This review captures the synthesis, assembly, properties, and applications of copper chalcogenide NCs, which have achieved significant research interest in the last decade due to their compositional and structural versatility. The outstanding functional properties of these materials stems from the relationship between their band structure and defect concentration, including charge carrier concentration and electronic conductivity character, which consequently affects their optoelectronic, optical, and plasmonic properties. This, combined with several metastable crystal phases and stoichiometries and the low energy of formation of defects, makes the reproducible synthesis of these materials, with tunable parameters, remarkable. Further to this, the review captures the progress of the hierarchical assembly of these NCs, which bridges the link between their discrete and collective properties. Their ubiquitous application set has cross-cut energy conversion (photovoltaics, photocatalysis, thermoelectrics), energy storage (lithium-ion batteries, hydrogen generation), emissive materials (plasmonics, LEDs, biolabelling), sensors (electrochemical, biochemical), biomedical devices (magnetic resonance imaging, X-ray computer tomography), and medical therapies (photochemothermal therapies, immunotherapy, radiotherapy, and drug delivery). The confluence of advances in the synthesis, assembly, and application of these NCs in the past decade has the potential to significantly impact society, both economically and environmentally.

“…The generation of aryl radicals from bench-stable aryl halides typically involves a strong base, such as potassium tert-butoxide, or nucleophiles under ultraviolet (UV) (λ ex ≤ 350 nm) irradiation (cf., S RN 1 reaction mechanism). 44 Murphy and co-workers 45 have shown that the electron transfer to aryl halides could be possible from highly reactive neutral organic reducing agents, such as N 2 ,N 2 ,N 12 ,N 12tetramethyl-7,8-dihydro-6H-dipyrido [1,4]diazepine-2,12-diamine under UV-A (365 nm) irradiation. Recently, Konig and co-workers 46 have shown that the reduction of aryl halides is possible using excited doublet states of organic radicals available via consecutive photoinduced electron-transfer (conPET) processes.…”

In the recent past, visible-light-mediated photoredox catalysis has made a huge impact on the development of new synthetic methods under very mild and ecologically benign conditions. Although semiconductor nanocrystals or quantum dots (QDs) possess suitable optoelectronic and redox properties for photoredox catalytic applications, surprisingly, their use for the activation of challenging chemical bonds in the synthesis of organic molecules is little explored. We report here the application of ZnSe/CdS core/shell QDs for the synthetically important photoredox catalytic activation of carbon–halogen bonds in dehalogenation and C–H arylation reactions using (hetero)aryl halides as bench-stable inexpensive bulk starting materials, under very mild reaction conditions. The outstanding catalytic activity of ZnSe/CdS core/shell QDs is a direct consequence of the high specific surface area and homogeneity of QDs in solution and their high photostability toward oxidation.

“…Quantum dots can be synthesized as colloids, and often provide a high photoluminescence quantum yield and consistency of photoluminescence compared to conventional fluorophores. Quantum dots have narrow band emissions, [16] which, along with their broad excitation wavelengths, offer an advantage in multicolor imaging [17] and multiplexed sensing applications. Figure 2 shows the recent modifications on quantum dots that have enabled their in vivo and in vitro applications.…”

Nanostructured materials can now be engineered with great precision and complexity as a result of advances in design and fabrication, and offer distinct advantages in many biosensing and biomedical applications. The materials most widely used in this field are semiconductors and noble metals. Each offers multiple length scales of nanostructuring that program their physicochemical properties for different biosensing applications. Here, nanostructured materials and their applications are reviewed together with semiconductors and noble metals, as well as hybrid materials that unite these two classes—all with the goal of linking performance characteristics to applications in biomedicine.
