3.-7. December 2018 Tartu (Estonia)

The Baltic colleagues Sergei Vlassov and Rynno Lohmus from Tartu (Estonia) and Boriss Polakovs from Riga (Latvia) will offer this Working group 1 training school  to interested ENBA members. Scanning Electon Microscope (SEM) is a powerfull tool for investigation of fiber materials down to few nanometer resolution (like hair, spider silk, artificial fiber produced by electrospinning, etc). In contrast to conventional SEM, one of our SEMs has special mode for observation of non-conductive speciements like e.g. biological samples without additional coating. In addition to morphology, our instruments allow to perform chemical element analysis (EDAX or Energy Dispersive X-Ray spectroscopy) in situ inside SEM. Moreover, it is possible to cut objects in situ using FIB (Focused Ion Beam) instrument to reveal inner composition and morphology.

Atomic Force Microscope is widely used in biology and related areas for imaging of fibrous proteins and DNA molecules. It is important to note, that AFM allows imaging of biomolecules in liquid. Unique application of AFM is nanomechanical imaging and nanomechanical tests. Probably, one of most striking AFM application is study of mechanical unfolding of single protein. AFM is a great tool also for for local adhesion measurements with nm resolution. With a special colloidal probes it can be readily used for biological samples. Further details about the TS and planned programme will be provided by the hosts.
