Inhalt:
Inkjet-printing of nanoparticle inks allows the integration of electrodes directly into 2.5D structures, like microfluidic chambers. Sensing applications can additionally benefit from the nanoporous morphology of the printed electrodes. The presented results demonstrate that the high effective surface of the porous electrode is suitable for functionalization by immobilizing DNA and determining the DNA density. It is envisioned that the method facilitates the integration of porous electrodes into microfluidic systems.
