近年来，基于上转换纳米颗粒(UCNP)的探针研究取得了重大进展。与传统的荧光探针(如有机染料、金属络合物或无机量子点)相比，UCNPs具有非自发荧光、化学稳定性高、光穿透深度大、寿命长、对样品的损伤小等优点。本文重点介绍了自2014年以来，稀土掺杂UCNPs作为生物检测高效探针的最新研究成果。首先介绍了UCNP的上转换机理和发光共振能量传递过程，然后详细总结了基于UCNP的生物检测的研究现状，包括无机离子、气体分子、活性氧物种、硫醇和硫化氢的检测。
Significant progress on upconversion‐nanoparticle (UCNP)‐based probes is witnessed in recent years. Compared with traditional fluorescent probes (e.g., organic dyes, metal complexes, or inorganic quantum dots), UCNPs have many advantages such as non‐autofluorescence, high chemical stability, large light‐penetration depth, long lifetime, and less damage to samples. This article focuses on recent achievements in the usage of lanthanide‐doped UCNPs as efficient probes for biodetection since 2014. The mechanisms of upconversion as well as the luminescence resonance energy transfer process is introduced first, followed by a detailed summary on the recent researches of UCNP‐based biodetections including the detection of inorganic ions, gas molecules, reactive oxygen species, and thiols and hydrogen sulfide.
