Control of Microfluidics
This article is on microscale flow control, on dynamically shaping flow fields in microfluidic devices to precisely manipulate cells, quantum dots (QDs), and nanowires. Compared to prior methods, manipulating microscopic and nanoscopic objects by flow control can be achieved with simpler and easy-to-fabricate devices, can steer a wider variety of objects, and enables entirely new capabilities such as placement and immobilization of ...

We show how to extend electrokinetic tweezing (which can manipulate any visible particles and has more favorable force scaling than optical actuation enabling manipulation of nanoscale objects to nanoscopic precision) from two-dimensional control to the third dimension (3D). A novel and practical multi-layer device is presented that can create both planar and vertical flow and electric field modes. Feedback control algorithms are developed... (Read More)
Electrokinetic tweezing in three dimensions is achieved for the first time using a multi-layer microfluidic device, a model-based control algorithm, and a 3D imaging algorithm connected in a feedback loop. Here we demonstrate steering of microparticles along 3D trajectories and trapping in all three dimensions with accuracy as good as 1 μm ... (Read More)
Magnetic Control for Drug Delivery
Any single permanent or electromagnet will always attract a magnetic fluid. For this reason it is difficult to precisely position and manipulate ferrofluid at a distance from magnets. We develop and experimentally demonstrate optimal (minimum electrical power) 2-dimensional manipulation of a single droplet of ferrofluid by feedback control of 4 external electromagnets. The control algorithm we have developed ... (Read More)
This article describes a range of results, from passive magnet design to optimal feedback control of a distributed ferrofluid. Representing magnetic forces as the gradient of a magnetic energy allowes design and demonstration of optimal closed-loop manipulation of a single ferrofluid droplet. The demonstrated algorithms ...

Immobilization of biological samples is often helpful in interrogating biological structure and function, particularly when studying living specimens with high-resolution optical microscopy. In such experiments, it is desirable to match the refractive index (RI) of the immobilizing substrate, especially when working with water-dipping or water-immersion optics that are designed to image into living aqueous specimens. In our survey of immobilization techniques, including microfluidics, we found that little effort is spent on RI-matching, with the result that diffraction-limited imaging is rarely (practically never) attained in these experiments. We have solved this problem using BIO-133, a commercially available, inert, and biocompatible polymer with refractive index matched to water and demonstrated that high-resolution light-sheet microscopy with water-dipping objectives is fully compatible with microfluidic setups, a goal thought by many in the field to be impossible...

Most fluorescence microscopes are inefficient, collecting only a small fraction of the emitted light at any instant. Besides wasting valuable signal, this inefficiency also reduces spatial resolution and causes imaging volumes to exhibit significant resolution anisotropy. Microscopic and computational techniques can address these problems by simultaneously capturing and subsequently fusing and deconvolving multiple specimen views ... (Read More)
Influenza viruses exhibit a complex life cycle that is still poorly understood. It involves independent replication of each of the eight segments that make up its genome and subsequent coordinated assembly as they egress from the host cell. Fast, time-resolved volumetric live cell imaging offers a powerful tool for understanding the various host mechanisms hijacked by the virus ... (Read More)
