Since the concept of surface plasmon amplification by stimulated emission of radiation (SPASER) was proposed in 2003, great progresses have been made on two kinds of plasmonic nanolasers, namely SPASER device and SPASER nanoparticle. In comparison, SPASER nanoparticle, with ultra-narrow emission line, small size, and good biocompatibility, is a kind of promising luminescent nanoprobe and has a bright application prospect in biomedical imaging and sensing. Hence, it is gradually becoming an attractive research hotspot in the world. However, as the research on SPASER nanoparticle is still in its infancy, there are still lots of problems to be solved before it is widely applied. In this paper, the latest research advances of SPASER nanoparticles and their biological applications are reviewed. Besides existing problems, challenges and opportunities of SPASER nanoparticles as next generation luminescent nanoprobes are discussed as well.

SPASER 作为生物应用的纳米探针：现状和机遇

自2003年提出受激发射表面等离子体放大（SPASER）的概念以来，两种等离子体纳米激光器即SPASER器件和SPASER纳米粒子已经取得了很大进展。相比之下，SPASER纳米粒子具有发射线超窄、尺寸小、生物相容性好等优点，是一种很有前途的发光纳米探针，在生物医学成像和传感方面具有广阔的应用前景。因此，它正逐渐成为世界上颇具吸引力的研究热点。然而，由于SPASER纳米粒子的研究还处于起步阶段，在其被广泛应用之前还有很多问题需要解决。本文综述了SPASER纳米粒子的最新研究进展及其生物学应用。除了存在的问题，
