Demonstrates the enhanced fluorescence response of defect-induced SWCNTs to organophosphates, indicating their potential for advanced sensing applications.
Key Points
To understand how oxygen defects in single-walled carbon nanotubes influence their fluorescence response to organophosphates in a corona-dependent manner.
Introduced oxygen defects into (6,5) single-walled carbon nanotubes (SWCNTs).
Examined fluorescence response in sodium cholate and lipid-polyethylene glycol dispersions.
Utilized Fourier transform infrared and high-resolution X-ray photoelectron spectroscopy for analysis.
Defect-induced SWCNTs show amplified fluorescence response to organophosphates in sodium cholate dispersions.
Pristine SWCNTs exhibit a rapid decrease in fluorescence intensity upon organophosphate exposure.
In lipid-polyethylene glycol dispersions, defect-induced SWCNTs have a gradual fluorescence enhancement, even in seawater.
