Microfabricated two-pin system for biomolecule crystallization

摘要

A two-pin liquid handling system for crystallizing biomolecules comprises a pair of interacting pins for holding a droplet of liquid therebetween. Each pin includes a tip spaced predetermined distance from the other pin to define a sample acquisition region. The two-pin liquid handling system includes a temperature and humidity control element for controlling the temperature of the sample acquisition region to cause transpiration of water to and from a droplet of biomolecule solution to promote crystallization of the biomolecule.
