Scientists in Singapore have devised
magnetic micro-coils for moving beads along a microfluidic track.
Microfluidics -- the
transport of small objects or fluids around a microchip often
fabricated using the same lithographic techniques used for photonics
or electronics -- has many current and potential applications in
materials science and in bio/medical studies.
Researchers at three
Singapore organizations, the Institute of Microelectronics, the
Institute of Bioengineering and NanoTechnology, and the Nanyang
Technological University, have constructed several
different types of magnetized pillar structures which, when
energized, and move beads tens of microns around a microfluidic
