Pyronin B‐Graphene Oxide‐Based Turn‐On Fluorescent Sensors for Fe³⁺ in an Aqueous Medium: Synthesis and Living Cell Application

Abstract

Pyronin B (PyB)-graphene oxide (GO) is reported for metal-ion sensing since it is based fluorescent sensor. PyB-GO nanocomposites are synthesized in aqueous solution by Ultrasonic Homogenizers. The structure of PyB-GO nanocomposites is characterized with X-ray diffraction (XRD),Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, UV-vis spectroscopy and Fluorescence Microscopy. PyB-GO binary system are studied for the sensing ability in the detection of metal ions as a fluorescent sensor. It shows high sensitivity and selectivity for Fe 3 + metal ions in aqueous medium as a result of the spectroscopic data.[a] Dr.
