Abstract

Exposure to ultraviolet (UV) and ionizing radiation (X-ray) can induce DNA damage, promoting mutagenic and cytotoxic processes. In this context, carbon-based nanomaterials stand out as biocompatible nanomaterials, highly soluble in water and with adjustable optical properties. In this work, we reported the obtention of carbon dots (CDs) based in citric acid + urea (CDU) or citric acid + thiourea (CDT) as well as investigated the protector potential of CDs in DNA damage against exposure to UV and X-ray radiation.
