Graphical Abstract
  • MSCs are potentially safe to use in long-term tumour imaging and cell tracking experiments. Although there is a great deal of concern about the potential hazards of QDs containing heavy metals, the toxicity of QDs is a topic of controversy. The toxicity and ecotoxicity of QDs is studied at various

Furthermore, it has been decided to also evaluate the ecotoxicity potential and the human toxicity potential related to the two
