Скачать или смотреть 3D printed finger pump for microfluidic and lab-on-a-chip devices

We have developed a large-volume one-stroke manual pump, as demonstrated here: https://pubs.rsc.org/en/content/artic.... Initially upcycled from an Elf-bar e-cigarette cap, we show here that we can 3D print the contraption on a Formlab, Form2D device with its Form Elastic Resin 50A.
Microfluidic-based procedures are sometimes made cumbersome and laborious by external connectors, tubing, and pumps. However, handling of finger-prick volumes of blood at the point-of-care should be easy and intuitive. A range of microfluidic devices allowing fluid pumping without the need for powered actuation or precise-pipetting, so-called ‘finger-actuated’ devices, were first introduced by Qiu et al. in 2009. This concept was further developed by a number of other groups, but most notably Juhwan Park and Je-Kyun Park demonstrated with the generation of gradients, DNA extraction, blood typing and blood-cross matching test. The devices developed by Park and Park were manufactured in PDMS with standard SU8-based soft-lithography and displaced an average of 10 μL per stroke.
Our finger-actuated pump is easier to prototype and provides larger volume capabilities. By demonstrating its fabrication on a 3D printer, we show it can be made by anyone with access to an SLA printer with elastomeric resin (approximately 50A).
