1. An open system for performing a reaction while maintaining constant concentrations of reactants, comprising:

  • a support for performing the reaction in an open environment, wherein;

    the support is for containing or retaining biopolymers or biological particles; and

    the reaction is a submicroliter volume reaction;

    a nanoliter dispensing pipette for dispensing an amount of a liquid onto the surface of the support;

    a temperature controlling device for regulating the temperature of the support; and

    means for controlling the amount of liquid dispensed, wherein;

    the amount of liquid dispensed corresponds to the amount of liquid that evaporates from the support to thereby maintain the concentration of reactants in the reaction; and

    the system is not sealed.
