UV-Vis spectra of MWCNT-EDA (black line) and upon TPPS addition (red line), and 1 day after mixing (blue line) (A), and of MWCNT-EPA (black line), upon TPPS addition (red line), and 1 day after mixing (blue line) (B). Experimental conditions: [TPPS] = 5 µM; MWCNT-EDA or MWCNT-EPA = 0.02 mg/mL; 10 mM citrate buffer at pH 2.4; PL protocol; T = 298 K.
