20100036084 | BIODEGRADABLE POLY(BETA-AMINO ESTERS) AND USES THEREOF - Poly(β-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. | 02-11-2010 |

20150250892 | BIODEGRADABLE POLYMERIC BUFFERS - Biodegradable pH altering polymers are disclosed. In accordance with certain aspects, the biodegradable pH altering polymers may be used to alter the pH of a microenvironment. In accordance with other aspects, the biodegradable pH altering polymers are utilized for targeted drug and gene delivery and their spontaneous release in intracellular sites of interest. | 09-10-2015 |
20150316544 | RELEASABLE MAGNETIC CELL CAPTURE SYSTEM - Compositions and methods for capturing specific cell types from a mixture in a liquid suspension of cells are provided. Targeted magnetic nanoparticles of the invention can be utilized to isolate, quantify, and characterize circulating tumor cells from complex body fluids, such as blood. The magnetic nanoparticles are releasable after targeted cells have been isolated, leaving the cells in a viable state for characterization and growth in culture. The targeted magnetic nanoparticles are fabricated using surface-functionalized super paramagnetic nanoparticles that are encapsulated in a biodegradable and biocompatible polymer to form microparticles. The microparticles are rendered target-selective by additional coatings of gelatin and gold nanoparticles which are derivatized with a targeting ligand specific for a targeted cell type. | 11-05-2015 |
