  • Title: Easy-to-fabricate thin-film coating on PDMS substrate with super hydrophilicity and stability.
    Author: Sun L, Luo Y, Gao Z, Zhao W, Lin B.
    Journal: Electrophoresis; 2015 Mar; 36(6):889-92. PubMed ID: 25521081.
    Abstract:
    With the fast expansion of microfluidic applications, stable, and easy-to-fabricate PDMS surface coating with super hydrophilicity is highly desirable. In this study, we introduce a new kind of copolymer-based, single-layer thin-film coating for PDMS. The coating can exist in air at room temperature for at least 6 months without any noticeable deterioration in the super hydrophilicity (water contact angle ∼7°), resistance of protein adsorption, or inhibition of the EOF. In addition, this coating enables arbitrary patterning of cells on planar surfaces.
