The Electron Microscope Unit houses seven electron microscopes. We provide advice and centralized training to both academic staff and research students in the preparation of specimens and the operation of the microscopes for the entire University. The principal users of the EMU facilities come from the faculties of engineering, medicine, and science. The unit manages three transmission electron microscopes, three scanning electron microscopes and one dual-beam focus ion beam system . Supporting this equipment is all the facilities necessary for the preparation of biological and metallic materials. These are all housed in Block T in the Queen Mary Hospital Compound.

The Electron Microscope Unit also provides facilities for a range of external organisations. If you are a researcher or student from another university or research institute and would like to use our facilities, please contact the EM unit's staff to discuss your project details.

If you wish to use our unit for contract and consulting work, please contact our EM unit's staff to discuss how we may help you.

About Us

The first electron microscope was installed in the Pathology Department of Queen Mary Hospital since 1968. In 1969, Professor James Gibson set up the Electron Microscope Unit to centralize the equipment in the University. And Now, the present Electron Microscope Unit (EMU) which houses three transmission electron microscope, three scanning electron microscopes and one dual-beam focus ion beam dedicated to providing electron microscope facilities to the whole university and to other institutions in the Hong Kong Special Administrative Region (HKSAR). The facilities are keeping up-to-date by grants from the University of Hong Kong, the Research Grants Council, the Croucher Foundation and the Jockey Club. At present, there are over 350 registered users of the EMU each year, the figure is increasing each year as the University grows in its research activities.


To maintain an up-to-date variety of electron microscopes in a centralized facility aiming at producing high-quality research and to make this as accessible as possible to our users, whether they are experienced or not.
