In this manuscript, a near-infrared (NIR) light-breakable amphiphilic block copolymer N-succinyl-N′-4-(2-nitrobenzyloxy)-succinyl-chitosan micelles (SNSC), containing light-sensitive triggering group 2-nitrobenzyl alcohol on the hydrophobic block, was developed. The UV–Vis absorption spectra, Fourier Transform Infrared (FTIR) spectra, and 1 H nuclear magnetic resonance ( 1 H NMR) spectra...
Heparin-conjugated hyaluronan (HA-Hp) microgels with different heparin content, i.e., 1%, 5% and 10% (w/w), were synthesized by an inverse emulsion polymerization technique for the controlled release of bone morphogenetic protein-2 (BMP-2). A heparin conjugation percentage of about 90% was obtained by elemental analysis. Hyaluronan microgels showed a smooth surface and dense network, whereas HA-Hp...
