Determination of naphazoline hydrochloride in biological and pharmaceutical samples by a quantum dot‐assisted chemiluminescence system using response‐surface methodology

Abstract: A simple and highly sensitive chemiluminescence (CL) method is reported for the determination of naphazoline hydrochloride (NH). It was found that the weak CL from the reaction of luminol and KIO4 in an alkaline medium could be highly amplified by cysteine-capped cadmium telluride quantum dots (QDs) and the enhanced CL was effectively quenched by NH and this finding was utilized as a basis for the determination of NH. The QDs were synthesized in aqueous medium and characterized by X-ray diffraction (XRD), tran… Show more

“…Serum samples were prepared according to a reported procedure [19]. In brief, a 1.00 mL aliquot of serum was transferred into a centrifuge vessel and 2.00 mL of 0.1 M Ba(OH) 2 and 2.00 mL of 0.1 M ZnSO 4 were added to precipitate the proteins.…”

“…The response surface methodology is a clever combination of techniques that take root in mathematics and statistics used for solving various optimization problems. It helps researchers find the global optimum conditions of the system rather than any likely local optima [19][20][21]. The present study takes advantage of central composite design (CCD), a widely used version of RSM [19,20], for optimizing the analysis conditions in terms of achieving the largest possible ∆F values.…”
