Cyanine7 for Molecular Sensors PH/Ion/Oxygen Sensors

The application of Cyanine7 in molecular sensors is mainly used to detect the presence and change in concentration of specific molecules in an organism by labeling it on a specific ligand or probe. Some of the applications of Cyanine7 in molecular sensors are listed below:

1. pH sensors: Cyanine7 is labeled on a pH-sensitive ligand to measure changes in pH within an organism by changes in fluorescence intensity or fluorescence spectrum. For example, labeling Cyanine7 on a pH-sensitive dye is used to fluorescently image dynamic changes in intracellular pH.

2. Ion sensors: Cyanine7 is labeled on an ion-sensitive ligand to detect changes in the concentration of specific ions in an organism through changes in the fluorescence spectrum. For example, Cyanine7 is labeled on a calcium ion-sensitive ligand for fluorescence imaging of changes in the concentration of calcium ions in cells.

3. Oxygen sensors: Cyanine7 is labeled on oxygen-sensitive ligands to measure changes in oxygen concentration in organisms through changes in fluorescence intensity or fluorescence lifetime. For example, Cyanine7 is labeled on an oxygen-sensitive dye for fluorescent imaging of dynamic changes in intracellular oxygen concentration.

4. Molecular recognition sensors: Cyanine7 is labeled on specific molecular recognition ligands to detect the presence and concentration changes of specific molecules in an organism through changes in fluorescence spectra. For example, Cyanine7 is labeled on chemosensors for fluorescence imaging of the distribution and concentration changes of specific molecules.

In conclusion, Cyanine7 has a wide range of applications in molecular sensors and can be used in experiments such as pH sensors, ion sensors, oxygen sensors and molecular recognition sensors. By labeling Cyanine7 on specific ligands or probes, highly sensitive detection and quantitative analysis of specific molecules in organisms can be achieved. Due to the near-infrared fluorescence properties of Cyanine7, it can be used for molecular sensing in complex organismal environments, improving the sensitivity and selectivity of the sensors.
