MSc Student

Department of Electrical and Computer Engineering, University of Alberta

Haseeb Ahmed is a final year MSc student in the Department of Electrical and Computer Engineering with a specialization in Microsystems and Nanodevices at the University of Alberta. His work in Dr. Maria Stepanova’s research group addresses the applications of ultrahigh-resolution direct-write techniques, such as electron-beam lithography (EBL), to fabricate multi-functional nanostructures with spatial resolution from 10 nm. To strengthen the links between research and teaching, Haseeb also works as a graduate teaching assistant at the Department of Electrical and Computer Engineering of the University of Alberta. Earlier, Haseeb was honored with four excellence awards during his BSc studies in Pakistan, where he volunteered as well in tutoring and mentoring, for 5 years, to help students reach their full potential in learning.

Talk Description

Fabrication and Tests of Plasmonic Nanostructures Suitable for Multifunctional Applications

Electro-optical phenomena that occur near specially engineered metal nanostructures when they are exposed to light, cumulatively termed nanoplasmonics, promise unique pathways to harvest energy of light, induce chemical changes in materials, and/or monitor these changes using a single multifunctional design. However, challenges to be overcome include superb accuracy required to fabricate proper nanostructures. We report electron beam lithography (EBL) fabrication of ultrafine plasmonic nanostructures with sub-50 nm dimensions and demonstrate their efficiency for surface-enhanced Raman scattering (SERS) detection of an important inflammatory marker, protein interleukin-6. We also discuss the potential of broader applications for the developed nanofabrication protocols.
