Abstract
Methods and apparatus for sorting microstructures, such as macromolecules, viruses, cells, and minute particles, in a fluid using microlithographic sorting array that is reversibly sealed by a cover. A silicone elastomer cover is used in one embodiment. In another, silicon microstructures are used to case elastomeric replicas of obstacle arrays, the tops of which reversibly seal against a flat surface. The reversible seal allows access to fractionated microstructures within the structure for further analysis.
