Area of Science:

  • Biotechnology
  • Molecular Biology
  • Instrumentation Engineering

Background:

  • Real-time PCR (polymerase chain reaction) is crucial for nucleic acid quantification.
  • Existing instruments are often bulky and not suitable for field use.
  • Multiplex analysis enhances efficiency but requires sophisticated instrumentation.

Purpose of the Study:

  • To develop a compact, portable, and inexpensive real-time PCR instrument.
  • To enable rapid, multiplex analysis of nucleic acids.
  • To demonstrate the instrument's capability in biological and genetic analysis.

Main Methods:

  • Designed a portable instrument integrating a notebook computer, two reaction modules with four-color fluorescence detection, and battery power.
  • Implemented independent module control for simultaneous, varied temperature profiles and detection.
