Biophysics

JILA biophysicists apply tools and concepts from physics to the understanding of living systems at the molecular level, particularly in molecular biophysics, single-molecule biophysics, and biological force standards. 

The field of biophysics promises answers to important questions about the structure, dynamics, function, and interactions of biological molecules such as proteins and nucleic acids. JILA scientists are developing unique ways to precisely measure the structure and function of individual proteins and nucleic acids, both of which are important molecules for living organisms. JILA scientists are also pioneering new methods to image and measure real-time biochemical activities within living cells and tissues. These research endeavors advance our understanding fundamental biological processes and support biomedical scientists in developing new drugs and diagnostics.

Recent Highlights in Biophysics

When it comes to inspiring young people to pursue a career within the sciences, you can't start too early. At least, that's what the JILA Excellence in Diversity and Inclusivity (JEDI) group believed when they collaborated with the Colorado non-profit organization Pretty Brainy to develop a speaker series. The series, designed for girls from…

There are many ways to diagnose health conditions. One of the most common methods is blood testing. This sort of test can look for hundreds of different kinds of molecules in the body to determine if an individual has any diseases or underlying conditions. Not everyone is a fan of needles, however, which makes blood tests a big deal for some…

In a new paper, JILA physicist Thomas Perkins collaborated with CU Biochemistry Prof. Marcello Sousa to dissect the mechanisms of how certain bacteria become more virulent. The research brings together the Perkins lab expertise in single-molecule studies and the Sousa lab expertise in the type III secretion system, a key component of
