“…Chemiluminescence (CL) is one of the methods largely applied in pharmaceutical analysis due to the properties of high sensitivity, low cost and being environmental friendly (26)(27)(28). The interesting work published by Zhang et al (29,30) showed that the CL method could be used to study the interaction between drugs and proteins through coupling to simple technologies such as microdialysis.…”

In acidic media, ibuprofen substantially enhanced the weak chemiluminescence (CL) produced by sodium sulfite and potassium permanganate. The increased signals were linearly correlated with ibuprofen concentrations ranging from 1.2 × 10(-3) to 4.8 μM, with a detection limit of 4.8 × 10(-4) μM. Two ultrafiltration (UF) membranes were used to construct a unit for trapping 0.15 and 0.75 μM human serum albumin (HSA) and coupled online with the CL system. At low HSA concentrations, the numbers of bound molecules per binding site were calculated to be 0.9 for Sudlow site I and 6.2 for Sudlow site II. The association constants on these binding sites were 5.9 × 10(5) and 3.4 × 10(4) M(-1), respectively. Our CL-UF protocol presents a rapid and sensitive method for studies on drug-protein interaction.

“…The PO–CL reaction is very sensitive to basic catalysts and must be carried out under acidic conditions (pH 5–9) The effect of pH values on the CL reaction of TCPO–H 2 O 2 –AgNPs was investigated and the result is shown in Fig. , from which it can be seen that the CL intensity increased with increasing of pH in the range 5–8.…”

The method is based on the fact that dipyridamole can enhance the chemiluminescence (CL) emission from the redox reaction of bis (2,4,6-tricholorophenyl) oxalate (TCPO) with H(2)O(2) in the presence of silver nanoparticles (AgNPs). The CL reaction mechanism was discussed. The effect of concentrations of TCPO, H(2)O(2), AgNPs and pH value on the CL reaction were investigated. Under the optimum conditions, the linear dynamic range was 1.0-1000 × 10(-9) g/mL and the detection limit (3σ) was 9 × 10(-10) g/mL. The relative standard deviation (RSD) was 4.8% for 1.0 × 10(-9) g/mL dipyridamole (n = 7). The proposed method has been successfully applied to the determination of dipyridamole tablets and the recovery was 99-103%.
