3-dimensional electrode patterning within a microfluidic channel using metal ion implantation

Demetri Psaltis, Herbert Shea, Samuel Rosset, Muhamed Niklaus, Jae-Woo Choi, James Adleman

The application of electrical fields within a microfluidic channel enables many forms of manipulation necessary for lab-on-a-chip devices. Patterning electrodes inside the microfluidic channel generally requires multi-step optical lithography. Here, we uti ...

Heterogenous catalysis mediated by plasmon heating

Demetri Psaltis, James Adleman

We introduce a new method for performing and miniaturizing many types of heterogeneous catalysis involving nanoparticles. The method makes use of the plasmon resonance present in nanoscale metal catalysts to provide the necessary heat of reaction when illu ...

Bacteria manipulation with optically controlled fluidic valves

Demetri Psaltis, Jae-Woo Choi, James Adleman

Optically controlled fluidic valves are utilized to concentrate and detect bacteria, selectively switch the pathway of the bacteria, and demonstrate bidirectional fluidic flow within a microfluidic channel. (C) 2009 Optical Society of America ...

Chemical separations by bubble-assisted interphase mass-transfer

Demetri Psaltis, James Adleman

We show that when a small amount of heat is added close to a liquid-vapor interface of a captive gas bubble in a microchannel, interphase mass-transfer through the bubble can occur in a controlled manner with only a slight change in the temperature of the ...

Trapping of dielectric particles with light-induced space-charge fields

Demetri Psaltis, James Adleman

Light-induced space-charge fields in lithium niobate crystals are used to trap and manipulate dielectric particles on the surface of such crystals. Without any external voltage source, strong field gradients are present in the proximity of the crystal surf ...

Optofluidic technologies

Demetri Psaltis, James Adleman

Optofluidics refers to adaptive systems that integrate optical and fluidic devices. Micro and nano-fluidics enable novel devices which introduce liquids into optical structures. We discuss recent optofluidic developments, including optically powered vapor ...
