Inulin, a naturally occurring polysaccharide, was acetylated to make it processable by electrospraying, a facile and single step method for microparticle fabrication. Electrospraying process parameters were optimized for fabrication of spherical and monodisperse indomethacin (IDM) loaded inulin acetate (INA) microparticles.

Poly(D,L-lactide-co-glycolide) (PLGA) is widely used in a variety of tissue engineering and drug delivery applications due to its biodegradability and biocompatibility. But PLGA surfaces are usually hydrophobic which limited the loading and seeding capacities for cells, especially semiadherent immune cells.

While Pd-catalyzed allyl-allyl cross-couplings in the presence of small-bite-angle bidentate ligands reliably furnish the branched regioisomer with high levels of selectivity, cross-couplings in the presence of large-bite-angle bidentate ligands give varying, often unpredictable, levels of selectivity. In a combined computational
