Combination of ternary complex of NAB/β-CD in the presence of PVP & LSPR of Au-NPs.
Develop. of a colorimetric method for the determination of NAB based on Au-NPs LSPER.
The ratio of absorbance intensity at 650 to 520 nm is proportional to NAB concentration.
Successful application of the method for determination of NAB in various samples.
