Applied Physics Letters Selects ECE/Photonics Research for Cover Story
Applied Physics Letters, a weekly peer-reviewed scientific journal published by the American Institute of Physics, has selected research from the lab of ECE Assistant Professor Hatice Altug as the cover story for its January 11, 2010 issue. The research, which focused on on merging nanoplasmonics with nanofluidics, was authored by ECE Research Associate Ahmet Ali Yanik, ECE PhD students Min Huang and Alp Artar, Professor Altug, and Tsung-Yao Chang of the Massachusetts Institute of Technology.
The following is an abstract of the article, which can be found on the Applied Physics Letters website or in the January 11, 2010 print edition of the publication:
Integrated Nanoplasmonic-nanofluidic Biosensors with Targeted Delivery of Analytes
Performances of the biosensors are often limited by the depletion zones created around the sensing area which impede the effective analyte transport. To overcome this limitation, we propose and demonstrate a nanoplasmonic-nanofluidic sensor enabling targeted delivery of analytes to the sensor surface with dramatic improvements in mass transport efficiency. Our sensing platform is based on extraordinary light transmission effect in suspended plasmonic nanoholes. This scheme allows three-dimensional control of the fluidic flow by connecting separate layers of microfluidic channels through plasmonic/nanofluidic holes. To implement the proposed sensor platform, we also introduce a lift-off free nanofabrication method.
