摘要: Biocompatible dysprosia aerogels were synthesized from DyCl3·6H2O and reinforced mechanically with a conformal nano-thin-polyurea coating applied over their skeletal framework. The random mesoporous space of was filled up to about 30% v/v paracetamol, indomethacin, or insulin, the drug release rate monitored spectrophotometrically in phosphate buffer (pH = 7.4) 0.1 M aqueous HCl. uptake study conducted comparatively polyurea-crosslinked silica aerogels, as well as-prepared (native) perforated ordered 7 nm tubes hexagonal packing. Drug nanostructures (silica dysprosia) higher (30–35% w/w) slower (typically >20 h) relative (19–21% w/w, <1.5 h, respectively). data fitted flux equation consisting three additive terms that correspond stored successiv...
