Nanotechnology, which is developed at the impossibly small size of one billionth of a meter, is essential to everything from more powerful chips in smartphones to finding cures for the worst diseases.

When designing materials and structures at the nanoscale, it is important to be able to characterize and measure them. Getting tools to measure on these very small length scales can be challenging as ...

This fingertip-size microscope—which weighs a half-gram (0.02 oz.) and easily attaches to any smartphone camera lens with a nano suction pad—magnifies small objects up to 200 times. According to ...

Microscopy techniques have been around for many decades and are always improving. The field itself has had to improve because the samples being analyzed have been getting smaller and smaller, ...
