Nanomechanical resonators are explored as mass sensors and molecular sensors due to their high sensitivity and real time label-free detection ability, respectively. One downside of mechanical molecular sensing is the lack of chemical information carried in the signal. For this reason, a...
We present a platform for research into nanomaterial-enhanced gas sensing using magnetomotive MEMS resonators. A microfabrication process fl ow is developed and carried out to create metallized silicon MEMS resonators. In tandem, a test system based around a balanced electronic bridge is...
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...
A capillary-type fluorescent-core microcavity refractive index sensor based on whispering gallery mode (WGM) resonances is presented. The device consists of a glass microcapillary with a thin layer of fluorescent silicon quantum dots (QDs) coated on the channel surface. The high index of the QD...
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...
