Quantum dots (Figure 1.1d) are the class of semiconductor nanoparticles with unique photo‐physical properties. Usually, quantum dots have a core/shell structure composed of molecules of various metals like technetium, cadmium selenide, zinc, indium, tantalum, etc. (Medintz et al. 2005; Wang et al. 2019). The most commonly used, commercially available quantum dots contain a cadmium selenide core covered with a zinc‐sulfide shell. The core‐shell complex is generally encapsulated in a coordinating ligand and an amphiphilic polymer (Gao et al. 2004). Due to unique optical properties, quantum dots have been used as dominant classes of fluorescent imaging probes for various biomedical applications (Núñez et al. 2018).
