Analytical Applications of Photoluminescent Nanomaterials
Abstract: Gold, silver, copper, and carbon photoluminescent nanomaterials have become popular sensing materials. Having advantages of long life time, large Stokes shift, stability, ease in preparation/conjugation, and biocompatibility, these nanomaterials have been employed to develop sensitive and selective sensing systems for the detection of metal ions and anions. In addition, they have been used in cell imaging. In my talk, I will present their preparation strategies, optical properties, and applications. To highlight practicality of these nanomaterials, several interesting sensing systems for the detection of mercury, silver, cyanide, and nitrite will be emphasized. Potential use of carbon dots as nanodrugs and in cell imaging will be also discussed.
