The measurements of UV-Visible, X-ray diffraction (XRD), Fourier transform infrared (FTIR) and scanning electron microscopy (SEM) have been used to confirm the formation of BO-AgNPs, revealing a prominent absorption band at 450 nm, crystallinity, and an agglomerated morphology having an average particle size of 29 nm. Aspirin in Acifein, Aspirin, Acylpyrin and Disprin tablets was determined through the complexation with BO-AgNPs, revealing a linear range of 1-10 mg/10 mL and limit of detection (LOD) as 0.09, 0.46, 0.69 and 0.99 mg/10 mL, respectively. An average percent recovery for four samples were found to be 90, 99, 101 and 99 % and relative standard deviation (RSD) as 1.6, 0.6, 0.3 and 1.4, respectively. The suggested me...
