Aufreinigung von Nano‐ und Submikronpartikeln durch präparative Gelelektrophorese.

The preparative gel electrophoresis enables the separation of nano‐ and submicron particles based on different electrophoretic mobilities. In this contribution, we show that a fractionation not only by particle size is possible, but also by surface charge/chemistry and morphology. Whilst this method, in analogy to its application in biotechnology, is yet restricted to small quantities, possibilities for an increase of the particle throughput as well as for a continuous separation are shown.
