Area of Science:

Biomedical Engineering
Molecular Diagnostics
Infectious Disease Detection

Background:

Rapid point-of-care (POC) testing is crucial for infectious disease management, especially during pandemics.
Existing methods for viral RNA detection often require specialized equipment, trained personnel, and significant time.

Purpose of the Study:

To develop a portable, low-cost electromechanical device for rapid SARS-CoV-2 viral RNA detection at the point-of-care.
To enable standalone operation without the need for professional labor or extensive equipment.

Main Methods:

Utilized the reverse-transcription loop-mediated isothermal amplification (RT-LAMP) principle for viral RNA detection.
Integrated Peltier elements for precise temperature control and a camera for automated colorimetric analysis of reaction progress.
Employed hue/saturation/value color space analysis of unfocused sample images for monitoring the RT-LAMP reaction.

Main Results:

The device achieved sensitive detection of SARS-CoV-2 viral RNA down to 10^3 copies/mL.
Detection was possible from small sample volumes (2 μL) within one hour of operation.
Automated monitoring and test termination were achieved through image analysis, simplifying the process.

Conclusions:

The developed portable device offers a rapid, accurate, and accessible solution for SARS-CoV-2 RNA detection at the point-of-care.
This technology can significantly improve the dissemination of viral testing, reducing reliance on centralized laboratories and lengthy diagnostic procedures.
