1. An article for dispensing a small volume of liquid, comprising:

  • a fluid-dispensing member having two opposed surfaces in spaced relation to one another, the surfaces and space therebetween operable to generate a capillary effect;

    an actuator operable to accelerate and then abruptly decelerate the fluid-dispensing member, said abrupt deceleration causing liquid held between the two opposed surfaces to discharge therefrom; and

    a liquid director physically configured to substantially eliminate deviations in a path followed by said liquid discharged from the fluid-dispensing member.
