Even though electron microscopy could already disclose details as small as one nanometer, existing research aims to break through barriers restricting image quality and decreasing the optical dose present in the samples.
Although electron microscopy can already reveal details as small as one nanometer, ongoing research seeks to break through barriers limiting image quality and reducing the optical dose on the samples. Aberration is a common problem in electron microscopy that can reduce the resolution and quality of the images produced.
With fibers roughly the width of a human hair, researchers created a 3D imaging system that holds many potential applications, they say, ranging from remote inspection of small or dangerous machines to a miniaturized and minimally invasive endoscopic tool.
