Nanocarriers can be used for accurate tumor targeting, but their limited water solubility impedes the stable storage and poses biosafety risks in clinical translation. Here, the authors report water-soluble carbon quantum dots that show stability toward long-term storage and the addition of electrolytes, as well as negligible protein adsorption, immunogenicity, hemolytic activity and toxicity.
