PLGA Nanospheres Loaded with Gold

Gold nanoparticles are encapsulated within PLGA nanospheres
Dimensional profiles of PLGA nanocarriers, with mean sizes ranging from 100 to 192 nm
FE-SEM image of PLGA nanospheres confirming excellent dispersion and the absence of aggregation after metallic loading
Transmission electron micrograph revealing the internal structure and spherical morphology of the polymeric nanocarriers
Nanospheres are engineered using PLGA polymers to encapsulate gold nanoparticles
PLGA nanocarriers show strong negative surface charge, reaching up to -53 mV with gold loading.
Energy-dispersive X-ray (EDX) spectrum confirming the uniform distribution of gold (Au X-ray signals) within the polymer matrix
High-resolution TEM detail where gold nanoparticles are visible as dark "black dots" stably encapsulated inside the PLGA spheres
