I grew up in the silicon chip Ag particles, the size of about a few hundred nanometers, I would like to ask how I do before the TEM sample?
Finish drying, look at the actual situation on the electronic microscope. If the results can not be adjusted according to the situation of sample preparation.
And then use the copper net fishing, so that particles attached to the copper network.
Alcohol is usually placed inside, with ultrasonic cleaning instrument scattered about, the purpose is to make the particles do not reunite together.
