We need a pair of DNA/RNA analyzer-synthetizer.
What I am thinking about is a pore in a membrane, surrounded with carbon nanotubes or something similar acting as tunneling microscope probes or electrostatic field probes. Pull the DNA strand through the pore, record the signals (whether electrical, by connecting the nanotubes to something, or optical, by controlling fluorescence of the sensing molecules), reconstruct the molecule shape; voila, the sequence is out including things like base methylations.
The other part is also on a membrane; a self-assembled artificial enzyme, with four parts, fed with polynucleotide chains. Each of the four parts is sensitive to a photon of a different wavelength to absorb its energy, change conformation, and attach one nucleotide on the growing chain being printed. Then absorb another photon (that can have wavelength shared with all four elements) to restore original conformation and be prepared for next command. This way, DNA can be printed by flashes of five-colored light.
The combination of these two will allow rapid analysis and production of genetic material.
The bad news is that it allows making dangerous viruses fast.
The good news is that it also allows detecting them fast, and printing out a vaccine or inhibiting RNA or other countermeasure on demand.
Now imagine having this rig in every little provincial hospital... epidemies have no chance.
