Cells dance the waltz on top of an integrated circuit

In this movie a yeast cell (on the left) and the lung cell from a rat (on the right) are moved using a hybrid integrated circuit / microfluidic system developed in our lab.

Moving drops of fluid on the Fabutron

A hybrid integrated circuit / microfluidic chip is used to combine, independently control, and separate pL fluid drops. The droplet is water with green dye and it sits on top of the integrated circuit, sandwiched between two layers of oil. to learn more, check out our Lab on a Chip paper: http://www.rsc.org/Publishing/Journals/LC/article.asp?DOI=b710928h Duration : 0:0:16

MFDEP cell loading device proof-of-concept

Proof-of-concept of a MEMS device that I designed for my PhD dissertation, at the University of Maryland. Cells are loaded inside a micro-cell cage using dielectrophoresis. The active cancellation of the parasitic traps is necesary, thus becoming the use of multiple frequencies (MFDEP). This is the first machine of its kind, and it is very […]

Dielectrophoresis Non Contact Manipulation

Non-contact manipulation is a way to perform micro-objets positioning without adhesion perturbations. This video shows a top view of a non contact micromanipulation using negative dielectrophoresis (DEP). The microgripper’s end-effectors are in silicon with gold electrodes, and the manipulated gl balls are around 20µm diameter. An alternative tension (20V p-p) is applied between electrodes on […]

DEP Dynamic release

During micromanipulations, release is disturbed by adhesion effects and negative dielectrophoresis (DEP) can be used to actively release the object. The video presents a top view of an active release. The microgripper’s end-effectors are in silicon with gold electrodes, and the handled ball is a 20µm gl ball. An alternative tension (20V p-p) is applied […]
