Patent number: 8618009Abstract: Hollow conjugated polyelectrolyte (HCPE) microcapsules contain at least one conjugated polyelectrolyte and at least one other polyelectrolyte of complementary charge and the microcapsule has a hollow core. The conjugated polyelectrolyte is a polymer with a multiplicity of charged repeating units where a portion of the charged repeating units form a pi-conjugated sequence. The complementary polyelectrolyte is a polymer with a complementary charged repeating unit to the charged repeating units of the conjugated polyelectrolyte. The HCPE microcapsules can be formed by successively coating a sacrificial core with alternating layers of complementary polyelectrolytes, at least one of which is a conjugated polyelectrolyte. The sacrificial core can be removed to form the hollow center of a HCPE microcapsule.Type: GrantFiled: November 9, 2009Date of Patent: December 31, 2013Assignee: STC.UNMInventors: Kirk S. Schanze, Motokatsu Ogawa, Jonathan R. Sommer, David G. Whitten, Thomas Corbitt

Patent number: 8617464Abstract: The present invention relates to sanitization devices and methods. More particularly, the invention relates to devices and methods that significantly reduce or eliminate germs, bacteria and/or other microorganisms from objects such as bags, purses, footwear or other objects, as well as bare feet, hands, paws, hooves or other anatomical surfaces, which come into contact with them. The device and method uses germicidal radiation which exposes only the areas of the object that come into applied contact with the device. A top platform of the device is partitioned so that each partition can act independently of each other.Type: GrantFiled: January 5, 2012Date of Patent: December 31, 2013Assignee: RJG Associates, LLCInventor: James Kerr
