NEC has shown us the prototype of portable DNA analyzer since 2007, but there is still a long way to go between the technology in the real world and the TV series. The system takes an hour to get results, and it's not really photogenic.
However, if you want to see the handsome machines in TV series, maybe it can be realized in 2014! NEC recently showed a prototype of a new DNA analysis chip, which can complete the DNA extraction, replication, separation and other processes in 25 minutes, which is about the same time as watching a 30 minute program (excluding advertising). Of course, in addition to the police unit will have 120000 dollars of spare money and willing to carry 32 kg of equipment around, ordinary people should not be able to afford such equipment!
