My focus is on biotech :) but what about Thermofisher working on their Ion Torrent platform (although this isn't a startup). They use ISFETs for DNA sequencing.

Also there is Oxford Nanopore Technologies which sequence DNA by measuring changes in current as DNA passes through a nanopore. ONT is a startup :)
