荧光发射体通过其发射模式同时传输其身份、位置和细胞背景。我们开发了smNet,这是一种用于多路复用单分子分析的深度神经网络,可以高精度地检索这些信息。我们证明,smNet可以提取三维分子的位置,方向和波前失真的精度接近理论极限,因此将允许通过一个单一分子的发射模式的多路复用测量。深度神经网络smNet能够从单分子的发射模式中提取多路复用参数,例如3D位置,方向和波前失真。
A fluorescent emitter simultaneously transmits its identity, location, and cellular context through its emission pattern. We developed smNet, a deep neural network for multiplexed single-molecule analysis to enable retrieving such information with high accuracy. We demonstrate that smNet can extract three-dimensional molecule location, orientation, and wavefront distortion with precision approaching the theoretical limit and therefore will allow multiplexed measurements through the emission pattern of a single molecule. The deep neural network smNet enables extraction of multiplexed parameters such as 3D position, orientation and wavefront distortion from emission patterns of single molecules.
