Gold nanoparticle-coated capillaries for protein and peptide analysis on open-tubular capillary electrochromatography
(Wiley VCH Verlag, 2012-01)
We report a new method of immobilization of gold nanoparticles (AuNPs) on a fused-silica capillary through covalent binding. The resulting modified capillary was applied to electrophoretic systems to improve the efficiency ...
Theoretical Relation Between the Tube Zeta Potential and the Background Electrolyte Composition in Capillary Electrophoresis
This work presents a theoretical analysis of the relation between the tube zeta potential and the electrolyte solution composition typically found in capillary electrophoresis. A model including the relevant physicochemical ...
How many taxa can be recognized within the complex Tillandsia capillaris (Bromeliaceae, Tillandsioideae)? Analysis of the available classifications using a multivariate approach.
(Pensoft Publishers, 2013-03)
Tillandsia capillaris Ruiz & Pav., which belongs to the subgenus Diaphoranthema is distributed in Ecuador, Peru, Bolivia, northern and central Argentina, and Chile, and includes forms that are difficult to circumscribe, ...
Studying the interaction between peptides and polymeric nanoparticles used as pseudostationary phase in capillary electrochromatography
(Elsevier Science, 2017-01)
In this work, the interaction between synthetic bioactive peptides and polymeric nanoparticles (NPs) used as pseudostationary phase in capillary electrochromatography was studied. NPs were prepared from methacrylic acid ...
Asymmetric capillary filling of non-Newtonian power law fluids
A theoretical analysis of the capillary-driven imbibitions of non-Newtonian fluids in conical capillaries is presented. More precisely, the consequences of the variation in the fluid viscosity with the shear rate are ...
Optimization of photo-polymerized sol gel monolithic stationary phases prepared in polyacrylate-coated fused-silica capillaries for capillary electrochromatography
(Elsevier B.V., 2012-01-01)
The preparation of photo-polymerized sol-gel monolithic stationary phases (MSP) within 100 mu m internal diameter polyacrylate-coated fused-silica capillaries for use in capillary electrochromatography (CEC) was optimized. ...
A single channel capillary microviscometer
(Springer Heidelberg, 2013-10)
We have developed a microviscometer analyzing the fluid dynamics in a single channel glass microfluidic chip with a closed end. The device is able to test sample volumes of a few microliters by inserting one drop in the ...
Determination of 2-methylimidazole and 4-methylimidazole in caramel colors by capillary electrophoresis
The use of chemical preservative compounds is common in the food products industry. Caramel color is the most usual additive used in beverages, desserts, and breads worldwide. During its fabrication process, 2- and ...
Capillary Changes in Skeletal Muscle of Patients With Essential Hypertension
