Additionally, researchers are engineering bacteria to produce outer membrane vesicles (OMVs) that carry tumor antigens. These OMVs can be produced in situ by genetically modified bacteria in the ...

Light and electron microscopy have distinct limitations. Light microscopy makes it difficult to resolve smaller and smaller features, and electron microscopy resolves small structures, but samples ...

These particles, called extracellular vesicles, are considered attractive ... electrical charges to pass through the protective outer membrane, a necessary step to keep contents and conditions ...
