Modified apple polysaccharide capped gold nanoparticles for oral delivery of insulin

The study entailed formulation of gold nanoparticles (AuNPs) upon reduction of chloroauric acid by modified apple polysaccharide (MAP). AuNPs were conjugated with insulin (INS) for its oral delivery to treat type 1 diabetes mellitus (DM). The size of MAP conjugated AuNPs loaded with INS was 124 ± 8.55 nm with zeta potential −10.5 ± 0.54 mV. The animal study carried out in streptozotocin induced rat model revealed that AuNPs conjugated insulin...
