Abstract

Fine, high aspect ratio, and smooth surface micropillars, which never realized by conventional hot-embossing fabrication method, were fabricated on poly(methyl methacrylate) (PMMA) substrates by reactive ion etching (RIE). The separation ability of PMMA micropillars for microbeads as pseudo erythrocytes and leukocytes are comparable to Si micropillars, while the features of PMMA are superior to Si in terms of disposability, cost, and surface treatment.
