picometers, allowing eukaryotic cells, prokaryotic cells, viruses, ribosomes, and even single atoms to be visualized (note the logarithmic scale).<unk>  is a single-molecule<unk>  technology that uses<unk><unk><unk>  techniques. The method was conceived and developed in the 1960s and 70s, but lost favor when the extent of damage to the sample was recognized. In order for<unk>  to be clearly visualized under an<unk> <unk> , it must be labeled with heavy atoms. In addition, specialized imaging techniques and aberration corrected optics are beneficial for obtaining the resolution required to image the labeled<unk>  molecule. In theory,<unk>  could provide extremely long read lengths, but the issue of<unk>  beam damage may still remain and the technology has not yet been commercially developed.
