Application of KevineVoigt Model in Quantifying Whey Protein Adsorption on Polyethersulfone Using QCM-D
The study of protein adsorption on the membrane surface is of great importance to cheese-making processors that use polymeric membrane-based processes to recover whey protein from the process waste streams. Quartz crystal microbalance with dissipation (QCM-D) is a lab-scale, fast analytical technique that can precisely monitor and quantify the amount of proteins adsorbed onto the polymer surfac...
متن کاملProtein Fibrillation Studied with Qcm-d
The ability of certain polypeptides to aggregate into long, thin fibrils called amyloid structures is associated with multiple protein folding disorders and is also a major problem in biotechnological and pharmaceutical applications. Here, QCM-D has been used to monitor the changes in thickness and viscoelastic properties of multilayer amyloid deposition in situ for the first time. This provide...
متن کاملErratum to: Combined QCM-D/GE as a tool to characterize stimuli-responsive swelling of and protein adsorption on polymer brushes grafted onto 3D-nanostructures.
A combined setup of quartz crystal microbalance and generalized ellipsometry can be used to comprehensively investigate complex functional coatings comprising stimuli-responsive polymer brushes and 3D nanostructures in a dynamic, noninvasive in situ measurement. While the quartz crystal microbalance detects the overall change in areal mass, for instance, during a swelling or adsorption process,...
متن کاملQCM-D Study on Relationship of PEG Coated Stainless Steel Surfaces to Protein Resistance
Nonspecific protein adsorption generally occurs on any solid surfaces and usually has adverse consequences. Adsorption of proteins onto a solid surface is believed to be the initial and controlling step in biofouling. Surfaces modified with end-tethered poly(ethylene glycol) (PEG) have been shown to be protein-resistant to some degree. In this study, the adsorption of β-casein and lysozyme was ...
متن کاملProtein adsorption to hydrocephalus shunt catheters: CSF protein adsorption.
OBJECTIVE To assess the quantity and nature of the proteins that adsorb to hydrocephalus shunt catheters after implantation, and to determine whether sufficient could accumulate to obstruct the catheter. DESIGN Elution of proteins from 102 explanted shunt catheters, with protein assay and electrophoresis of the eluate, and scanning electron microscopy (SEM) of the catheters. RESULTS The amo...
