Overall, our results clearly indicate that a system combining RT-LAMP and specific DNA-nanoprobes can be used as useful colorimetric method for molecular detection even with the naked eye in just 60 minutes: 30 minutes of RT-LAMP plus 30 minutes incubation with DNA-nanoprobes. These characteristics clearly suggest its usefulness as a POC diagnostic system for early, simple, cheap, fast and reliable screening of viral infections in situ.
