Abstract:
Since chemotherapy suffers many limitations related to side effects of anticancer drugs (e.g. cisplatin - CDDP), nanoparticles are probed as carriers in targeted drug delivery. Gold nanoparticles (AuNPs) are broadly investigated due to their biocompatibility, nontoxicity, and tunable surface. Despite many AuNPs-cisplatin systems (AuNP-CS) reports found in the literature, only a few include studies of their synthesis and formation efficiency using analytical tools providing simultaneously qualitative and quantitative analytical information. Therefore, this research continues our previous study of AuNP-CS formation investigated by capillary electrophoresis with inductively coupled plasma mass spectrometry (ICP-MS). Namely, it presents the analogical approach but employs the coupling of another separation technique: isocratic reversed-phase high-performance liquid chromatography. The study concerns the difficulties of analytical method optimization path and contains a discussion of the observed problematic issues related to the analysis and preparation of AuNP-CS. Moreover, the presented work confronts the performance and applicability of both tools for the scrutiny of AuNP-CS, especially considering the comparison of their resolution power.
