History of electron microscopy at the Faculty of Medicine in Niš
Laboratory for Electron Microscopy (LEM) was formed at the end of 1969 at the Institute of pathology, Faculty of Medicine in Niš, and started to function at the beginning of 1970. Since 1990 onwards, it has been a part of the newly formed Institute for Biomedical Research (IBR) in the Faculty building.
The first transmission electron microscope (TEM T-7) was purchased in 1969, and a new one was bought in 1979 (JEOL JEM 100CX). After moving of the transmission electron microscopes, together with the equipment, to the IBR, one scanning electron microscope (SEM) was bought (JEOL JSM 5300), and equipped afterwards with an energy-dispersive spectrometer (EDS). After equipping the microscopes with accessory equipment for biologic specimen preparation (and preparation of ceramics, metals, etc.), the LEM was formed as a technical and methodological research unit of the IBR, becoming a unique research lab of this kind in the region and Serbia.
Significance and place of electron microscopy in SRCB research
Electron microscopy, as a morphological discipline, is used in the research and analysis of ultrastructural characteristics and phenomena of biological and other matter, such as metals, ceramics, polymers, biocomposites, semiconductor components.
Within SRCB, electron microscopy is functionally closely associated with other organizational units, i.e. labs and departments, such as the Lab for Experimental Pathology and Immunology, Department for Cell and Tissue Engineering, Department of Experimental Medicine, Lab for Functional Genomics and Proteomics, etc.

One of the fundamental aims of LEM has been to contribute to networking of research institutions that use EM technique in their work and to offer services to interested parties.
Possible EM users
There have not been many techniques with such a broad range of possible applications as electron microscopy. Since EM equipment is very expensive, it is not widely available to potential users. Computerization and digitalization further expands the range of EM use. Users of EM are primarily as follows: doctors, to diagnose various diseases; dentists, to examine teeth and biocompatible materials; biologists, to examine cellular and tissue ultrastructures; technologists, to examine materials used in particular processes; engineers in various fields (electronic, mechanical, civil engineering), to examine ultrastructural properties of the materials used in their professions, etc.

Methods and analyses
The following investigations can be done in the LEM:
– for diagnostic purposes: nephropathologic studies, characterization of various tumors, characterization of microorganisms;
– in dentistry: study of applied methods of preparation of dental cavities and use of biocomposite materials;
– histopathology and biology: examination of ultrastructure of different human, animal, and plant cells and tissues;
– material characteristics: studies of biomaterial (biocomposite) properties, used in regenerative medicine and tissue engineering, examination of ultrastructure of materials used in certain technologic processes, in electronics, mechanical and civil engineering, etc.
Some of the results obtained in the LEM have been published in a large number of national and international journals and reported at numerous scientific meetings.
