Study of Human Embryonic Stem Cells with Scanning Electron Microscope
Flodrová, Eva ; Neděla, Vilém ; Sedláčková, M. ; Hampl, A.
Potential differentiation to all the types of cells in the organism and the ability of self-renewal, makes human embryonic stem cells (hESCs) an important research subject of modern medicine. There are great expectations on them especially for their ability to cure a range of so far incurable diseases.
Image contrasts in the scanning electron microscopy
Konvalina, Ivo ; Hovorka, Miloš ; Mikmeková, Šárka ; Müllerová, Ilona
When interpreting the image contrasts we have to consider all instrument parameters that influence the transport of signal electrons to the detector. Several examples are presented.
Mapping of dopants in silicon by injection of electrons
Hovorka, Miloš ; Konvalina, Ivo ; Frank, Luděk
We have focused on planar p-type structures of various dopant densities, embedded In an n-type substrate. The samples were observed in UHV electron microscope with the cathode lens. Imaging by means of secondary electrons and its quantifiability was verified and the method was extended to very low energies.
Prospects of the scanning low energy electron microscopy in materials science
Frank, Luděk ; Mikmeková, Šárka ; Konvalina, Ivo ; Müllerová, Ilona ; Hovorka, Miloš
Employment of the scanning low energy electron microscopy (SLEEM) has been slowly making its way into the field of materials science, hampered not by limitations in the technique but rather by the relative scarcity of these instruments in research institutes and laboratories.
