This study introduces a disposable microfluidic device for rapid genetic analysis. The lab-on-a-chip system enables male-female sex determination from saliva in under 20 minutes using polymerase chain reaction (PCR).

Area of Science:

  • Biotechnology
  • Genetics
  • Microfluidics

Background:

  • Genetic analysis often requires complex laboratory equipment and lengthy procedures.
  • Point-of-care genetic testing needs rapid, user-friendly, and cost-effective solutions.

Purpose of the Study:

  • To develop a disposable microfluidic device for integrated sample preparation, polymerase chain reaction (PCR), and genetic analysis.
  • To demonstrate rapid male-female sex determination using human saliva on the developed lab-on-a-chip system.

Main Methods:

  • A continuous-flow microfluidic chip fabricated from microscope slides and double-sided tape was designed with a serpentine channel.
  • The chip incorporated 38 segments for rapid, low-volume PCR and 4 segments for DNA melting analysis, utilizing a steady-state temperature gradient.
