Construction of BODIPY functional ZIF-8 with improved visible light-induced antibacterial activity

Europium- and Black Phosphorus-Functionalized Porphyrin as an l-Arginine Sensor and l-Arginine-Activated PDT/PTT Agent for Bacterial Treatment

“…Next, the combination of Eu in BP@Eu-TCPP was verified by Raman scattering (Figure S3). The Raman spectra of BP@Eu-TCPP not only showed typical peaks of Eu–P from 600 to 800 cm –1 but also gave three characteristic peaks at 355, 428, and 454 cm –1 that are assignable to A g 1 , B 2g , and A g 2 of BP, respectively . Moreover, the ζ-potential of BP was at about −11.58 mV while that of BP@Eu-TCPP was at +3.99 mV (Figure S4a).…”

“…Afterward, the purified bacteria were obtained by centrifugation and washed with deionized water multiple times. The UV–vis spectrum was employed to calculate the concentration of bacteria by measuring the optical density (OD) at 600 nm . Briefly, plate counting was employed by the following experimental procedure.…”

“…The Raman spectra of BP@ Eu-TCPP not only showed typical peaks of Eu−P from 600 to 800 cm −1 but also gave three characteristic peaks at 355, 428, and 454 cm −1 that are assignable to A g 1 , B 2g , and A g 2 of BP, respectively. 34 Moreover, the ζ-potential of BP was at about −11.58 mV while that of BP@Eu-TCPP was at +3.99 mV (Figure S4a). This might provide a basis for the electrostatic binding to bacteria.…”

“…The UV−vis spectrum was employed to calculate the concentration of bacteria by measuring the optical density (OD) at 600 nm. 34 Briefly, plate counting was employed by the following experimental procedure. Prior to mixing the bacterial suspension with the compound's dispersion, 300 μL (10 6 CFU/mL) of bacteria and BP, BP@Eu-TCPP, and BP@Eu-TCPP + L-Arg solution (0, 10, 20, 30, 40, 50, 100 μg/mL) was prepared.…”

Metal–organic framework-based fluorescent probe device DOX-BOD@ZIEF-8 for the detection of doxycycline

“…This case illustrates that the encapsulation of DOX-BOD with ZIF-8 did not affect the crystal structure of ZIF-8 and was reproducible. 36,37 The TGA plot is shown in Fig. 2(b).…”
