Bioprocesses Applying Immobilized Enzymes

Frontiers in Bioengineering and Biotechnology, 2018
In the course of their development, industrial biocatalysis processes have to be optimized in small-scale, e. g., within microfluidic bioreactors. Recently, we introduced a novel microfluidic reactor device, which can handle defined reaction compartments
