David Freedman these sensors can be categorized as low molecular weight probes or genetically encoded proteins. Based on the nature of the signal emitted by these sensors, they can be divided into two groups: (1) nonratiometric sensors whose fluorescence intensity reports and (2) ratiometric sensors, with [斗争 发表于 2025-3-27 04:55:33
