Image resolution in
standard light microscopy is limited by the
wavelength of light and is incapable of resolving structures of
less than 200 nm. However, the resolution of electron microscopy
is limited by biological sample preparation and goes beyond 1 nm.
Transmission Electron Microscopy (TEM) is used to investigate
ultrastructure of thin samples (limited by the penetration of
electron beam): flat cells, nano-particles, biological tissues
embedded into polymers etc.
Scanning Electron Microscopy (SEM) is used to investigate fine
structure on surfaces of biological and non-biological
Research topics include detection of viruses for human patients,
inflammation, oncology, cardiovascular biology, morphology of
zebrafish retina, bacteriology, food sciences, polymer films
for biosensors, nano-particle toxicity in vitro and artificial
