Molecular Gold Nanoclusters for Advanced NIR-II Bioimaging and Therapy
Small thiolate-protected gold molecular clusters have gained significant interest in research due to their unique size-dependent properties. Their molecular to nanoscale sizes lead to distinctive quantum confinement effects, resulting in a discrete electronic energy band gap structure and molecule-like properties, including HOMO–LUMO electronic transitions, enhanced photoluminescence, and intrinsic magnetism and chirality. Near-infrared II (NIR-II, 1000–3000 nm) emissive gold clusters have emerged as a fascinating class of nanomaterials that are well-suited for biomedical applications. The unique combination of stability, biocompatibility, and tunable emission properties position them as valuable tools for high-resolution and deep-tissue imaging, with potential real-world applications ranging from disease diagnostics and prognosis to therapeutics. In this review, we focus on the NIR-II photoluminescence properties of gold molecular clusters for preclinical in vivo NIR-II imaging of vasculature, brain, kidney, liver, and gastrointestinal organs, and molecular targeted tumor imaging and theranostic treatment. The imaging capabilities combined with fast excretion and a high safety profile make molecular gold clusters highly promising for clinical translation.
期刊介绍:
Chemical Reviews is a highly regarded and highest-ranked journal covering the general topic of chemistry. Its mission is to provide comprehensive, authoritative, critical, and readable reviews of important recent research in organic, inorganic, physical, analytical, theoretical, and biological chemistry.
Since 1985, Chemical Reviews has also published periodic thematic issues that focus on a single theme or direction of emerging research.
