Description

Application

• Preparation of One-Emission Nitrogen-Fluorine-Doped Carbon Quantum Dots and Their Applications in Environmental Water Samples and Living Cells for ClO(-) Detection and Imaging.: This study illustrates the role of ammonium citrate tribasic in synthesizing nitrogen-fluorine-doped carbon quantum dots. These quantum dots are used for sensitive detection and imaging of chlorite ions in environmental water samples and living cells, demonstrating a novel application in environmental monitoring and biomedical imaging (Zhang et al., 2023).


• High quantum yield nitrogen and boron co-doped carbon dots for sensing Ag(+), biological imaging and fluorescent inks.: Ammonium citrate tribasic is used here to facilitate the doping process in the synthesis of high quantum yield carbon dots. These dots have applications ranging from heavy metal ion sensing in environmental samples to advanced imaging techniques in biological systems and the creation of fluorescent inks (Cheng et al., 2021).


• Optimization of Copper Stain Removal from Marble through the Formation of Cu(II) Complexes in Agar Gels.: This research employs ammonium citrate tribasic in a novel method for removing copper stains from marble. The study explores the chelating properties of ammonium citrate tribasic to form stable Cu(II) complexes, offering a conservation technique for historical artifacts and buildings (Sansonetti et al., 2021).


• A facile microwave-assisted synthesis of highly crystalline red carbon dots by adjusting the reaction solvent for white light-emitting diodes.: Ammonium citrate tribasic is instrumental in this study for synthesizing red carbon dots under microwave conditions. The dots are used in the development of white light-emitting diodes, showing potential for applications in display technologies and lighting (Lan et al., 2020).
