Dust again! One of the amazingly varied forms that a single speck of dust can take - they turn from specks to angular mountains, billowing sails, or fluffy clouds. This one’s darker, smoother, and sharper than most… my guess would be that it’s maybe a microscopic shard of glass.

Nanosilverfish? Someone asked me to post a picture of what one of my nanosamples should look like - one that doesn’t have nanofluff or nanozombies or other weird etching/dust problems. The reason I haven’t posted one before is that they look kinda boring - when everything goes right, I

Nano Boba Fett? This is an artifact made of semiconductor laser material, that appeared during a process meant to etch all the laser material away. Probably it was formed by a speck of dust landing in that spot and protecting the material underneath from the etching plasma… the remnants of

A microscope image of a beat-up-looking sample that was abandoned in one of our storage boxes. It looks like maybe it used to have some kind of coating on it, which has deteriorated, or maybe the coating never came out well in the first place, which would be

Plasma in a box! We use this machine to etch silicon by blasting it with high-energy plasma, and the machine’s makers were kind enough to include a little viewport in the side so you can look in and see the plasma. It’s this pretty glowing blue-violet

This is a single speck of dust, viewed at 14,000x under an electron microscope. It’s small enough that it would fit easily inside one of your cells. My lab builds most of our nanostructures in cleanrooms, designed to keep out dust like this… compared to the size of
