Portable DNA Analyzer

The world's first fully integrated portable DNA analyzer helps speed up criminal investigations and aid crime prevention efforts. Portable enough to be carried to crime scenes, it integrates all five steps of the DNA analysis process: cell collection, DNA extraction, Polymerase Chain Reaction (PCR), electrophoresis and STR analysis. The entire analysis process requires only about 25 minutes.


Conventional PCR and electrophoresis equipment is the size of a small printer and compact refrigerator, respectively. But NEC achieves amazing compactness and performance through advanced "lab-on-a-chip" technology.


DNA analysis traditionally requires an entire day to complete, which makes it difficult to create quick shortlists of suspects following crimes. But NEC's new portable DNA analyzer can quickly complete DNA analysis at the scene of the crime.


  • Cells are collected from blood samples and/or oral swab (using a cotton bud).
  • DNA is extracted from collected cells using special reagents.
  • Specific DNA fragments are multiplied through PCR (Polymerase Chain Reaction).
  • DNA fragment size is measured through electrophoresis. (Fragments travel through a charged polymer gel matrix at different rates depending on their size).
  • The person is identified via Short Tandem Repeat analysis of repeated sequences.
