Nanomaterials communication inside the living organism

Abstract Nanotechnology (NT) is an the emerging field that brings incredible advantages to society. The potential usage of nano-based materials and products has been tremendously increased in various fields since ancient times. The use of nanomaterials (NMs) is being increased in applications for commercial products, and NT is poised to become a major factor in the world’s economy and part of our everyday lives in the near future. Already hundreds of tonnes of NMs has entered into the environment and this figure is increasing annually. At the same time, some adverse effects also occur concerning human beings and the environment. The toxic effects of NPs may trans-locate into human body exposure through skin, inhalation, injection, ingestion etc.. Some nano-toxicology researchers say that when NMs penetrate into the human body, our human body defence (immune) system becomes less stimulative and suffers from poor recognition. The purpose of this article is to review the current state of knowledge regarding NMs’ toxicity, reasons for toxicity, and precautionary assessment of NMs.
