Microbiotas of the Late Precambrian Hunnberg Formation, Nordaustlandet, Svalbard
(The Paleontological Society, 1984)A distinctive carbonate shallowing-upward sequence occurs within the Upper Riphean (750-800 Ma) Hunnberg Formation of Nordaustlandet, Svalbard. Clastic limestones deposited in an open coastal marine environment pass upward ... -
Microbristle in gels: Toward all-polymer reconfigurable hybrid surfaces
(Royal Society of Chemistry (RSC), 2010)We report on the fabrication of biologically-inspired ‘‘smart’’ surfaces using hybrid architectures comprising polymer microbristle embedded in a hydrogel layer. The dynamic bending of the microposts—the passive structural ... -
Microbubbles Reveal Chiral Fluid Flows in Bacterial Swarms
(National Academy of Sciences, 2010)Flagellated bacteria can swim within a thin film of fluid that coats a solid surface, such as agar; this is a means for colony expansion known as swarming. We found that micron-sized bubbles make excellent tracers for the ... -
Microcantilever Q Control Via Capacitive Coupling
(American Institute of Physics, 2012)We introduce a versatile method to control the quality factor Q of a conducting cantilever in an atomic force microscope (AFM) via capacitive coupling to the local environment. Using this method, Q may be reversibly tuned ... -
Microclimactic Effects of the Loss of a Foundation Species from New England Forests
(Ecological Society of America, 2012)Foundation species have a major impact on biotic and abiotic processes and create a stable environment for many other species. Eastern hemlock (Tsuga canadensis), a foundation tree species native to North America, is ... -
Microfabrication and Device Parameter Testing of the Focal Plane Arrays for the Spider and BICEP2?Keck CMB Polarimeters
(2009)Spider and BICEP2/Keck are projects to study the polarization of the cosmic microwave background (CMB). The focal planes for both require large format arrays of superconducting transition edge sensors (TES's). A major ... -
A Microfluidic Device for Whole-Animal Drug Screening Using Electrophysiological Measures in the Nematode C. Elegans
(Royal Society of Chemistry (RSC), 2012)This paper describes the fabrication and use of a microfluidic device for performing whole-animal chemical screens using non-invasive electrophysiological readouts of neuromuscular function in the nematode worm, C. elegans. ... -
A microfluidic device to investigate axon targeting by limited numbers of purified cortical projection neuron subtypes
(Royal Society of Chemistry (RSC), 2012)While much is known about general controls over axon guidance of broad classes of projection neurons (those with long-distance axonal connections), molecular controls over specific axon targeting by distinct neuron subtypes ... -
Microfluidic fabrication of water-in-water (w/w) jets and emulsions
(AIP Publishing, 2012)We demonstrate the generation of water-in-water ( w/w) jets and emulsions by combining droplet microfluidics and aqueous two-phase systems ( ATPS). The application of ATPS in microfluidics has been hampered by the low ... -
Microfluidic heart on a chip for higher throughput pharmacological studies
(Royal Society of Chemistry (RSC), 2013)We present the design of a higher throughput “heart on a chip” which utilizes a semi-automated fabrication technique to process sub millimeter sized thin film cantilevers of soft elastomers. Anisotropic cardiac microtissues ... -
Microfluidic Methods for High-Throughput Biological Screening
(2015-09-23)Often in biology, rare individuals within a population dominate the population’s overall behavior, and we wish to extract those individuals for further analysis. We design a sorting instrument as a flexible platform for ... -
A Microfluidic Microprocessor: Controlling Biomemetic Containers and Cells using Hybrid Integrated Circuit / Microfluidic Chips
(Royal Society of Chemistry, 2010-06-02)We present an integrated platform for performing biological and chemical experiments on a chip based on CMOS (complementary metal–oxide–semiconductor) technology. We have developed a hybrid integrated circuit (IC) / ... -
Microfluidic Platform for the Detection of Single Cell Immune Activity and Tag-Free Selection of Individual Target-Cell Responsive Effector Cells
(2016-05-19)Adoptive Immunotherapy has long been explored as a possible cure for challenging diseases including cancer and HIV infection. The key step in such therapies is to identify and select disease-specific effector cells, which ... -

Microfluidic Production and Characterization of Lipid Vesicles, Polymer Vesicles, and Hybrid Polymer/Lipid Vesicles
(2022-06-06)Lipid vesicles are aqueous volumes surrounded by a bilayer of lipid molecules, which are amphiphilic molecules with their head groups facing water and tail groups facing oil. These vesicles are simple models for cell ... -
Microfluidic sorting with high-speed single-layer membrane valves
(AIP Publishing, 2010)Sorting is one of the most important applications of microfluidic devices; however, current sorters place specific requirements on the density, size, and electrical properties of the objects to be sorted, limiting ... -
Microfluidic Transistors for the Control of Liquids and Particles
(2023-11-21)Microfluidics has played a significant role in the development of high-throughput and quantitative technologies for biology, medicine, genomics, and chemistry. Rapid growth in these fields have prompted a rising need in ... -
