ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of Invention
This invention is directed to apparatus and methods relating to programmable smart membranes and methods therefor.
2. Description of Related Art
Some related art devices include micromachined sorters. For example, U.S. Pat. No. 5,655,665, discloses a micromachined magnetic particle manipulator and separator for magnetic particles suspended in fluid.
Another micromachined sorter is disclosed in U.S. Pat. No. 5,893,974, wherein a micro scale passive filter is disclosed having sufficiently small holes to permit the passage of small desired biomolecules and at the same time prevent the passage of all larger molecules such as antibodies.
Another related art micromachined sorter includes the passive particle sorter disclosed by M. Koch, C. Schabmueller, A. G. R. Evans, A. Brunnschweiler, “A Micromachined Particle Sorter: Principle and Technology”, Tech. Digest, Eurosensors XII, Southampton, UK, Sep. 13-16, 1998.
However, these related art micromachined sorters can only sort particles by predefined features or are static/passive and thus are non-programmable.
Other related art devices include nanometer scale membranes. For example, Yoshihiro Ito, “Signal-responsive Gating by a Polyelectrolyte Pelage on a Nanoporous Membrane”, Nanotechnology, pp 205-207, Vol. 9 No. 3, September 1998, discloses a nanometer scale active membrane wherein the rate of water permeation through the membrane is controlled by pH levels and ionic strength.
Another nanometer scale membrane is disclosed in K. Eric Drexler, “Nanosystem: Molecular Machinery, Manufacturing, and Computation, John Wiley & Sons, Inc., 1992. Drexler discloses a design for a unidirectional active molecule sorter capable of transporting specific molecules across a barrier. Drexler mentions the possibility of a version of this design which can change the specificity of the transported molecules by using an elastic deformation of the receptor or altering the local charge distribution around the receptor.
Another related art nanometer scale membrane with poricity controlled by electroactive polymer actuators is described in Toribio F. Otero, Univ. del Pais Vasco, and San Sebastian, “EAP as Multifunctional and Biomimetic Materials”, in Smart Structures and Materials 1999: Electroactive Polymer Actuators and Devices, edited by Yoseph Bar-Cohen, pp.26-34, 1999.
However, all of the related art nanometer scale membranes have filtering functions that are preset and which cannot be subsequently altered.
Related art control methods and techniques include the system disclosed in U.S. Pat. No. 6,011,372, which is a unified modular system of drives and controls for mobile robotic applications. However, the robot of this modular system is not modular and the control of the robot is hierarchical.
