	Evaluation of negative stains for single particle analysis in electron microscopy ĎURINOVÁ, Eva Four negative stains, hafnium chloride and europium, samarium and gadolinium nitrates, were tested in single particle electron microscopy as potential alternatives to uranyl acetate, which is recently being widely restricted for its toxicity. The new stains were applied to a structurally well-described plant photosystem I, visualized by a transmission electron microscope and classified in a single particle analysis. The quality of the stains was evaluated by the obtained resolution and ability to provide reliable structural information. Detailed record
	The use of negatve staining method for viral and bacterial diagnostics using the transmission electron microscope. ŠOBEROVÁ, Tereza This bachelor thesis is focused on the negative staining method used in making diagnosis of viruses and bacteria in the transmission electrom microscope (TEM). Theoretical part provides general description of TEM, negative staining method and basic characteristics of viruses used in this project. Detailed description of procedure designed for the preparation of specimens is the key part of this project. After their display in TEM, the testis analyses the quality of virus images and comparison of effects of the most common staining agents, pH, trehalose and different times of staining on displaying the ultrastructure of biological specimens and on the size of individual viral particles. The conclusion of project contains staining agents providing the best imaging of objects that have been selected based on the evaluated results and recommendations for potential enhancement of staining properties in other agents.

	Potential uses of the low voltage transmission electron microscope LVEM 5 for the identification of viruses. BIELNIKOVÁ, Hana The aim of this study was to define and examin the capabilities of the low voltage transmission electron microscope LVEM 5 in the detection and identification of viruses, taking into consideration various contrasting agents, and a comparison to data from HV TEM.
