Multiplexed C dots track cancer cells to improve patient care

By: David Nutt

For more than a decade, researchers have used glowing nanoparticles called Cornell dots, or C dots, to illuminate cancer cells, target tumors and even induce cell death . Provided This rendering shows the two C dots coded with different targeting systems, alpha-MSH, left, and cyclic RGD, which enable the particles to track different cancer markers. Now, a new iteration of C dots is expanding their impact through fluorescence-based multiplexing, a process in which multiple C dots are dispatched to track different cancer targets. C dots, which are made of silica, are able to track cancer cells... Read more

In Memorial: Stephen L Sass

Steve was born on March 11, 1940 in Bronx, NY. He received a Bachelor’s degree in Chemical Engineering from the City College of New York in 1961 and then carried out graduate studies in the Department of Materials Science at Northwestern University, earning his Ph.D. in 1966. He spent the following year as a postdoctoral researcher at Technische Hogeschool, in Delft, The Netherlands as a Fulbright Scholar. In 1967, he joined Cornell University as an Assistant Professor, advancing to full Professor in 1979. He was elevated to Emeritus status in 2008. Professor Sass was a leader in using... Read more

Nicole Chu, MSE MEng '19, creates framework for personal air quality sensors.

By: Blaine Friedlander

"Indoors or out, Nicole Chu, M.Eng. ’19, loathes breathing in carbon monoxide, sulfur dioxide and other volatile organic compounds. They’re bad for everyone’s health. Since last August, Chu has been fabricating the foundation of a wearable, personalized air quality monitoring device, by using nanotechnology, photolithography and other tools at the Cornell NanoScale Science and Technology Facility ( CNF )."

Fractured Bones, Helping Them Heal

"When Erik Taylor joined the Eve L. Donnelly lab, Materials Science and Engineering, he had lots of first-hand experience with broken bones and how they heal. He had broken nine bones. He didn’t know that he would later conduct research on bones and how to help them heal. Neither did he know this during his internship in Zurich, Switzerland, when he was mechanically testing ceramics, constructed from synthetically-produced nacre, also known as mother-of-pearl, the material found in seashells. In the course of his first-year of graduate school at Cornell University, one of his professors said,... Read more
