Adsorption of a Nonionic Symmetric Triblock Copolymer on Surfaces with Different Hydrophobicity
(2010)This study investigates the adsorption of a symmetric triblock nonionic polymer comprising ethylene oxide (EO) and propylene oxide (PO) blocks (Pluronic P-105, EO37PO56EO37) on a range of substrates including hydrophobic, ... -
Calcium Dependence of Fibrin Nanomechanics: The gamma 1 Calcium Mediates the Unfolding of Fibrinogen Induced by Force Applied to the "A-a" Bond
(2010)The interactions between the constituent monomers of fibrin, the polymerized protein network that provides the structural stability of blood clots, ale frequently under stress because of the dynamic nature of blood flow ... -
Distributions of Parameters and Features of Multiple Bond Ruptures in Force Spectroscopy by Atomic Force Microscopy
(2010)Force spectroscopy measurement of rupture forces of bound molecules becomes an important physicochemical tool in characterizing intermolecular interactions, Atomic force microscopy (AFM) measurements are among the most common ... -
Kinetic Parameters from Detection Probability in Single Molecule Force Spectroscopy
(2010)The detection probability of rupture events in A FM force spectroscopy measurements presents a viable alternative to standard methods for extracting kinetic parameters of dissociation. The detection probability has a maximum ... -
Quantification of the Binding Properties of Cu2+ to the Amyloid Beta Peptide: Coordination Spheres for Human and Rat Peptides and Implication on Cu2+-Induced Aggregation
(2010)There is no consensus on the coordinating ligands for Cu2+ by A beta. However, the differences in peptide sequence between human and rat have been hypothesized to alter metal ion binding in a manner that alters Cu2+-induced ... -
The Ultraviolet Absorption Coefficient of Melanosomes Decreases with Increasing Pheomelanin Content
(2010)Uveal melanosomes from the iridal stroma contain both eumelanin and pheomelanin, the ratio of which varies with iris color. Herein, we report the absorption coefficient at lambda = 244 nm for individual human iridal stroma ... -
Theoretical Framework for Nanoparticle Reactivity as a Function of Aggregation State
(2010)Theory is developed that relates the reactivity of nanoparticles to the structure of aggregates they may form in suspensions. This theory is applied to consider the case of reactive oxygen species (ROS) generation ... -
Tunable Leuko-polymersomes That Adhere Specifically to Inflammatory Markers
(2010)The polymersome, a fully synthetic cell mimetic, is a tunable platform for drug delivery vehicles to detect and treat disease (theranostics). Here, we design a leuko-polymersome, a polymersome with the adhesive properties ... -
Ultraviolet Absorption Coefficients of Melanosomes Containing Eumelanin As Related to the Relative Content of DHI and DHICA
(2010)Central to understanding the photochemical function(s) of melanosomes is the determination of their absorption properties and an understanding of how the absorption varies with the molecular composition of melanin. Herein, ...
