We demonstrate a new hybrid optoelectric technique that can manipulate objects across several length scales. The technique leverages a variety of different physical mechanisms to achieve the dynamic manipulation of droplets and also the in situ concentration of colloidal particles suspended in the droplets. Various physical mechanisms such as(More)
We demonstrate for the first time the dielectrophoretic trapping and manipulation of a whole animal, the nematode Caenorhabditis elegans. We studied the effect of the electric field on the nematode as a function of field intensity and frequency. We identified a range of electric field intensities and frequencies that trap worms without apparent adverse(More)
Caenorhabditis (C.) elegans is an intriguing model animal. Often times, researchers may need to silence the squirming worms and brought them to various measurements. Here we present a method to rapidly silence the tiny animal by sublethal light-induced heat in a special microfluidic chip. The worm's neural functions are temporarily shut down when a(More)
