Fifth Summer Seminar Held

Event Date: July 19, 2005
The creation of gaps in nanoscale wires is of interest for both fundamental and applied research. Fundamental research benefits from a better understanding of how to form such gaps as well as the study of them. Filling the gaps with other materials helps advances research on the next generation of electronic devices. In addition, the wires created can be selectively placed across the gaps of microfabricated electrodes, allowing the electrical properties of the nanowire(s) to be determined.

In the fifth summer seminar series, graduate student Joseph Kinsella presented his research on using DNA as a template for the assembly of magnetic nanoparticles that can then be stretched to form nanowires. Working under Professor Albena Ivanisevic, Kinsella demonstrated that this process can be used to form the wires, and that the use of selected enzymes to target pre-determined sections of the DNA strand to create the gaps. While burning gaps (electrical formation) and pulling (stress/mechanical formation) are used to create gaps, using nanoparticle-coated DNA allows for more precise placement and replication. Future research includes working to form wires with different particle components by recombining the fragmented wires using methods similar to those used in recombinant DNA technologies.

Open to students, faculty, staff, and prospective students, the Summer Seminar series provides students the opportunity to present research and develop presentation skills in a friendly and supportive environment. After the presentation, there is a session for technical questions, then a session to provide feedback and constructive criticism on the presentation itself.

Students who take part in the series are eligible for the Fearnot Prize. Dr. Neal Fearnot, a Purdue alumnus and president of MED Institute, established this award because he felt that the experience he gained as a student presenter at the BME summer seminar series was extremely valuable. The award is presented to the graduate student whose presentation receives the highest evaluation from the faculty, students and staff attending the seminars.
