“Background Platinum (Pt) is a noble metal with unique physiological and chemical properties widely used in chemistry, physics, biology, and medicine. Regarding the biological activities of Pt, it is known that Pt compounds have the ability to arrest the cell cycle [1, 2] and cause DNA strand breaks. The DNA damage is caused by Pt ions, which attach to N7 sites of DNA guanine bases and, after hydrolysis of Pt-Cl bonds, form adducts with the DNA double helix [2, 3]. These properties of Pt are exploited in cancer therapy in the form of antineoplastic drugs to treat different types of cancer such as head, neck, brain [4], testicular, bladder, ovarian, or uterine cervix carcinomas [5]. However, toxic side effects of Pt-based drugs are major drawbacks in cancer therapy [6, 7]. Nanotechnology has introduced possibilities for using alternate forms of elements – nanoparticles. Nanoparticles have unique physiochemical features

because of their small size (<100 nm), large surface-to-mass ratio, exceptional quantum characteristics [8], and consequently unique biological properties. Smaller nanoparticles can move across cellular and also nuclear Pregnenolone membranes and are able to penetrate cells and intracellular structures, and target defined points within the body [9, 10]. Platinum nanoparticles (NP-Pt) have recently elicited much interest because of their physicochemical properties such as catalytic activity and high reactivity [11]. NP-Pt, as metal structures (Pt0), differ significantly from platinum salts and have quite different chemical properties when administered to an organism. They are a very limited source of ions, and consequently, the process of forming platinum salts is very slow and restricted. However, the solubility and, consequently, the bioavailability of NP-Pt depend on their size [12].
