Limited aqueous solubility, stability, and bioavailability are common characteristics of hydrophobic drugs which impedes the delivery of drugs to intended site of action. In recent years, polymeric nanoparticles as drug delivery vehicle are widely used in various chronic disease therapies owing to their favorable features such as versatility, biocompatibility, biodegradability, and biomimetic c...

Using 12CO and 13CO liganded protein and 406 nm laser excitation, multiple stretching (upsilon(Fe-CO), upsilon(C-O)) and bending (delta(Fe-C-O)) modes have been identified in the resonance Raman spectra of monomeric and polymeric Glycera hemoglobins. While the monomer fraction Glycera dibranchiata hemoglobin has upsilon(Fe-CO) = 496 cm-1, two distinct upsilon(Fe-CO) modes are found at 498 cm-1 ...

Polymeric hindered amine light stabilizers (polymeric HALS) have been extensively studied because they combine a high ability to protect the polymers against harmful effects of weathering with minimum physical loss. In this study a new polymeric N-methylated HALS was synthesized by the radical copolymerization of a cyclic tertiary amine with vinyl acetate (VAc). 4-Acryloyloxy-1,2,2,6,6-pentamet...
