A team of US scientists has developed the first lab on a chip device to be powered remotely.
Wen Qiao at the University of California, San Diego, made a microfluidic chip that can be powered with a commercially available radio frequency transmitter for electrophoresis experiments.
Qiao’s team made the chip by printing a circuit onto a plastic sheet. Within the circuit, they placed a chamber containing microwells.
The device is cheap to produce and simple to use and can be used in the same way as a microscope slide, with the RFID transmitter mounted next to a microscope stage and a camera to capture images of the moving nanoparticles. Qiao says that the chip will ‘greatly simplify the operation of the device for pathologists and clinicians whose training and practices have been mostly on optical microscopes, with limited experience with sophisticated electronic instruments.’
