WebAuNPs in citrate buffer are negatively charged and have good stability with a zeta potential of −23.81±8.43 mV. The zeta potential of the PEP-AuNPs increased with increases in initial concentration and became positively charged at 15 μM, which signifies that there was enough peptide to change the charge of the conjugated particles. Webmodifier is used.7 Because citrate is a very poor absorbing analyte, a mobile phase with a strong UV-absorbing chromophore is required for indirect UV detection.9 Chalgari and Tan described a citrate assay for some pharmaceutical dosage forms with USP monographs that uses ion chromatography (IC) with indirect photometric detection. popheap
