Optical STEM detection for scanning electron microscopy

Recent advances in electron microscopy techniques have led to a significant scale up in volumetric imaging of biological tissue. The throughput of electron microscopes, however, remains a limiting factor for the volume that can be imaged in high resolution within reasonable time. Faster detection methods will improve throughput. Here, we have...

Optimization of negative stage bias potential for faster imaging in large-scale electron microscopy

Large-scale electron microscopy (EM) allows analysis of both tissues and macromolecules in a semi-automated manner, but acquisition rate forms a bottleneck. We reasoned that a negative bias potential may be used to enhance signal collection, allowing shorter dwell times and thus increasing imaging speed. Negative bias potential has previously...

Correlating 3D light to 3D electron microscopy for systems biology

Whilst a ‘resolution revolution’ has taken place at the macromolecular scale in both electron microscopy and light microscopy, a ‘volume revolution’ has taken place at the tissue and organism level in both imaging modalities. At both ends of the scale – resolution and volume – there are concerted efforts to link the information from light and...
