BSA/polyelectrolyte core–shell nanoparticles for controlled release of encapsulated ibuprofen

Thermodynamic and kinetic characterization of pH-dependent interactions between bovine serum albumin and ibuprofen in 2D and 3D systems

“…6.b. As it can be seen that the release process starts slower in the case of the 3.9 w/v % sample [19] but after 500 min the dissolved amount of the IBU became equal. Various kinetic models (presented in Table 2) were applied to describe the release mechanism of the IBU from NPs.…”

“…The studied nanosized protein-non steroidal anti-inflammatory (NSAID) composites were prepared according to the procedure published previously [19,20]. Briefly, 20 w/v% BSA was dissolved in 15 ml buffer solution (McIlvaine buffer, pH 3.0).…”

Preparation and characterization of Ag–Pd bimetallic nano-catalysts in thermosensitive microgel nano-reactor

“…SAXS is especially capable of analyzing the sample in a mild condition where is almost no destruction for samples. [29][30][31][32] Moreover, SAXS could give a detailed illustration of spatial distribution of the metal nanoparticles.…”

Nanostructuring Biopolymers for Improved Food Quality and Safety

“…Whereas X-rays provided a low SLD contrast between the microemulsion and the alginate gel (thus probing the structure of the whole system), the use of neutrons enhanced the SLD contrast between the two phases, hence highlighting the structure of the microemulsion droplets embedded within the gel. In another study, fractal analysis and evaluation of the particle distance distribution function from SAXS experiments evidenced the structural changes undergone by bovine serum albumin when combined with chitosan and poly(sodium-4-styrene) sulphonate to produce core-shell nanoparticles loaded with ibuprofen for controlled release of the drug (Varga et al, 2014). Liu et al (2011) investigated the release of an enzyme encapsulated in freeze-dried chitosan/xanthan gum hydrogels and observed that the release was triggered by lowering the pH of the medium.…”
