胶体半导体量子点(QD)长期以来已经建立了它们的多功能性和实用性来可视化生物相互作用。在单粒子水平上,与有机染料分子或荧光蛋白相比,QD表现出优异的光物理特性,但是对于QD的表现,对于超出衍射量以外的成像性能,这些基本特征中的哪一个仍然是一个开放的问题。限制。在这里,与用有机荧光团标记的神经元相比,我们在QD标记的神经元中可实现的定位精度显着增强。此外,我们确定了负责此增强的QD的关键光物理参数,并将这些参数与用于超分辨率成像的常用荧光团的报告值进行了比较。
Colloidal semiconductor quantum dots (QDs) have long established their versatility and utility for the visualization of biological interactions. On the single-particle level, QDs have demonstrated superior photophysical properties compared to organic dye molecules or fluorescent proteins, but it remains an open question as to which of these fundamental characteristics are most significant with respect to the performance of QDs for imaging beyond the diffraction limit. Here, we demonstrate significant enhancement in achievable localization precision in QD-labeled neurons compared to neurons labeled with an organic fluorophore. Additionally, we identify key photophysical parameters of QDs responsible for this enhancement and compare these parameters to reported values for commonly used fluorophores for super-resolution imaging.
