Abstract

A versatile methodology for electron microscopy (EM) grid preparation enabling total content sample analysis is presented. A microfluidic-dialysis conditioning module to desalt or mix samples with negative stain solution is used, combined with a robotic writing table to micro-pattern the EM grids. The method allows heterogeneous samples of minute volumes to be processed at physiological pH for structure and mass analysis, and allows the preparation characteristics to be finely tuned.Copyright © 2011 Elsevier Inc.
