Tel Aviv University President Co-authors Important Paper Unraveling the Effect of Spatial Organization on Intracellular Chemistry
Date:4/22/2010

TEL AVIV, Israel, April 22, 2010 /PRNewswire/ -- Tel Aviv University President Professor, Joseph Klafter, has co-authored a paper that brings together a myriad of seemingly unrelated chemical reactions creating a unified picture of reaction kinetics. "Geometry-Controlled Kinetics," published in Nature Chemistry on April 18, contributes to our understanding of how the geometry of a particular medium affects the motion of molecules or other particles within that medium, determining how likely they are to actually meet and react chemically with one another. Applied to living cells, this new insight may serve as fertile ground for the development of new medications. The questions addressed by the paper's authors may be likened to the following situation: Two friends have agreed to meet during the break of a football match in the stadium's coffee bar to have coffee together. How likely is this rendezvous to take place before the break is over, and what does this depend upon? Among other things, claim the researchers, the meeting depends upon some geometrical parameters, such as the size of the stadium (or cell), how crowded it is and how far apart the two friends (or molecules) are situated initially.
