Publication number: 20120052106Abstract: A surface of an object may be treated using an antimicrobial wipe presoaked in an antimicrobial treatment solution. Alternatively, the antimicrobial treatment solution may be sprayed directly on the surface. The antimicrobial treatment solution may be made of isopropyl alcohol and an unreacted organofunctional silane antimicrobial substance that is substantially free from arsenic, silver, tin, heavy metals and polychlorinated phenols. The antimicrobial substance may include any one of: 3 trimethoxysilylpropyloctadecyldimethyl ammonium chloride; hyaluronan and its derivatives; triclosan; and a copolymer of chloropropyltrihydroxysilane and octadecylaminodimethyltrihydroxysilylpropyl ammonium chloride.Type: ApplicationFiled: July 14, 2011Publication date: March 1, 2012Inventor: Patrick E.

Patent number: RE43612Abstract: Poly(?-amino esters) prepared from the conjugate addition of bis(secondary amines) or primary amines to a bis(acrylate ester) are described. Methods of preparing these polymers from commercially available starting materials are also provided. These tertiary amine-containing polymers are preferably biodegradable and biocompatible and may be used in a variety of drug delivery systems. Given the poly(amine) nature of these polymers, they are particularly suited for the delivery of polynucleotides. Nanoparticles containing polymer/polynucleotide complexes have been prepared. The inventive polymers may also be used to encapsulate other agents to be delivered. They are particularly useful in delivering labile agents given their ability to buffer the pH of their surroundings. A system for preparing and screening polymers in parallel using semi-automated robotic fluid delivery systems is also provided.Type: GrantFiled: September 28, 2009Date of Patent: August 28, 2012Assignee: Massachusetts Institute of TechnologyInventors: Daniel Griffith Anderson, David M. Lynn, Akin Akinc, Robert S. Langer
