We participated in research focused on the manipulation of nanoparticles in laminar flow in microfluidic chips using CNC machining (MIPEC CNC milling machine).
Excerpted from Chemical Engineering Science
The designed channel geometry was drilled into the polymethyl methacrylate (PMMA) plate using the CNC router (P2J Technology, Czech Republic). The PMMA plate with channels and the cover PMMA plate were joined using solvent-assisted bonding. Isopropyl alcohol acted as a solvent for PMMA under increased temperature and pressure (Schrott et al., 2009, Svoboda et al., 2010). Inlets and one outlet were fitted with Tygon tubing attached with ACRIFIX 192 (Evonik, Germany). ACRIFIX 192 is an ultraviolet radiation curable glue based on acrylate. The continuous (n-butanol) and dispersed (aqueous colloids) phases were dosed into the channel from glass or plastic syringes using computer-controlled high precision neMESYS pumps (CETONI, Germany).
We are grateful to the P2J Technology s.r.o. for great collaboration. We would like to thank doc. Dr. Ing. Pavlína Basařová for laboratory infrastructure and help with the interfacial tension measurement, very kind approach, and great scientific discussion.
"I would like to thank you very much for joining the project. It was a huge benefit for me personally. Sometimes things were done in a hurry and maybe not always exactly right and had to be adjusted/changed, but from my point of view it was always done perfectly. I really appreciate the excellent communication and if there is a chance for further cooperation sometime in the future, I will be very happy.
Good luck to you!"
