In-line x-ray phase-contrast tomography and diffraction-contrast tomography study of the ferrite-cementite microstructure in steel

This work presents the development of a non-destructive imaging technique for the investigation of the microstructure of cementite grains embedded in a ferrite matrix of medium-carbon steel. The measurements were carried out at the material science beamline of the European Synchrotron Radiation Facility (ESRF) ID11. It was shown that in-line X...

Adaptation of nanoarrays for the study of ?-synuclein aggregation - preliminary results

In previous publications we have shown that we can perform enzymatic reactions in nanoarrays by means of a microarray-reader based on a conventional microscope. In this publication we report on a modification of this system in order to monitor the aggregation kinetics of the natively unfolded protein ?-synuclein. We describe the motivation for...

Optical detection of single molecules in nanofluidic chips

We present the latest progress on a novel technology for detecting and manipulating solution of single molecules in nanofluidic channels. This paper explains the design and fabrication of nanofluidic chip and its interface, molecule manipulation technique being used, and the optical detection method employed. Single molecule detections are...

LEDs for fluorescence microscopy

Traditional light sources for fluorescence microscopy have been mercury lamps, xenon lamps, and lasers. These sources have been essential in the development of fluorescence microscopy but each can have serious disadvantages: lack of near monochromaticity, heat generation, cost, lifetime of the light source, and possible distortions due to...
