Dependence of Avidity on Linker Length for a Bivalent Ligand–Bivalent Receptor Model System
(American Chemical Society, 2012)
This paper describes a synthetic dimer of carbonic anhydrase, and a series of bivalent sulfonamide ligands with different lengths (25 to 69 Å between the ends of the fully extended ligands), as a model system to use in ...
Camouflage and Display for Soft Machines
(American Association for the Advancement of Science (AAAS), 2012)
Synthetic systems cannot easily mimic the color-changing abilities of animals such as cephalopods. Soft machines—machines fabricated from soft polymers and flexible reinforcing sheets—are rapidly increasing in functionality. ...
Measuring Markers of Liver Function Using a Micropatterned Paper Device Designed for Blood from a Fingerstick
(American Chemical Society, 2012)
This paper describes a paper-based microfluidic device that measures two enzymatic markers of liver function (alkaline phosphatase, ALP, and aspartate aminotransferase, AST) and total serum protein. A device consists of ...
Comparison of SAM-Based Junctions with Ga2O3/EGaIn Top Electrodes to Other Large-Area Tunneling Junctions
(American Chemical Society, 2012)
This paper compares the J(V) characteristics obtained for self-assembled monolayer (SAM)-based tunneling junctions with top electrodes of the liquid eutectic of gallium and indium (EGaIn) fabricated using two different ...
Magnetic Levitation as a Platform for Competitive Protein–Ligand Binding Assays
(American Chemical Society, 2012)
This paper describes a method based on magnetic levitation (MagLev) that is capable of indirectly measuring the binding of unlabeled ligands to unlabeled protein. We demonstrate this method by measuring the affinity of ...
Paper-Based, Capacitive Touch Pads
(Wiley-VCH Verlag Berlin, 2012)
Metallized paper is patterned to create touch pads of arrayed buttons that are sensitive to contact with both bare and gloved fingers. The paper-based keypad detects the change in capacitance associated with the touch of ...
Analyzing Forensic Evidence Based on Density with Magnetic Levitation
(Wiley-Blackwell, 2013)
This paper describes a method for determining the density of contact trace objects with magnetic levitation (MagLev). MagLev measurements accurately determine the density (±0.0002 g/cm3) of a diamagnetic object and are ...
The Rate of Charge Tunneling through Self-Assembled Monolayers Is Insensitive to Many Functional Group Substitutions
(Wiley-VCH Verlag Berlin, 2012)
Insensitivity: A series of molecules containing a common head group and body as well as structurally varied tail groups (-R) has been used in junctions with the structure Ag/S(CH2)4CONH(CH2)2R//Ga2O3/EGaIn to study the ...
A Simple Two-Dimensional Model System to Study Electrostatic-Self-Assembly
(Royal Society of Chemistry (RSC), 2012)
This paper surveys the variables controlling the lattice structure and charge in macroscopic Coulombic crystals made from electrically charged, millimeter-sized polymer objects (spheres, cubes, and cylinders). Mechanical ...
The Electrical Resistance of AgTS-S(CH2)n-1CH3//Ga2O3/EGaIn Tunneling Junctions
(American Chemical Society (ACS), 2012)
Tunneling junctions having the structure AgTS–S(CH2)n−1CH3//Ga2O3/EGaIn allow physical–organic studies of charge transport across self-assembled monolayers (SAMs). In ambient conditions, the surface of the liquid metal ...
