The Chemistry Department invites you to attend a seminar Thursday, October 9, 11 a.m. in the New Science Building, Room 200. The guest speaker is Dr. Novella Bridges of the Pacific Northwest National Laboratory.

Abstract

“Radiogels: Reversible Gels for Delivery of Medical Radioisotopes: Using our RadioGelâ„¢ technology, it will be possible to successfully deliver a self-contained high-dose of radiation into a cancerous tumor. This technology will enable the maximum dose of radiation to be absorbed and allow a concise and uniform delivery into the targeted cancer tissue. This delivery system will minimize the radiation dose to the patient and other closely associated healthy tissue that might garner side effects.

“A vital component of the radiogel is a new polymer-based material. This material is biodegradable, water-based and thermally reversible stimulus-sensitive gelling copolymer. This copolymer is combined (in solution) with a high-energy, beta-particle-emitting radioisotope (Yttrium-90) in the form of a colloid. It is the colloid that is trapped within the solidified matrix of the gel that produces the high-dose of radiation.
