Magnetic nanoparticles are among the most important carriers for the delivery of anticancer drugs. Four important noncovalent interactions between tirapazamine anticancer drug (TPZ) and magnetic nanoparticle Fe 6 (OH) 18 (H 2 O) 6 (MNP) have been examined by using density functional theory (DFT). Important interactions are those where the drug approaches the magnetic nanocarrier via NH 2 (MNP/TPZ1), NO (MNP/TPZ2-3) and intraring N-atom (MNP/TP4) functional groups. The negative values of binding energies and quantum molecular descriptor showed that these interactions contribute to the stability of the system. By increasing the temperature, TPZ can bond to MNP through NH 2 (NH 2 mechanism), NO (NO mechanisms) and intraring N-atom (N mechanism) functional groups. The activation parameters of four mechanisms were evaluated using quadratic synchronous transit method. Relative energies indicate that the product of the NH 2 mechanism is more stable but is produced more slowly (thermodynamic product). In contrast, the products of the NO mechanisms are kinetic products.

The growing use of nanoparticles in the analytical process in recent years has set a new trend towards the simplification of analytical methods and improvement of their performance. Miniaturization and nanotechnology have allowed new analytical challenges to be met. Hybrid nanoparticles in particular possess exceptional properties enabling further improvement of analytical methods. Despite the continuous developments in their synthesis and characterization, hybrid nanomaterials have scarcely been used in analytical chemistry, however. This paper discusses the analytical potential of hybrid nanoparticles in terms of their special characteristics and properties, and describes their analytical applications.
