Health and environmental protection issues have become major focus areas in many research and development projects. In this context, recent MTT cytotoxicity assessments performed on carbon-doped MoSe2 nanoparticles have indicated that they exhibit excellent biocompatibility. Therefore, these nanoparticles have attracted considerable interest from researchers worldwide. Herein, we report the successful synthesis of carbon-doped MoSe2 nanoparticles using an ultrasonic method to enhance their lubrication effect for use as oil additives. Carbon-doped MoSe2 nanoparticles are smaller than untreated MoSe2 nanoparticles and can easily access the contact area to form a tribofilm, reducing the friction coefficient and generating less wear. Moreover, carbon-doped MoSe2 nanoparticles and waste water prepared with the nanoparticles display excellent biocompatibility. Hence, they can be used in practical applications such as oil additives.
