使用金纳米颗粒（三角形纳米片或纳米球聚集体）作为成像剂，证明了具有双光子诱导的光致发光的细胞成像。在与酵母细胞缀合时，金纳米片表现出可见的双光子激发发光，其可以通过双光子激光扫描显微镜检测。细胞可以是干燥的（在空气中）或活的（在水中）。
Cell imaging with two-photon-induced photoluminescence is demonstrated using gold nanoparticles (either triangular nanoplates or nanosphere aggregates) as imaging agents. On being conjugated to yeast cells, gold nanoplates exhibit visible two-photon excited luminescence that can be detected by two-photon laser scanning microscopy. The cells can be either dried (in the air) or alive (in water).
