Medical Imaging Up Close The Case for Improved Diagnostics PURDUE ELECTRICAL & COMPUTER WINTER 2006-07 HKN Marks a Milestone Inside the Centennial Celebrations OECE 2006 Seven Alumni Honored up front Vincent Walter On My Mind Serving humanity inspires the School of Electrical and Computer Engineering toward pioneering discoveries. As a collaborative team, ECE stands committed to improving people’s lives, engineering solutions to the challenges individuals and communities face. In this issue we spotlight biomedical imaging and sensing, one of several research areas within ECE focused on meeting human needs. Many of this group’s projects center on improving diagnostic capabilities and promoting patient safety—among other far-reaching goals. This work and its ensuing advances have a profound impact on the healthcare industry, and beginning on page 8 you’ll discover some of our leadership in this area. We also turn the spotlight on two esteemed faculty members who are making significant strides in health-related areas—Professor Rashid Bashir and Associate Professor Babak Ziaie. Learn more about these valued team members and their contributions to ECE’s mission by turning to page 14. It’s a privilege to share our stories with you. And as always, we encourage your feedback and value your support. Mark J. T. Smith Michael J. and Katherine R. Birck Professor and Head, School of Electrical and Computer Engineering In Your Words The following letters are in response to the article “Sharing His Passion for Engineering,” a profi le of Barrett Robinson that appeared in our last issue. Robinson is ECE’s coordinator of undergraduate labs. It was very nice to see the goings on in the department, and I particularly enjoyed the story about Barrett Robinson. He certainly is one of the “good guys” at Purdue, and he was a huge help to me during my research years and teaching years as a student in ECE. Ted Rappaport BSEE ’82, MSEE ’84, PhD ’87 I only interacted with [Barrett Robinson] once, but I will never forget it. I transferred to ECE from a community college in Florida. To complicate things further, I had also attended a technical/voca- tional school there. I was told to see if I could test out of Electrical Measurement Techniques and Electronic Device and Design Lab. Before our appointment, I was a bit nervous, for I didn’t know what kind of questions [he] would pose to me. But to my surprise, our appointment was very short and pleasant. After asking only two or three questions, [he] knew immediately that I had already mastered these subjects and gave me the credit for these two courses right away. This freed up hours for me to pursue other electives that semester.

The research also shows that the Detection? density is greater toward the free end of the cantilevers. The engineers found that the cantilevers vibrate faster after the antibody attachment if the devices have about the same nanometer-range thickness as the protein layer. Moreover, the longer the protein-coated nanocantilever, the faster the vibra- tion, which could only be explained if the density of antibod- ies were to increase with increasing lengths, Bashir says. The research group also proved this hypothesis using optical measurements and then worked with Ashraf Alam, a Birck center researcher and a professor of electrical and computer engineering, to develop a mathematical model describing the behavior. The information will be essential to properly design future “nanomechanical” sensors that use cantilevers, Bashir says. The work, funded by the National Institutes of Health, is aimed at developing advanced sensors capable of detecting minute quantities of viruses, bacteria, and other contaminants in air and fluids by coating the cantilevers with proteins, including antibodies that attract the contaminants. Such sensors will have applications in areas that include environmental-health monitoring in hospitals and homeland security. ■ Emil Venere Generated by Seyet, LLC This image depicts an array of nanocantilevers, which are Students in the News coated with antibodies to capture viruses.
