Biosensors can be developed using quantum dots (QDs). An inorganic nucleus with organic molecules attached to its surface is referred to as a QD, and they are a type of new fluorescent nanomaterial. QDs possess unique excellent optical properties and chemical properties, including broad excitation spectra, adjustable particle sizes, confined emission spectra, emission of multiple fluorescence colors, superior signal brightness, and extended fluorescence lifetime. QDs have abundant functional groups, which make it easy to form hybrid nanomaterials that perform analytically well. With functionalized sensing systems, we can detect metal ions, biomarkers, and antibiotics sensitively and selectively through the hybridization of QDs with nanomaterials. In this chapter, we first introduce the research trends in the application of QDs and then discuss their surface modification for biological applications.

Metal-organic frameworks are materials with a lot of potential in various analytical applications, particularly in preparing samples due to their varied structure topology, good thermostability, high surface area, permanent nanoscale porosity, and adjustable pore size. However, their chemical and thermal stabilities are currently a significant limitation in the field of extraction. These materials derived from metal-organic frameworks have demonstrated good extraction performance when it comes to environmental pollutants. In this chapter, we provide a critical overview of the applications of metal-organic frameworks for the extraction, such as stir bar solid extraction, micro-solid-phase extraction, solid-phase microextraction, magnetic solid-phase extraction, and solid-phase extraction.
