This work investigates the use of nanoimprint lithography for creating nanoscale resonator devices for applications in mass sensing. A bilayer resist consisting of PMMA 495/LOR 3A allowed the ideal imprint yield for resonators with widths ranging from 300 nm down to 120 nm. Resonators with...

Micro and nanocantilever structures have been used as transducers for a plethora of sensor applications. These transducer technologies have similar shapes, but the material properties and geometrical optimizations needed to improve sensitivity are rather different. This is a record of two...

Resonant microcantilevers are promising transducers for bacteria detection because of their high sensitivities. Surface stress and mass from adsorbates affect the resonant frequency. We developed a novel method for decoupling the frequency contributions of a change in mass and surface stress on a...

Use of surfaces functionalized with phage tailspike proteins to capture and detect bacteria in biosensors and bioassays
DownloadFall 2010
The food safety and human diagnostics markets are in need of faster working, reliable, sensitive, specific, low cost bioassays and biosensors for bacterial detection. This thesis reports the use of P22 bacteriophage tailspike proteins (TSP) immobilized on silanized silicon surfaces, roughened at...

Integration of Nanomechanical Resonators in Microfluidic Systems for Specific Protein Detection
DownloadFall 2009
Nanomechanical resonators offer a pathway towards highly sensitive and label-free detection of biomolecules by transducing the mass of bound analytes into resonant frequency shifts. Zeptogram level and even single cell detections have been successfully achieved by others. However, these...
