Innovative AI-Based Rapid Testing for Viral Infections
A new AI-driven nanopore test enables quick and accurate detection of live viruses within minutes, promising to enhance viral infection diagnosis and treatment.
Researchers have developed a groundbreaking non-DNA based diagnostic test that can detect viral infections within minutes. Traditionally, confirming the presence of a virus involves DNA sequencing tests, which, although accurate, take several hours and cannot determine whether the detected virus is viable. This new method, described in a recent study published in PNAS Nexus, offers a faster alternative by analyzing virus particles as they pass through a nanopore, measuring their electrical conductivity, size, surface charge, and molecular structure.
The test utilizes an AI-powered system that interprets electrical conductivity waveforms, enabling it to identify different viruses, even distinguishing among viruses within the same family. In trials focused on herpesvirus infections that can cause ocular diseases leading to blindness, the AI nanopore system achieved a sensitivity of 100%, with specificity improving over time to more than 90% under optimized conditions.
This technology has promising implications for rapid viral diagnosis, especially in ocular conditions and potentially other infectious diseases. As it matures, it could significantly enhance clinicians' ability to quickly detect and treat viral infections, ultimately improving patient outcomes.
The study was conducted by Noriyasu Hashida and colleagues, highlighting how this innovative approach could transform infectious disease diagnostics in clinical settings.
