Abstract

Quantum dots (QDs), a novel category of semiconductor materials, exhibit extraordinary capabilities in tuning optical characteristics. Their emergence in biophotonics has been noteworthy, particularly in bio-imaging, biosensing, and theranostics applications. Although conventional QDs such as PbS, CdSe, CdS, and HgTe have garnered attention for their promising features, the presence of heavy metals in these QDs poses significant challenges for biological use. To address these concerns, the development of Ag chalcogenide QDs has gained prominence owing to their near-infrared emission and exceptionally low toxicity, rendering them suitable for biological applications. This review explores recent advancements in Ag chalcogenide QDs, focusing on their synthesis methodologies, surface chemistry modifications, and wide-ranging applications in biomedicine. Additionally, it identifies future directions in material science, highlighting the potential of these innovative QDs in revolutionizing the field.

用于近红外生物光子应用的银合卤化物量子点的合成与表面工程。

量子点（QDs）是一类新型半导体材料，在调整光学特性方面表现出非凡的能力。量子点在生物光子学领域的出现值得关注，尤其是在生物成像、生物传感和治疗学应用方面。虽然 PbS、CdSe、CdS 和 HgTe 等传统 QDs 因其前景广阔的特性而备受关注，但这些 QDs 中重金属的存在给生物应用带来了巨大挑战。为了解决这些问题，砷化镓 QDs 因其近红外发射和极低的毒性使其适用于生物应用而备受瞩目。这篇综述探讨了银质 Chalcogenide QDs 的最新进展，重点关注其合成方法、表面化学修饰以及在生物医学中的广泛应用。此外，它还指出了材料科学的未来发展方向，强调了这些创新型 QDs 在彻底改变该领域的潜力。
