Background:

  • Modern analytical techniques aim for lower detection limits, higher sensitivity, and faster analysis in miniaturized systems.
  • Microfluidic devices are crucial for achieving these goals, but require efficient detection systems.
  • Existing common detection methods (LIF, electrochemical, MS) have limitations for microfluidic applications.

Purpose of the Study:

  • To review recent advances in uncommon detection methods for microfluidic devices.
  • To identify universal detectors capable of real-time analysis with minimal sample manipulation.
  • To focus on esoteric detection techniques beyond the standard methods.

Main Methods:

  • Literature review of scientific publications from the last two years.
