Phenom Pharos G2 Desktop FEG-STEM for in-house biological and materials science sample analysis

While scanning electron microscopes (SEMs) offer high resolution topography imaging of bulk samples, integrating scanning transmission electron microscopy (STEM) capabilities into SEMs is helping to reveal a wealth of information for structure analysis of electron-transparent specimens. Traditionally STEM systems have been available as an additional modality for complex TEM systems, promising increased contrast, particularly from unstained tissue sections, but they have not been widely available outside of specialist comprehensive microscopy centres.

The highly automated Desktop Thermo Scientific™ Phenom Pharos™ G2 FEG-SEM with the new scanning transmission electron microscopy (STEM) detector delivers high contrast under low voltage, increasing visibility of structures and morphology to achieve a higher resolution close to a TEM with a larger field of view.

The STEM Sample Holder for the Phenom Pharos Desktop SEM is the world’s first desktop scanning transmission electron microscope sample holder combined with a field emission gun (FEG) source for in-house biological and materials science sample analysis. With its dedicated detector, the holder offers bright field, dark field, and high-angle annular dark field imaging at resolutions less than 1nm. Seamlessly integrated within the user-friendly Phenom SEM interface, these enhanced capabilities empower both novice and experienced users to obtain exceptional data in as little as one minute from sample loading.

Electron microscopy plays a major role in diagnosing renal and rare diseases, however high costs can limit its access. Professor Murray Killingsworth from NSW Health Pathology’s Liverpool lab and Dr Tzipi Cohen Hyams from the Correlative Microscopy Facility at the Ingham Institute for Applied Medical Research are working with ATA Scientific and Thermo Fisher Scientific International to develop the Phenom Pharos FEG-SEM with low kV STEM imaging and assess how it may be used for high resolution ultrastructural characterisation of soft tissue and cells for cell biology and pathology. The team recently won the “Recognising our Pioneering Spirit” Award for their pioneering work at the 2023 NSW Health Pathology Awards! The group will also be presenting their latest findings and demonstrating the Phenom Pharos together with ATA Scientific during the UltraPath XXI conference 2024 to be held in Sydney (September 30th – October 4, 2024).
