With the majestic background music and the dark background, it is easy to remind us of the scenes in sci-fi movies such as Star Trek. In the depths of the universe, a mysterious species lays a "stone column" on the way to the planet. The ships that come and go often pass through the "stone column", and the originally mixed teams are accurately divided according to size. Three teams. Then fly to the designated channel and disappear into the universe...
In fact, the magnificent video above simulates the scene when nanoscale particles pass through a 2cm x 2cm chip. Aircraft that can control the route do not need this stupid method to determine the navigation channel. Only the particles of the human body that only make irregular movements need to be classified by such a "screen".

In the middle is the 2×2 chip (the process in the video is in this small chip, which is happening in the blue area~)
The seemingly large columns in the video that block and separate are actually only a few hundred nanometers thick, and the gap between them is very small, the smallest is only 25nm, and the maximum is only 235nm. These columns are carefully and accurately arranged by IBM scientists to achieve the goal of detecting early cancer.

The minimum gap of silicon column is 25nm
