Laser surface modification of polyethersulfone films: effect of laser wavelength on biocompatibility
Biofouling is one of the most serious problems in membrane filtration systems for water treatment. An easily applicable antimicrobial finish polyethersulfone (PES) filter membranes shown by derivatizing an approved chlorin photosensitizer drug with adhesive ortho-catechol functionalities as known from l-3,4-dihydroxyphenylalanin (Dopa) residues marine mussel glues. The chemical structure second...
When blood comes in contact with dialyzer membranes, the interfacial bioactivation reactions occurring at blood/membrane boundaries affect gross mechanisms related to thrombogenicity. In presence of biocompatible polymers, adhesion and subsequent interactions platelets, as well other serum components (e.g., proteins), are altered delay thrombus formation.
Protein contaminants in carmine can cause dyspnea and anaphylactic reactions in users and consumers of products containing this pigment. The method generally used for detection of proteins in carmine has low reproducibility and is time-consuming. In this study, a rapid, simple, and highly reproducible method was developed for the detection of protein contaminants in carmine. This method incorpo...
Arsenic (V) removal using cetylpyridinium chloride (CPC) micelles and 5 kilo-Dalton (kDa) polyethersulfone (PES) membrane was studied in the presence of multiple co-ions. The concentrations of arsenic ([As]F = 0 105 μg/L) and co-ions ([CO3] = 0 – 4 mg/L, [PO4] = 0 – 0.3 mg/L, [SiO3] = 0 – 71 mg/L, and [SO4] = 0 – 400 mg/L) in simulated feed water were varied. Without the addition of CPC micelle...
