Abstract

Carbon nanoparticles, otherwise known as c-dots are a relatively new breakthrough in science with possible prospects in chemical sensing, bio imaging, and other biological applications. Due to their low toxicity levels and various top-down and bottom-up synthesis, c-dot research is high in demand. However, while carbon dots are becoming more prevalent, their generally low quantum yields, in addition to their unclear morphologies have not allowed them to outperform their metal semiconductor nanoparticle rivals. The composition of carbon dots is still widely-unknown and has called for further investigation, although they are mostly comprised of carbon, oxygen, and nitrogen. The use of injection of carbon nanoparticles on 6dpf zebrafish larvae was previously considered in addition to previous work on larvae soaking. Herein, we explored top-down and bottom-up approaches to synthesize black carbon dots, human transferrin conjugate carbon dots, and orange carbon dots. We then soaked zebrafish larvae in various concentrations to target calcified bone thus proving possible applications for drug delivery with human transferrin conjugate c-dots. After treatment, bio imaging occurred on 7dpf-9dpf where fluorescent targeted calcified bones were observed in 3.4 mg/mL, and 5 mg/mL concentrations of black carbon dots in addition to 5 mg/mL transferrin conjugate c-dots. Previous studies using soaking methods have only shown targeted organs and tissue through soaking methods with lower concentrations carbon dot solutions. Using our methods and treatments, we were able to target calcified bones. This was exhibited in soaking that occurred in 3.4, 5, and 5 mg/mL conjugated human transferrin black carbon dot solutions.
