NINAAT technology

Our NINAAT (Non-Instrumented Nucleic Acid Amplification) molecular diagnostics technology can be used as a solid and reliable foundation, which can easily be adapted for military, veterinary, food, agriculture, pharmaceuticals or cosmetic needs. Everywhere, where the detection of viral, bacterial and protozoan infections or any genetic marker are required, our platform gives you the most advanced technology to do it.

Main advantages of NINAAT platform

  1. Accuracy equal to laboratory
  2. Gives multiplex results for better diagnosis
  3. Testing procedure so easy it can also be used in self tests
  4. Quickly adaptable for any new target – within months
  5. Results immediately after infection, not after immune reaction of body

How does the NINAAT technology work – the details.

Selfdiagnostics possesses unique proprietary technology for nucleic acid detection embedded into NINAAT platform enabling the application by untrained lay persons. The technology is more robust, effective and shows better sensitivity compared to lateral flow based home tests.

Technology uses crude sample; no purification is required. As a result, the platform avoids complicated and time-consuming DNA extraction procedures. The amplification process is isothermal, it does not require neither temperature cycles nor instrumentation.

The technological invention of Selfdiagnostics is combination of a robust sample preparation, specific DNA detection and isothermal amplification with simple lateral flow visualisation that are all combined with self-regulating micro-heater and operated by passive microfluidics. Thus, no specific instruments are needed, all these components are integrated and optimised into a small sized, fully disposable device.
