TL;DR: Time resolved experiments on PSII nano/microcrystals from Thermosynechococcus elongatus performed with the recently developed technique of serial femtosecond crystallography provide evidence that PSII undergoes significant conformational changes at the electron acceptor side and at the Mn4CaO5 core of the OEC.
Journal ArticleDOI
Dielectrophoretic manipulation of DNA: separation and polarizability.
TL;DR: By slowly increasing the strength of the dielectrophoretic traps in the course of the separation experiments, this new and simple technique allows for the systematic characterization of the polarizability not only for DNA but also for other biomolecules like proteins.
Journal ArticleDOI
Protein dielectrophoresis: advances, challenges, and applications.
Asuka Nakano,Alexandra Ros +1 more
TL;DR: This review summarizes the experimental studies in the field of protein DEP trapping and focusing as well as specific applications in separation, molecular patterning, on bioprobes and biosensors and the variations in experimental conditions used in the past are pointed out.
Journal ArticleDOI
Microfluidic single-cell analysis of intracellular compounds.
Tzu-Chiao Chao,Alexandra Ros +1 more
TL;DR: This review overviews the developments and achievements of microfluidic single-cell analysis of intracellular compounds in the past few years, from proof-of-principle devices to applications demonstrating a high biological relevance.
Journal ArticleDOI
Single cell manipulation, analytics, and label-free protein detection in microfluidic devices for systems nanobiology
TL;DR: In this article, a single cell analytical method for protein fingerprinting combining a structured microfluidic device with latest optical laser technology for single cell manipulation (trapping and steering), free-solution electrophoretical protein separation, and (label-free) protein detection is presented.
