High-tech printing company Toppan has developed technology to manufacture glass microfluidic chips using photolithography. Mass production of microfluidic chips using the technology will make it possible to produce chips in larger volumes and at lower cost than those manufactured via current injection molding technology, which involves injecting polydimethylsiloxane (PDMS), a type of silicone resin, into a metal mold.

Microfluidic chips manufactured by injection molding using PDMS are widely used for testing due to the...Read full articleRelated content from Photonics MediaARTICLESQuantum Microscope Examines Cells in Unprecedented DetailA quantum microscope developed at the University of Queensland can resolve cellular structures that would otherwise be impossible to see.
