Paper-Based Analytical Device for Electrochemical Flow-Injection Analysis of Glucose in Urine
(American Chemical Society (ACS), 2012)
This article describes a new design for a paper-based electrochemical system for flow-injection analysis. Capillary wicking facilitates a gravity-driven flow of buffer solution continuously through paper and nitrocellulose, ...
Effect of Surfactant Hydrophobicity on the Pathway for Unfolding of Ubiquitin
(American Chemical Society (ACS), 2012)
This paper describes the interaction between ubiquitin (UBI) and three sodium n-alkyl sulfates (SCnS) that have the same charge (Z = −1) but different hydrophobicity (n = 10, 12, or 14). Increasing the hydrophobicity of ...
Statistical Tools for Analyzing Measurements of Charge Transport
(American Chemical Society, 2012)
This paper applies statistical methods to analyze the large, noisy data sets produced in measurements of tunneling current density (J) through self-assembled monolayers (SAMs) in large-area junctions. It describes and ...
Robust Error Correction in Infofuses
(The Royal Society, 2012)
An infofuse is a combustible fuse in which information is encoded through the patterning of metallic salts, with transmission in the optical range simply associated with burning. The constraints, advantages and unique error ...
Elastomeric Origami: Programmable Paper-Elastomer Composites as Pneumatic Actuators
(Wiley-VCH Verlag Berlin, 2012)
The development of soft pneumatic actuators based on composites consisting of elastomers with embedded sheet or fiber structures (e.g., paper or fabric) that are flexible but not extensible is described. On pneumatic ...
The Magnitude of Lift Forces Acting on Drops and Bubbles in Liquids Flowing Inside Microchannels
(Royal Society of Chemistry (RSC), 2013)
Hydrodynamic lift forces offer a convenient way to manipulate particles in microfluidic applications, but there is little quantitative information on how non-inertial lift mechanisms act and compete with each other in the ...
Structural Transformation by Electrodeposition on Patterned Substrates (STEPS): A New Versatile Nanofabrication Method
(American Chemical Society (ACS), 2012)
Arrays of high-aspect-ratio (HAR) nano- and microstructures are of great interest for designing surfaces for applications in optics, bio−nano interfaces, microelectromechanical systems, and microfluidics, but the difficulty ...
Analog Modeling of Worm-Like Chain Molecules Using Macroscopic Beads-on-a-String
(Royal Society of Chemistry (RSC), 2012)
This paper describes an empirical model of polymer dynamics, based on the agitation of millimeter-sized polymeric beads. Although the interactions between the particles in the macroscopic model, and those between the ...
Miniature grating for spectrally-encoded endoscopy
(Royal Society of Chemistry (RSC), 2013)
Spectrally-encoded endoscopy (SEE) is an ultraminiature endoscopy technology that acquires high-definition images of internal organs through a sub-mm endoscopic probe. In SEE, a grating at the tip of the imaging optics ...
Paper-based electroanalytical devices for accessible diagnostic testing
(Cambridge University Press (CUP), 2013)
Microfluidic paper-based analytical devices (μPADs) use the passive capillary-driven flow of aqueous solutions through patterned paper channels to transport a sample fluid into distinct detection zones that contain the ...
