In vivo three-dimensional molecular imaging with Biosensor Imaging of Redundant Deviation in Shifts (BIRDS) at high spatiotemporal resolution.
镧系(III)离子(如 Tm3+)与环状螯合物(如 DOTMA4-)形成的复合物可产生对生理参数(如温度)敏感的光谱信号。由于这些镧系基大环探针的非交换质子弛豫时间仅数毫秒,化学位移成像(CSI)可实现快速数据采集。BIRDS(Biosensor Imaging of Redundant Deviation in Shifts)利用...
