Laser-driven PCR for ultrafast DNA detection

GNA has developed Laser PCR, for ultra-fast molecular diagnostics. This method is based on laser-heated nanoparticles. In comparison to conventional DNA amplification, we do not heat up and cool down the entire sample solution, because the nanoparticles that are added to the solution heat up immediately upon irradiation by the laser, and cool down just as quickly.
We have established an assay of three minutes for a fluoresence-free, Real-Time Laser PCR.
