The development of new functional nanomaterials for the diagnosis and therapy of cancer has attracted increasing attention in recent years. For effective cancer therapy, it is important to develop a new theranostic system based on unique nanomaterials that is capable of responding to a local tumor environment or external stimuli such as temperature, pH, magnetic field, light, etc. One of the most promising materials is nanocrystalline tungsten oxide (WO3), a semiconductor with a wide n-type bandwidth with a chemical type of chromium, which gives it unique photocatalytic properties. Within the framework of this work, we studied the effect of polyvinylpyrrolidone (PVP) - stabilized WO3 nanoparticles on the metabolic and proliferative activity of normal and malignant human cells in vitro .
