The shape of titanium dioxide nanomaterials modulates their protection efficacy against ultraviolet light in human skin cells

Skin protection against ultraviolet (UV) radiation is necessary to reduce sunburn damage (erythema) and has been recognized as an important preventive measure against the development of cancer. Many sun-blocking pharmaceutical products are based on titanium dioxide nanomaterials (TiO2 NMs) due to their UV barrier properties. This study aimed to assess if the UV protective efficiency of TiO2 NMs depends on their shape. We prepared TiO2 nanowires...
