Visualizing nanoplastics-metal ions co-exposure stress with a NIR biothiols responsive fluorescent probe

Key Points

• The aim is to visualize the toxic effects of combined nanoplastics and heavy metal ions using a specific imaging tool.
• Developed a fluorescent probe responsive to biothiols for visualization.
• Performed in situ imaging to assess combined exposure.
• Utilized co-exposure models to understand stress effects.
• Successfully demonstrated imaging of co-exposure stress in real-time.
• Identified the combined toxic effects of nanoplastics and metal ions.
• Provided a new method for studying environmental contaminants.
