As a new method of malaria diagnostics, the count of Plasmodium spp. cells in red blood cells (RBCs) using hydrophilic-treated cyclic olefn copolymer (COC) plates was proposed. Oxygen plasma treatment was applied to COC plates in order to modify the surface wettability to hydrophilic using Samco RIE etcher RIE-10NR.
Polymer surface modification is an essential technique to achieve surface wettability improvement and direct substrate bonding in microfluidics fabrication. We offer plasma cleaners and UV-ozone cleaners as well as plasma etching equipment for this application. The paper below shows long-term stable hydrophilic surfaces of polymer materials (PMMA, COC, COP and PEEK) using UV-ozone treatment technologies.
