Thermosensitive-polymer-coated magnetic nanoparticles: adsorption and desorption of bovine serum albumin.
Adsorption and desorption behavior of Bovine Serum Albumin (BSA) on surface-modified magnetic nanoparticles covered with thermosensitive polymer (PNIPAM) was investigated as a function of temperature, pH, and ionic strength. Functionalization of surface-modified magnetic particles was performed by seed polymerization using N-isopropylacrylamide (PNIPAM) as the main monomer. Characterization of ...

for the equilibrium properties is obtained. The coverage near saturation depends logarithmically on the ratio between the adsorption rate, k+, and the desorption rate, k−, ρeq ∼= 1− 1/ log(k+/k−), when k+/k− 1. A time dependent version of the reversible problem with immediate adsorption (k+ = ∞) is also considered. Both heuristic arguments and numerical simulations reveal a logarithmically slow...
متن کاملAdsorption and desorption of lysozyme on thermosensitive nano-sized magnetic particles and its conformational changes
Introduction In recent years, there has been a great interest in the fabrication of stimuli responsive polymer microspheres for technological application and fundamental studies. These stimuli responsive smart and intelligent polymeric materials can respond in shape or volume changes to small external stimuli such as temperature, pH and ionic strength etc [1, 2]. Among these stimuli responsive ...
متن کاملSteady-state and dynamic desorption of organic vapor from activated carbon with electrothermal swing adsorption.
A new method to achieve steady-state and dynamic-tracking desorption of organic compounds from activated carbon was developed and tested with a bench-scale system. Activated carbon fiber cloth (ACFC) was used to adsorb methyl ethyl ketone (MEK) from air streams. Direct electrothermal heating was then used to desorb the vapor to generate select vapor concentrations at 500 ppmv and 5000 ppmv in a...
متن کاملAdsorption and desorption properties of trans-resveratrol on cellulose cotton.
The adsorption and desorption properties of trans-Resveratrol (Res) on the cellulose cotton were investigated under various conditions, such as the pH, alcohol percentage, temperature and equilibrium times. Moreover, the acidic-dissociation constants were determined to be pKa1 = 8.01, pKa2 = 9.86 and pKa3 = 10.5 by a curve-fitting method. Also, it was found that the adsorption depended on the t...
