    • A microelectromechanical system (MEMS) comb actuator materialized in an insulating material and a manufacturing method thereof are provided. The MEMS comb actuator includes a stationary comb fixed to a substrate; a movable comb separated from the substrate; a post fixed to the substrate; and a spring connected to the post to be separated from the substrate so as to movably support the movable comb. The stationary comb, the movable comb, the post, and the spring are formed in an insulating material layer formed on the substrate, and a metal coating layer is formed at least on the surface of the stationary comb and the movable comb. The method includes preparing a substrate; forming an insulating material layer on the substrate using silica or polymer; and selectively etching the insulating material layer and the substrate, thereby forming a stationary comb, a movable comb, a post, and a spring in the insulating material layer, and forming a metal coating layer on the surfaces of the stationary comb and the movable comb.
    • 提供了一种以绝缘材料形成的微电子机械系统(MEMS)梳状致动器及其制造方法。 MEMS梳状致动器包括固定在基底上的固定梳子; 与基板分离的可动梳子; 固定在基材上的柱; 以及连接到柱的弹簧以与基板分离以便可移动地支撑可动梳。 固定梳,可动梳,柱和弹簧形成在形成在基板上的绝缘材料层中,并且至少在固定梳和可动梳的表面上形成金属涂层。 该方法包括制备基材; 使用二氧化硅或聚合物在基板上形成绝缘材料层; 并且选择性地蚀刻绝缘材料层和基板,从而在绝缘材料层中形成静止梳子,可动梳子,柱子和弹簧,并且在固定梳子和可动梳子的表面上形成金属涂层 。

    • A biodegradable polymeric drug carrier micelle composition capable of solubilizing a hydrophobic drug in a hydrophilic environment comprises a biodegradable polymeric drug carrier micelle and a hydrophobic drug wherein the drug is physically trapped within and not covalently bonded to the polymeric drug carrier micelle. The drug carrying micelle is capable of dissolving in water to form a solution thereof, and the drug carrier comprises an amphiphilic block copolymer having a hydrophilic poly(alkylene oxide) component, and a biodegradable hydrophobic polymer component selected from the group consisting of poly(lactic acid), poly(glycoloc acid), poly(lactic-co-glycolic acid), poly(&egr;-caprolactone), a derivative thereof and a mixture thereof. Preferably the amphiphilic block copolymer has a molecular weight in a range of about 1430 to about 6000 Daltons and the hydrophilic component content is in a range of about 50 wt % to about 70 wt % based on the total weight of the block copolymer.
