Abstract
The distance between an electron and a hole in a semiconductor material is the same as the size of a quantum dot. Much research has been carried out regarding the properties of carbon quantum dots (CQDs). The fact that CQDs are quantum-confined gives them special optical, photochemical, semiconductor, and catalytic properties. So far, scientists in the fields of chemistry, physics, and materials science have discovered ways to make CQDs and have made it easier to control aspects such as particle growth and size, solubility, and the way light emits from them. Human-made quantum dots and their electronic and optical properties are the subjects of this book. A wide variety of physical phenomena have been studied using these dots. CQDs can be used in photovoltaic and laser devices, thin-film transistors, light-emitting diodes, and labels in biology and medicine that glow because of their properties. By killing or preventing the growth of bacteria, antibacterial agents are able to prevent and treat bacterial infections. For example, they target the DNA of the bacteria, or the metabolic processes that go hand-in-hand with them, or the way that bacteria's cell walls are constructed and function. There are several mentions of these carbon dots in this book that kill bacteria.
