Manipulating pH using near-infrared light assisted by upconverting nanoparticles
(Royal Society of Chemistry, 2016-10)
Near-infrared light can be used to manipulate the pH of aqueous solutions by using upconverting nanoparticle-assisted photocleavage of a ruthenium complex photobase. Upconverting nanoparticles and the photobase were also ...
Biomineralization changes with food supply confer juvenile scallops (Argopecten purpuratus) resistance to ocean acidification
Future ocean acidification (OA) will affect physiological traits of marine species, with calcifying species being particularly vulnerable. As OA entails high energy demands, particularly during the rapid juvenile growth ...
A novel pH-responsive hydrogel-based on calcium alginate engineered by the previous formation of polyelectrolyte complexes (PECs) intended to vaginal administration
(2017-10-03)
This work aimed to develop a calcium alginate hydrogel as a pH responsive delivery system for polymyxin B (PMX) sustained-release through the vaginal route. Two samples of sodium alginate from different suppliers were ...
How protonation modulates the interaction between proteins and pH-responsive hydrogel films
(Elsevier Science London, 2019-06)
Hydrogels of pH-responsive polymers are promising candidates for the design of functional biomaterials. In this context, understanding the complexity of the interaction between these materials and proteins is essential. A ...
The effect of pH on the lytic activity of a synthetic mastoparan-like peptide in anionic model membranes
(2018-11-01)
Peptide sequences containing acidic and basic residues could potentially have their net charges modulated by bulk pH with a possible influence on their lytic activity in lipid vesicles. The present study reports on a ...
Adsorption and protonation of peptides and proteins in pH responsive gels
(IOP Publishing, 2016-07)
To describe the non-trivial features of the equilibrium protonation and physical adsorption of peptides/proteins in pH-responsive hydrogels, we summarize our recent theoretical work on the subject. In these systems, molecular ...
