Characterizations of the as-prepared TC/Apt. a TEM (I) and HRTEM (II) images of TC/Apt. b SEM (I) and zoom-in SEM (II) images of TC/Apt. c Absorption spectra of deionized water (red line), free TC nanosheets (blue line), Apt (yellow line), and the TC/Apt (green line). d Raman spectra of free TC nanosheets (red line), Apt (blue line), and the TC/Apt (green line). e Photoluminescence (PL) spectra of free GO (red line), GO/Apt (blue line), and Apt (green line). f The PL spectra of free TC nanosheets (blue line), Apt (green line), and the TC/Apt (red line). Apt concentration: 500 nM, GO concentration: 200 μg/mL, and TC concentration: 200 μg/mL
