Area of Science:

  • Biotechnology
  • Microfluidics
  • Molecular Diagnostics

Background:

  • Global outbreaks necessitate advanced home molecular testing.
  • Current methods are hindered by complex sample prep and bulky equipment.

Purpose of the Study:

  • To develop an AI-enhanced, hand-driven microfluidic system (MACRO) for accessible home molecular diagnostics.
  • To simplify and expedite the process of infectious disease detection at home.

Main Methods:

  • Utilized a microfluidic chip with a multidimensional hourglass structure for fluid control.
  • Integrated Recombinase Polymerase Amplification (RPA) and CRISPR technologies, bypassing nucleic acid extraction.
  • Developed a mobile health platform with YoLov8 image recognition for automated result analysis.

Main Results:

  • MACRO achieved attomolar sensitivity within 60 minutes for 27 HPV subtypes with 100% specificity.
  • Clinical validation showed 98.57% accuracy and 100% specificity in 140 cervical swab samples.
  • Multiplex detection of SARS-CoV-2, Influenza A, and Influenza B in 70 samples demonstrated 100% diagnostic concordance.

Conclusions:

  • MACRO offers a cost-effective ($1.34/target) and instrument-free solution for home molecular testing.
  • The system simplifies sample preparation and detection, enhancing accessibility.
  • MACRO has significant implications for epidemic early warning and public health emergency response.
