Encapsulation Efficiency of APS

Volume of APS EE (%)
50 83.49±1.107
100 54.89±2.07
150 36.66±1.705
200 30.03±2.117

Notes: The initial volume of APS (10 mg/mL) was optimized for stable synthesis of APS/AuNR/PLGA-PEG NPs: 100 μL of APS with 50 μL of AuNRs (1 g/mL) was the optimal combination.

Abbreviations: APS, astragalus polysaccharide; AuNRs, gold nanorods; EE, encapsulation efficiency; PLGA, poly(lactic-co-glycolic) acid; PEG, polyethylene glycol; NPs, nanoparticles.
