研究目的
Investigating the efficiency of inorganic Zn3N2 nanoparticles for labelling plant and animal cells towards imaging applications with negligible toxicity.
研究成果
Zn3N2 colloidal nanoparticles were successfully prepared at room temperature and showed significant fluorescence enhancement when integrated with organic dyes. The nanoparticles demonstrated potential for bioimaging and biosensor applications due to their negligible toxicity and enhanced emission intensity.
研究不足
The study focuses on the in vitro application of Zn3N2 nanoparticles for bioimaging and biosensor applications. The in vivo toxicity and long-term stability of these nanoparticles need further investigation.
