Abstract

---

Fluorescent nanomaterials, including gold nanodots (Au NDs), DNA templated silver nanoclusters (DNA-Ag NCs), and carbon dots (C-dots), have become useful sensing materials because of their interesting optical properties and biocompatibility. In this talk, the author will briefly discuss several green approaches to the preparation of the three types of photoluminescent nanomaterials and their analytical applications. C-dots prepared from used tea, ground coffee, leaves, and ginger are highlighted. Detection of metal ions using the as-prepared photoluminescent nanomaterials is emphasized. Advantages and disadvantages of the three types of photoluminescent nanomaterials are discussed.
