Název v původním jazyce
Structure investigation of hydrogels using a cryo-SEM
Popis výsledku v původním jazyce
The aim of this study is to examine and describe the ultrastructure of a selected hydrogel, namely hyaluronic acid and agarose. Several types of low temperature sample preparation protocols were compared. Especially, the effect of various freeze-etching times was investigated. In addition, besides the ultrastructural characterization by cryo-SEM the chemical analysis of selected samples was performed by Raman spectroscopy (RS). RS is an optical method enabling chemical analysis of a microscopic sample by laser beam. Fast and reliable monitoring and identification of chemical additives specific for selected hydrogels is performed by a library of spectra in the so-called fingerprint area. Experimental results can contribute to the widening of knowledge about the influence of hydrogel composition on its structure. The comparison of selected techniques can be recognized as suitable for the structural and chemical analysis applicable to other hydrogel systems as well.
