Within the first few microseconds following a charged particle traversal of a cell, numerous oxygen and nitrogen radicals are formed along the track. Presented here is a method, using capillary electrophoresis, for simultaneous measurement, within an individual cell, of specific reactive oxygen species, such as the superoxide radical ([Formula: see text]) as well as the native and oxidised form...

proving to be a powerful separation technique. Electrochemical (EC) methods offer significant advantages over classical spectroscopic techniques for CE separations because electrochemistry occurs directly at an electrode surface and, thus, the limits of detection are not compromised by the small dimensions inherent in CE. This is in contrast to spectrophotometric detectors, in which the signal ...

answer. However, there is no reason why reactions cannot be carried out on such devices. Since it does not require the investment of a large chemical plant, the reactions can be performed where required, thus reducing the need to transport hazardous chemicals across countries. Since many reactors can be constructed on a single chip, and many chips located in the same area, it is evident that th...

Capillary electrophoresis is a relatively new analytical technique that has begun to have an impact in the clinical laboratory, both for routine analyses and for those that are more esoteric. Its potential for automated, rapid, high-efficiency separations makes it appealing as a replacement for some of the more labor-intensive assays carried out in electrophoretic gels and as a complement to co...

The interactions between NPs and a binary system of proteins were studied through systematic set capillary electrophoresis models. results revealed precise details the soft hard protein corona formation dynamics.
