• A new graphene-based fluorescent nanoprobe for tumor cell nucleus (GTTNs) was synthesized in our laboratory that penetrates the cell membrane and particularly targets cancer cell nucleus and displays tremendous potential for clinical applications. Although acute and subacute toxicity studies have been conducted on GTTNs, a primary result could be drawn that GTTNs appear to have almost no acute and subacute toxicity. However, as an important part of safety evaluation, the influences on reproductive and offspring developmental toxicity are still absent. In this study, male mice were injected intravenously with GTTNs, and the survival status, histopathology of the testes and epididymides, proliferation and apoptosis of testicular tissue, and sperm motility of mice were measured. To evaluate the short- and long-term fertility in male mice, different male mice resided with untreated female mice on days 1 and 30 after the end of the last treatment, and the offspring health parameters were assessed by measuring pup numbers, body weight, and organ indexes of the pups. The results indicated that GTTNs-exposed male mice retained good fertility, healthy structure of testes and epididymides, and production of healthy sperm. Meanwhile, there were no significant differences between the offspring and the control group. In consideration of GTTNs with broad prospects for biomedical applications, our results contribute a basis for further understanding of its biosafety.
