Abstract

The local deposition of metal patterns on polydimethylsiloxane (PDMS)-based microfluidic devices is usually obtained with methods based on photolithography and thin-film deposition techniques. As a result, it is time consuming and expensive. We present a cleanroom-free method to generate and locally (3D) print nanoparticles inside microfluidic structures using a prototype nanoparticle printer. Films of Pt or Ag nanoparticles were printed on a PDMS microfluidic device and used for two different applications: generation of pH gradients via bipolar electrochemistry, and localized sensing of chemicals via surface-enhanced Raman spectroscopy (SERS). The results show the versatility of the approach, allowing the integration of metal nanoparticles in specific regions of microfluidic devices for various applications.
