In this article, we create a tuneable flow resistive pulse sensor which utilises additively manufactured parts. The sensor allows parts to be easily changed, washed and cleaned, its simplicity and versatility allows components from existing nanopore fabrication techniques using SiN, SiO2, or polyurethane membranes and glass pipettes to be integrated into a single device. This creates a multi-nanopore sensor that can simultaneously measure particles from 0.1 to 30 m in diameter. The orientation and controlled fluid flow in the device allows the sensors to be placed in series, whereby smaller 200 nm particles can be measured in the presence of 10 m particles without the risk of being blocked. Upon testing the device, SiN and SiO2 pores were found to have a low reproducibility. The most reproducible sensor material was the pulled glass pipette. Using GNM's further enhanced the ease of the device was they were robust and could be easily cleaned via sonication and reused. This allowed the same GNM to be used many times. The device here could greatly enhance the detection of microorganisms, characterise biological and inorganic nanomaterials with little or no sample preparation, and offers a platform that can be added to or run in series with other RPS fluidic chips or complimentary analytical technologies.
