This is an improvement over the 8-9 % reflection observed on baseline polished glass slides. It was also able to withstand mild contact, however adhesions issues
Direct Observation of Unstained Biological Specimens in Water by the Frequency Transmission Electric-Field Method Using SEM
, 2013
"... Scanning electron microscopy (SEM) is a powerful tool for the direct visualization of biological specimens at nanometre-scale resolution. However, images of unstained specimens in water using an atmospheric holder exhibit very poor contrast and heavy radiation damage. Here, we present a new form of ..."
