Scientists have developed a new type of fluorescent probe that can be used to detect the microenvironmental changes in cells. The probe is made from a combination of two fluorescent molecules, which respond differently to changes in pH, calcium ion concentration, and temperature. This means that scientists can now simultaneously monitor multiple parameters in a single cell or tissue. The probe can be used for a variety of applications, including imaging single-cell physiology, drug testing, and tissue engineering. This breakthrough could open up new possibilities for understanding and manipulating the microenvironment of cells.
