“…Since BSA is a very popular protein template in the synthesis of metal nanoclusters, many other BSA-Cu NCs with blue luminescence were subsequently reported [ 12 , 19 , 20 ]. Apart from proteins, thiolate ligands were also used widely to prepare Cu NCs [ 17 , 21 , 22 , 23 , 24 ]. In this category, glutathione (GSH) was a typical one [ 25 , 26 , 27 ].…”

“…And the recovery rates of the target analytes ranged from 97%to 108% with the RSD smaller than 3.5%. Through the one-pot galvanic reduction approach, gold-copper nanoclusters capped by cysteamine (CA-AuCu NCs) were prepared for the detection of chromium(VI) and dopamine, the levels of which are critical to the development of severe diseases [ 23 ]. The distinct optical properties of this probe made it an ideal candidate in the determination of the target analytes in real samples, such as tap water, lake water, sea water and human urine.…”

“…Under certain circumstance they tend to form emissive nanostructures, which are comparable with recently developed nanomaterials, such as nanocluster, quantum dots, MOFs, etc. [ 112 , 113 , 114 , 115 , 116 ]. By attaching biocompatible units, such as peptides, polypeptide and inorganic nanostructures, toxicity of the AIE-active pyrene derivatives can be reduced to be comparable to other therapeutic nanomaterials, such as conjugated polymers, MOFs, carbon-dots, nanoclusters, etc.…”

Aggregation-induced emission (AIE) is a unique research topic and property that can lead to a wide range of applications, including cellular imaging, theranostics, analyte quantitation and the specific detection of biologically important species. Towards the development of the AIE-active materials, many aromatic moieties composed of tetraphenylethylene, anthracene, pyrene, etc., have been developed. Among these aromatic moieties, pyrene is an aromatic hydrocarbon with a polycyclic flat structure containing four fused benzene rings to provide an unusual electron delocalization feature that is important in the AIE property. Numerous pyrene-based AIE-active materials have been reported with the AIE property towards sensing, imaging and theranostics applications. Most importantly, these AIE-active pyrene moieties exist as small molecules, Schiff bases, polymers, supramolecules, metal-organic frameworks, etc. This comprehensive review outlines utilizations of AIE-active pyrene-based materials on the imaging and theranostics studies. Moreover, the design and synthesis of these pyrene-based molecules are delivered with discussions on their future scopes.

Diamond electrodes have long been a well-known candidate in electrochemical analyte detection. Nano- and micro-level modifications on the diamond electrodes can lead to diverse analytical applications. Doping of crystalline diamond allows the fabrication of suitable electrodes towards specific analyte monitoring. In particular, boron-doped diamond (BDD) electrodes have been reported for metal ions, anions, biomolecules, drugs, beverage hazards, pesticides, organic molecules, dyes, growth stimulant, etc., with exceptional performance in discriminations. Therefore, numerous reviews on the diamond electrode-based sensory utilities towards the specified analyte quantifications were published by many researchers. However, reviews on the nanodiamond-based electrodes for metal ions and anions are still not readily available nowadays. To advance the development of diamond electrodes towards the detection of diverse metal ions and anions, it is essential to provide clear and focused information on the diamond electrode synthesis, structure, and electrical properties. This review provides indispensable information on the diamond-based electrodes towards the determination of metal ions and anions.
