Rapid generation of spatially and temporally controllable long-range concentration gradients in a microfluidic device.
The ability to rapidly generate concentration gradients of diffusible molecules has important applications in many chemical and biological studies. Here we established spatially and temporally controllable concentration gradients of molecules (i.e. proteins or toxins) in a portable microfluidic device in an easy and rapid manner. The formation of the concentration gradients was initiated by a p...
متن کاملTemporal Variation Pattern of Runoff Generation and Rill Erosion in Different Soils and Slope Gradients
This study was conducted to investigate the temporal variations of runoff and rill erosion in various soil textures under different slope gradients. So, a laboratory experiment was set up in three soil textures (loam, clay loam, and sandy clay loam) and four slope gradients (5, 10, 15, and 20%) using the completely randomized design with three replications. Runoff production and rill erosion we...
متن کاملFreeze-cutting of density gradients.
There are numerous techniques for sampling density gradients in experiments involving the preparative ultracentrifuge. Among the sampling procedures used are: drawing liquid samples from the top of the density gradient with modified pipettes (J. B. Sinclair et al., Phytopathology 47:372, 1957), displacement through the top of the density gradient (E. Huff, H. Oxley, and C. S. Silverman, J. Bact...
متن کاملCombining Step Gradients and Linear Gradients in Density.
Combining aqueous multiphase systems (AMPS) and magnetic levitation (MagLev) provides a method to produce hybrid gradients in apparent density. AMPS—solutions of different polymers, salts, or surfactants that spontaneously separate into immiscible but predominantly aqueous phases—offer thermodynamically stable steps in density that can be tuned by the concentration of solutes. MagLev—the levita...
متن کاملDensity gradients at hydrogel interfaces for enhanced cell penetration.
We report that stiffness gradients facilitate infiltration of cells through otherwise cell-impermeable hydrogel interfaces. By enabling the separation of hydrogel manufacturing and cell seeding, and by improving cell colonization of additively manufactured hydrogel elements, interfacial density gradients present a promising strategy to progress in the creation of 3D tissue models.
