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 …

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 …

Manipulation of single cells and particles is important to biology and nanotechnology. Our
electrokinetic (EK) tweezers manipulate objects in simple microfluidic devices using gentle …

Nanoparticles have unique properties that can be beneficial in fields ranging from quantum
information to biological sensing. To take advantage of some of some of these benefits …

Single QDs are desirable probe objects for studying near-field optical interactions with
photonic structures, however, they are often very difficult to manipulate due to their small …

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 …

We present a method to individually position single QDs with nanometer precision by
electroosmotic flow control (EOFC). Using EOFC, we demonstrate the ability to individually …

Controlled manipulation of quantum dots with nanometer precision is an essential capability
for basic science as well as for scalable engineering of nanophotonic and quantum optical …

My group's research combines advanced control theory with micro/nanoscale science. My
group was the first to demonstrate feedback control methods for microfluidic systems, and …
