Researchers demonstrate a novel method for trapping carbon monoxide molecules using electric field traps on a chip. This breakthrough enables a gas-phase molecular laboratory on a chip for various polar molecules.

Area of Science:

  • Physics
  • Chemistry
  • Nanotechnology

Background:

  • Trapping atoms on chips is established, but molecular trapping remains difficult.
  • Developing chip-based molecular manipulation is crucial for advanced research.

Purpose of the Study:

  • To demonstrate a new method for trapping and manipulating molecules on a chip.
  • To enable the creation of a "molecular laboratory on a chip" for diverse polar molecules.

Main Methods:

  • Direct loading of carbon monoxide molecules from a supersonic beam onto a chip.
  • Confining molecules in tubular electric field traps (20 µm diameter) moving with the beam.
  • Bringing an array of miniaturized moving traps to a standstill on the chip.

Main Results:
