N2 - We are developing a compact on-site water quality monitoring system to monitor components such as residual chlorine and nitrate nitrogen in environmental continuously. However precipitates of mineral and biofilm by the components of the water are formed and interfere with absorbance measurement. In previous studies, the DLC/glass can prevent mineral precipitate, but cannot prevent biofilm forming[1]. We proposed that the glass microchannel coated with diamond like carbon (DLC) and with 2-Methacryloxyethylphosphorylcholine (MPC) based copolymer on top of that[2]. (This is abbreviated MPC/DLC/glass) Mineral precipitates on the MPC/DLC/glass was less than that on the glass. In the case of Staphylococcus aureus(S. aureus), which is known to form biofilm, the adhesion on the MPC/DLC/glass was 20 % or more lower than that on the glass.
