The Institute for Electronics and Nanotechnology (IEN) supports the campus-wide electronics and nanotechnology community at Georgia Tech by connecting researchers across academic disciplines. As one of 10 interdisciplinary research institutes at Georgia Tech IEN facilitates interdisciplinary team forming and research, operates state-of-the-art core facilities, connects with external partners, and runs outreach and workforce development programs.
IEN catalyzes interdisciplinary collaborations and supports research and development activities in microelectronics and nanotechnology across Georgia Tech. The innovations emerging from these activities are powering solutions to societal grand challenges in providing food, water, energy, and healthcare, and in improving computing, communication, and national security.
IEN operates state-of-the-art electronics and nanotechnology core facilities at Georgia Tech, offering a broad range of fabrication and characterization capabilities for activities from basic discovery to prototype realization. Part of the NSF-funded National Nanotechnology Coordinated Infrastructure (NNCI), the core facilities are open to users from academia, industry, and government labs. The IEN core facilities enable top-down, lithography-based micro/nano-fabrication, bottom-up material synthesis, high-resolution imaging and advanced material analysis, as well as work at the intersection of life sciences and nanotechnology.
IEN offers workforce development activities for students, post-docs, and faculty as well as industrial partners. Activities range from technical seminars, workshops, and symposia to hands-on short courses. IEN also develops and delivers outreach programs for K-12 through adult learners with the aim of inspiring the next generation of scientists and engineers.
Microchip Can Electronically Detect Covid Antibodies in Just a Drop of Blood
A single drop of blood from a finger prick. A simple electronic chip. And a smartphone readout of test results that could diagnose a Covid-19 infections or others like HIV or Lyme disease.
It sounds a bit like science fiction, like the beginnings of the medical tricorder used by doctors on Star Trek. Yet researchers at Georgia Tech and Emory University have taken the first step to showing it can be done, and they’ve published their results in the journal Small.
Postdoctoral fellow Neda Rafat and Assistant Professor Aniruddh Sarkar created a small chip that harnesses the fundamental chemistry of the gold-standard lab method but uses electrical conductivity instead of optics to detect antibodies and indicate infection.
“At the heart of many diagnostics, something binds to something, and a signal is produced. That's where the optics interact and generate a light signal,” said Sarkar, a faculty member in the Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory. “What Neda has done is figured out a way of making that binding event happen between a patient sample and something from the sensor itself, so that signal will be directly electronic.”
National Nanotechnology Coordinated Infrastructure
IEN at Georgia Tech serves as a site and Coordinating Office of the NSF-funded National Nanotechnology Coordinated Infrastructure (NNCI), a network of 16 academic sites and their partners with state-of-the-art nanotechnology facilities. NNCI sites provide researchers from academia, small and large companies, and government with access to these user facilities with leading-edge fabrication and characterization tools, and technical expertise across all areas of nanoscale science, engineering, and technology.
Southeastern Nanotechnology Infrastructure Corridor
The Southeastern Nanotechnology Infrastructure Corridor (SENIC) is one of the 16 NNCI sites and a partnership between IEN and the Joint School of Nanoscience and Nanoengineering (JSNN), an academic collaboration between North Carolina A&T State University (NCA&T) and the University of North Carolina at Greensboro (UNCG).
