In recent years, several new methods have been developed to precisely manipulate small
particles using optical, electric, acoustic, magnetic, or fluidic fields. Automated fluidic …

Isolated microfluidic stagnation point flows–stagnation point flows formed within microfluidic
interfaces–have come a long way as a tool for characterizing materials …

Optical tweezers are a highly versatile tool for exploration of the mesoscopic world,
permitting non-contact manipulation of nanoscale objects. However, direct illumination with …

We report an integrated microfluidic device for fine-scale manipulation and confinement of
micro-and nanoscale particles in free-solution. Using this device, single particles are …

Iron oxide cores of 35 nm are coated with gold nanoparticles so that individual particle
motion can be tracked in real time through the plasmonic response using dark field optical …

High precision control of micro-and nanoscale objects in aqueous media is an essential
technology for nanoscience and engineering. Existing methods for particle trapping primarily …

Trapping and manipulation of microscale and nanoscale particles is demonstrated using the
sole action of hydrodynamic forces. We developed an automated particle trap based on a …

Perfectly ordered states are targets in diverse molecular to microscale systems involving, for
example, atomic clusters, protein folding, protein crystallization, nanoparticle superlattices …

We report simulated and experimental image quality for contact imaging, a method for
imaging objects close to the sensor surface without intervening optics. This technique …

We demonstrate a single molecule trapping concept that modulates the actual driving force
of Brownian motion the temperature. By spatially and temporally varying the temperature at …
