The spark within: light-emitting bioprobe fits in a single cell
If engineers at Stanford have their way, biological research may soon be transformed by a new class of light-emitting probes small enough to be injected into individual cells without harm to the host. Welcome to biophotonics, a discipline at the confluence of engineering, biology and medicine in which light-based devices – lasers and light-emitting diodes (LEDs) – are opening up new avenues in the study and influence of living cells.
The team described their probe in a paper published online February 13 by the journal Nano Letters. It is the first study to demonstrate that sophisticated engineered light resonators can be inserted inside cells without damaging the cell. Even with a resonator embedded inside, a cell is able to function, migrate and reproduce as normal.
APPLICATIONS AND IMPLICATIONS
The researchers call their device a “nanobeam,” because it resembles a steel I-beam with a series of round holes etched through the center. These beams, however, are not massive, but measure only a few microns in length and just a few hundred nanometers in width and thickness. It looks a bit like a piece from an erector set of old. The holes through the beams act like a nanoscale hall of mirrors, focusing and amplifying light at the center of the beam in what are known as photonic cavities. These are the building blocks for nanoscale lasers and LEDs.
“Devices like the photonic cavities we have built are quite possibly the most diverse and customizable ingredients in photonics,” said the paper’s senior author, Jelena Vuckovic, a professor of electrical engineering. “Applications span from fundamental physics to nanolasers and biosensors that could have profound impact on biological research.”

2013 Alfred P. Sloan Research Fellow
Stanford Electrical Engineering and Computer Science Assistant Professor Sachin Katti was recently selected as a 2013 Alfred P. Sloan Research Fellow. The Sloan Research Fellowships seek to stimulate fundamental research by early-career scientists and scholars of outstanding promise. These two-year fellowships are awarded yearly to 126 researchers in recognition of distinguished performance and a unique potential to make substantial contributions to their field.
"This is a testament to Sachin's groundbreaking work on implementing information theoretic concepts that promise significant improvements in the performance of wireless communication networks," says Stanford Electrical Engineering Professor and Chair Abbas El Gamal.

El Gamal Elected to the National Academy of Engineering
Stanford University Department of Electrical Engineering Chairperson and Hitachi America Professor Abbas El Gamal was recently elected to the National Academy of Engineering (NAE) for his contributions in information theory, information technology, and image sensors.
According to the NAE, "election to membership is one of the highest professional honors accorded an engineer." The NAE has more than 2,000 peer-elected members and foreign associates, senior professionals in business, academia, and government who are among the world’s most accomplished engineers. They provide the leadership and expertise for numerous projects focused on the relationships between engineering, technology, and the quality of life.
El Gamal's research contributions have spanned several areas, including network information theory, Field Programmable Gate Array, and digital imaging devices and systems. He has authored or coauthored over 200 papers and holds 30 patents in these areas. He is also a Fellow of the IEEE and has received several honors and awards for his research contributions, including the 2012 Claude E. Shannon Award and the 2004 INFOCOM Paper Award.
