Bubbles No More: Trapping and Removal of Gas Bubbles in Single-layer Elastomeric Devices

Unwanted gas bubbles are a practical problem limiting the reliable use of microfluidic systems, particularly for the culture of biological samples. We present a robust, scalable, single-layer strategy for the elimination of gas bubbles from microchannel networks that are defined in gas-permeable substrate materials. Removal rates for nitrogen bubbles were measured in water and ethanol, and comp...

Fabrication of Elastomeric Nanofluidic Devices for Manipulation of Long DNA Molecules

We propose a method for the separation of long DNA molecules, based on elastomeric nanochannels with tunable cross section. These nanoconfinement structures can be used to stretch DNA molecules and lower their conformational entropy. The sieving mechanism of entropic recoil, proposed by Cabodi et al. [1], will be implemented using an array of elastomeric nanocheannels. Structures of various dim...

Dye Removal from Single and Quaternary Systems Using Surface Modified Nanoparticle: Isotherm and Kinetics

In this paper, dye removal ability of the surface modified nanoparticle SMN copper ferrite from single and quaternary systems was investigated. Acid Blue 92 AB92, Direct Green 6 DG6, Direct Red 23 DR23 and Direct Red 80 DR80 were used as model compounds. The effect of surfactant concentration, adsorbent dosage, dye concentration and pH on dye removal was evaluated. The adsorption isotherm and k...

Cation Dependent Surface Charge Regulation in Gated Nanofluidic Devices.

Surface charge governs nanoscale aqueous electrolyte transport, both in engineered analytical systems and in biological entities such as ion channels and ion pumps as a function of ion type and concentration. Embedded electrodes in a nanofluidic channel, isolated from the fluid in the channel by a dielectric layer, act as active, tunable gates to systematically modify local surface charge densi...
