Press release on the award of a Research Scholar Grant by the American Cancer Society

May 7, 2013

Sanjeevi Sivasankar knows a lot about how the healthy cells in your body stick together. He and his research team have studied cell adhesion proteins called cadherins. They’ve developed an instrument that takes 3-D measurements for single-molecule studies of cell adhesion. And they’ve discovered three types of bonds (ideal, catch and slip) by studying cadherins when they’re subjected to a pulling force. - Read complete press release -

Press Release describing our discovery of cadherin catch, slip and ideal bonds

November 1, 2012

The human body has more than a trillion cells, most of them connected, cell to neighboring cells. How, exactly, do those bonds work? What happens when a pulling force is applied to those bonds? How long before they break? Does a better understanding of all those bonds and their responses to force have implications for fighting disease? -Read complete press release -

Press release on our discovery with Paul Alivisatos's group that tetrapod nanocrystals have unique luminescenct properties

July 1, 2011

Observation of a scientific rule being broken can sometimes lead to new knowledge and important applications. Such would seem to be the case when scientists created artificial molecules of semiconductor nanocrystals and watched them break a fundamental principle of photoluminescence known as “Kasha’s rule.” -Read press release issued by Berkeley Labs-

Press release discussing single molecule research in the Sivasankar Lab

November 22, 2010

Sanjeevi Sivasankar was looking for a better tool to study how cells adhere to each other. Cells have surface proteins, called cadherins, that help them stick together. Different kinds of cells have different kinds of cadherins. The typical tools for observing and measuring those proteins focus on tens of thousands of them at a time - providing data on the average molecule in a sample, but not on a single molecule. -Read complete press release-

News story on winning largest grant in Grow Iowa Values Fund competition

August 19, 2010

Iowa State University researchers will use grants of state money to develop an instrument that reveals single molecules, test technology that can detect food contamination, design taller wind turbine towers and advance seven other projects with potential to grow the state's economy. - Read complete press release -
