In the near future, a prostate cancer patient in Missouri may be injected with a radioisotope that can help imaging scanners accurately determine the precise location of a tumor. That diagnostic imagery could also help determine the targeting ability and exact therapeutic dose necessary to destroy the cancer cells without harming other tissues or organs in the body. A physician could then deliver to that patient a therapeutic radioisotope that is toxic to the cancer cells, without all of the physical side effects of treatments such as chemotherapy.
Professor of Radiology Jeff Smith and Chemistry Professor Silvia Jurisson chat outside the International Institute of Nano and Molecular Medicine (INMI), across the street from the MU Research Reactor (MURR). The INMI facility will provide critical infrastructure and collaborative expertise to researchers at all four University of Missouri campuses.
At the beginning of the school year, University of Missouri System President Mun Choi announced a series of investments in research and creative works that will help the system’s four universities achieve excellence through innovation. Many of those innovations will germinate and take root at the Institute of Nano and Molecular Innovations (INMI) building across the street from the MU Research Reactor (MURR) on the Mizzou campus.
COLUMBIA, Mo. – Ping! The popular 1990 film, The Hunt for Red October, helped introduce sonar technology on submarines to pop culture. Now, nearly 30 years later, a team of scientists at the University of Missouri is using this same sonar technology as inspiration to develop a rapid, inexpensive way to determine whether the drinking water is safe to consume. Based on their results, the scientists said they can determine changes in the physical properties of liquids.
This apparatus, designed by Prof. Suits and graduate student Chandika Amarasinghe and fabricated in the Department of Physics & Astronomy Machine Shop, allows his team to study collisions in molecular beams in vacuum. The beams are going almost the same direction so that the relative velocity between them can approach zero, like two cars moving the same direction on the highway. Reseachers can then take “pictures” of the scattering patterns when the collision happens. The team's current experiment uses four different powerful lasers to prepare the molecules in a single quantum state and then detect them after the collision.
The University of Missouri recently was awarded two highly coveted Multidisciplinary University Research Initiative (MURI) awards from the Department of Defense (DoD), making MU one of only three higher education institutions in the nation to receive more than one award. The University of Washington and Massachusetts Institute of Technology also received two of the 24 MURI grants awarded this year from a pool of 295 proposals.
An unexpected discovery in Professor Arthur Suits’ chemistry lab could have implications for manufacturing more efficient solar cells and improving photodynamic therapies for treating cancer, and it may contribute to research into quantum computing. At the heart of the discovery is the spin of electrons. Molecules are either nonmagnetic or magnetic depending on whether two electrons are paired with opposite spins or unpaired with same spins.
COLUMBIA, Mo. – Nanomedicine is the medical application of nanotechnology, or the use of microscopic structures to diagnose, image, treat and prevent disease. Current problems in nanomedicine include understanding and anticipating the potentially toxic impact these nanostructures have on the body and the environment once they’re released.
