  • Nanoporous organosilicas as pre-concentration materials for sensors
    Patent number: 7705062
    Abstract: A molecularly imprinted material made from polymerizing a monomer having the structural formula (OR)3Si—B-A-B—Si(OR)3. A is a divalent organic group, B is a saturated or unsaturated divalent hydrocarbon group or a covalent bond, and R is an independently selected saturated or unsaturated monovalent hydrocarbon group. A preconcentrator having: a container comprising in inlet and an outlet and the above material within the container. The inlet is capable of allowing a fluid to enter the container. The outlet is capable of being coupled to a sensor and of allowing the fluid to exit the container.
    Type: Grant
    Filed: January 31, 2006
    Date of Patent: April 27, 2010
    Assignee: The United States of America as represented by the Secretary of the Navy
    Inventors: Michael Markowitz, Mazyar Zeinali, Scott Trammell, Paul Charles

  • Synthesis of unagglomerated metal nano-particles at membrane interfaces
    Patent number: 6054495
    Abstract: The present invention relates to a powder of unagglomerated metallic particles. More particularly, the present invention relates to a powder of unagglomerated metallic particles having an average diameter of about 1-100 nm and the process for making the same. Additionally, the powder of unagglomerated metallic particles can be formed into a lyophilized form which upon reconstitution maintains the average diameter of between about 1-100 nm wherein the particles remain unagglomerated.
    Type: Grant

  • Polymerized phospholipid membrane mediated synthesis of metal nanoparticles
    Patent number: 5560960
    Abstract: Nanoparticle metal powder having a controllable and narrow size distribution are by electrolessly plating a metal on the interior of a vesicle made of at least one polymerized phospholipid. Electroless plating may be accomplished by catalytic reduction of the metal ion or u.v. reduction of the metal ion.
