Did you know you can buy an Oxford Nanopore sequencer for about $2000 euro? It sits on your desk and it will sequence DNA or RNA at about 450 bases per second

It somehow grabs a free strand of DNA\RNA and pulls it through a specially constructed pore on a membrane. It reads the voltage change as it goes through because each type of base (ATGC) changes the voltage differently, and interprets the sequence and outputs the data in a file.

Doesn't even need PCR amplification because it reads a single strand.

I thought it must be fake because it sounds like something out of science fiction but Nature did an article:

Mind blowing
