Plasmonic resonance energy transfer (PRET) from a Au nanosphere (AuNS) to a quantum dot (QD) is discovered at the single particle level. A homogenous immunoassay based on this PRET is verified using a prostate specific antigen (PSA) as an example. The limit of detection of the PSA is determined to be 0.2 fM.
金纳米球（AuNS）到量子点（QD）的等离子体共振能量转移（PRET）在单粒子水平上被发现。基于这种 PRET 的均相免疫测定法用前列腺特异性抗原（PSA）作为一个例子得到了验证。PSA 的检测限被确定为 0.2 fM。
