A new platform for chymotrypsin isolation from fresh bovine pancreas using an environmental friendly polyelectrolyte: Alginate
(Trade Science, 2015-09)
The separation of chymotrypsin from a crude filtrate of fresh bovinepancreas homogenate was carried out using precipitation with acommercially available negatively charged natural weak polyelectrolyte:sodium alginate. The ...
Use of Chitosan-Based Polyelectrolyte Complexes for Its Potential Application in Active Food Packaging: A Review of Recent Literature
(Multidisciplinary Digital Publishing Institute (MDPI), 2024)
Mucoadhesive Nanostructured polyelectrolyte complexes as potential carrier to improve zidovudine permeability
(2016-02-01)
Mucoadhesive drug delivery systems have been widely investigated as a strategic to allow the raising of intestinal residence time of drugs and the intimate contact with the intestinal mucosa, both factors that increase the ...
Polyelectrolytes–protein complexes: a viable platform in the downstream processes of industrial enzymes at scaling up level
(John Wiley & Sons Ltd, 2016-12)
Complexation between proteins and polyelectrolytes through electrostatic interactions gives either soluble or non-soluble complexes, leading to phase separation. The formation and the stability of these complexes are ...
New insights into physicochemical aspects involved in the formation of polyelectrolyte complexes based on chitosan and dextran sulfate
(2021-11-01)
Polyelectrolyte complexation is a technique based on interactions between polyelectrolytes of opposite charges driven by supramolecular interactions. Although many studies address the formation of polyelectrolyte complexes ...
Single method of purification for endoglucanase from Aspergillus niger by polyelectrolyte precipitation
(Elsevier, 2016-07)
The precipitation of endoglucanase from Aspergillus niger with synthetic and natural electrically charged polymers -poly vinyl sulfonate (PVS) and chitosan (CHS)- was characterized and applied to a simple method of ...
Electric Birefringence of Aqueous Solutions of a Rigid Polyelectrolyte. Polarization Mechanisms and Anomalous Birefringence Signals
(American Chemical Society, 2016-08)
We present an electric birefringence study of aqueous solutions of an intrinsically rigid polyelectrolyte, xanthan, and of mixed solutions with an oppositely charged surfactant, DTAB. The stationary electric birefringence ...
Preclinical evaluation of methotrexate-loaded polyelectrolyte complexes and thermosensitive hydrogels as treatment for rheumatoid arthritis
(2021-08-01)
This work proposes new methotrexate (MTX) loaded drug delivery systems (DDS) to treat rheumatoid arthritis via the intra-articular route: a poloxamer based thermosensitive hydrogel (MTX-HG), oligochitosan and hypromellose ...
Surfactant presence in a multilayer polyelectrolyte-enzyme system improves its catalytic response
(Elsevier Science Inc, 2009-05)
Self-assembling of poly(allylamine) containing an osmium polypyridil complex (PAOs) alternatively with sodium dodecyl sulfate (SDS) and glucose oxidase (GOx) generates a ternary multilayer system, (PAOs/SDS/PAOs/GOx)n. The ...
