What are magnetic nanoparticles and how can they be used in medicine? Oregon State Associate Professor Pallavi Dhagat and graduate student Phil Lenox explain the very sensitive techniques they are developing using magnetic nanoparticles to detect a biomarker for disease in just a drop of blood or look deep inside the human body.
Biosensor technology is used to detect a wide variety of substances — from drugs, to cancer biomarkers, to chemical contaminants in our food and drinking water. Diatoms — tiny, single-celled plants found in water all over the planet — are playing a big role in a new type of biosensor being developed by Alan Wang at Oregon State. The new technology has a high selectivity and sensitivity, and is much less expensive than traditional methods of detection.
How do you prove someone tested a nuclear weapon? Researchers, Steven Czyz, Lily Ranjbar, and Salam Alhawsawi from the Radiation Detection Group at Oregon State are developing devices smaller than Pop-Tarts that use the metallic alloy CZT to detect radioactive isotopes of the noble gas xenon. This helps prove if someone tested a weapon, supporting the Comprehensive Nuclear-Test-Ban Treaty (CTBT) that's been signed by 183 nation states.
Advances in 3D graphics have made movies and video games more realistic, but can also have an impact on science. Associate Professor Eugene Zhang and Assistant Professor Yue Zhang describe their research to help medical doctors better target cancerous tumors by using 3D modeling and simulation.
