The Size and Morphological Study of Spherical Polyelectrolyte Complex Beads Using Environmental Scanning Electron Microscopy

Popis výsledku v původním jazyce

Development of new polyelectrolyte complex (PEC) capsules/beads for biotechnological applications such as the immunoisolation of Langerhans islets for the treatment of diabetes and the stabilization and reuse of enzymes and bacterial cells as biocatalysts is very important. Morphological characterization and study of PEC beads properties represents important challenge for electron microscopy. These very beam-sensitive bio-polymer capsules used for immobilization of cells are laboratory produced as a uniform with a controlled shape, size, membrane thickness, permeability and mechanical resistance. Owing to importance to study above mentioned parameters, samples must be inspected in their fully native and functional state. It means free of freezing, chemical contamination or preparation, shape distortion and in thermodynamically stabile and fully wet state, precisely reached after very slow changing of conditions in the specimen chamber of ESEM.
