Key result
Novel circular DNA probes detect RNA viruses including HIV-1 in clinical samples within 40 minutes.
Why the study?
Conventional antibody and RT-qPCR methods lack required sensitivity or speed for timely RNA virus detection due to reliance on substantial antigen levels or multiple thermal nucleic acid amplification steps.
A novel imaging-based method using circular DNA probes allows for accurate, sensitive, and rapid detection of RNA viruses like HIV-1 without complex thermal controls.

May enable rapid RNA virus detection; leaves open clinical validation beyond animal models and small samples.
Jang et al. (2025) studied RNA viruses / HIV-1 infection. Imaging of virus-specific DNA markers using single-stranded circular DNA probes was evaluated on Virus detection sensitivity and time. A novel imaging-based method using circular DNA probes detected RNA viruses at a genome equivalent level of 14 within 40 minutes, including effective detection of HIV-1 in clinical samples.
