Adsorption and Migration of Poly(Vinyl Pyrrolidone) at a Fumed Silica Surface

Fabrication of curcumin-loaded mesoporous silica incorporated polyvinyl pyrrolidone nanofibers for rapid hemostasis and antibacterial treatment

Nanofiber mats have been widely applied in various biomedical fields such as drug delivery, tissue repair and wound dressing. In this study, the curcumin-loaded mesoporous silica incorporated nanofiber mats were prepared using blend electrospinning of curcumin-loaded mesoporous silica nanoparticles (CCM-MSNs) and polyvinyl pyrrolidone (PVP) for hemostasis. The prepared mats were then evaluated ...

Polyvinyl pyrrolidone (PVP) in cataract surgery.

Early reformation of the anterior chamber after intraocular surgery is of paramount importance, its absence or delay leading to peripheral anterior synechiae and aphakic glaucoma (Troncoso, 1933; Kronfeld and Grossman, 1941; McLean, I94I; Meyer and Sternberg, 1950). Selinger (1937) injected air after cataract operations to restore the normal curvature of the cornea. He concluded that air preven...

Structure of polymer solutions containing fumed silica.

Small angle neutron scattering is employed to estimate the interactions in complex multicomponent systems. The method is applied to describe a ternary system, poly(dimethyl siloxane) toluene with silica filler particles. Contrast variation by solvent deuteration is used to distinguish the three different partial structure factors of filled polymer samples, S(pp)(q), S(pf)(q), and S(ff)(q), wher...

Surface Adsorption of Polyethylene Glycol and Polyvinyl Alcohol with Variable Molecular Weights on Zinc Oxide Nanoparticles

Structural Determinants for Protein adsorption/non-adsorption to Silica Surface

The understanding of the mechanisms involved in the interaction of proteins with inorganic surfaces is of major interest in both fundamental research and applications such as nanotechnology. However, despite intense research, the mechanisms and the structural determinants of protein/surface interactions are still unclear. We developed a strategy consisting in identifying, in a mixture of hundre...
