Journal ArticleDOI
Weighing of biomolecules, single cells and single nanoparticles in fluid
Thomas P. Burg,Michel Godin,Scott M. Knudsen,Wenjiang Shen,Greg Carlson,John S. Foster,Ken Babcock,Scott R. Manalis +7 more
TL;DR: It is demonstrated that suspended microchannel resonators can weigh single nanoparticles, single bacterial cells and sub-monolayers of adsorbed proteins in water with sub-femtogram resolution (1 Hz bandwidth) and the observation that viscous loss due to the fluid is negligible compared to the intrinsic damping of the silicon crystal resonator.
Journal ArticleDOI
Measuring the mass, density, and size of particles and cells using a suspended microchannel resonator
TL;DR: In this paper, the mass, density and size of cells and nanoparticles were measured using suspended microchannel resonators, where the masses of individual particles were quantified as transient frequency shifts, while the particles transit a microfluidic channel embedded in the resonating cantilever.
Journal ArticleDOI
Suspended microchannel resonators with piezoresistive sensors
Jungchul Lee,Jungchul Lee,Rumi Chunara,Wenjiang Shen,Kristofor R. Payer,Ken Babcock,Thomas P. Burg,Scott R. Manalis +7 more
TL;DR: The first electronic detection of SMR resonance frequency is demonstrated by fabricating piezoresistive sensors using ion implantation into single crystal silicon resonators to enable new uses for the SMR in both multiplexed and field deployable applications.
Journal ArticleDOI
Magnetic Force Microscopy: Recent Advances and Applications
TL;DR: In this paper, the principles of magnetic force microscopy and recent advances in imaging methods and probes are reviewed. Some current applications of MFM in experimental micromagnetism and materials development are also discussed, as well as challenges in image interpretation and in using MFM for quantitative work.
Patent
Method and apparatus for high throughput diagnosis of diseased cells with microchannel devices
TL;DR: In this article, a method and apparatus comprising a microfluidic channel with a constriction, for trapping infected red blood cells while allowing healthy red cells to deform and pass through the channel.
