Chemists Create a Sensor That May Detect the pH of Human Saliva

UrFU chemists have developed a sensor that can determine the pH level of human saliva. This is a fluorophore with a strong and steady emission that detects even minor pH changes in biological fluids (tenths). Micro doses of the chemical are used in the analysis, as well as a spectrometer in which the substance is irradiated with a specific light (its lifetime is tens of thousands of hours). In 5–7 seconds, the pH data emerges.

MIT Team Formulates a Photonic Method to Enhance Signals from Fluorescent Sensors

Fluorescent sensors are employed to label and image a broad range of molecules. They provide an exclusive look within living cells. However, they can primarily be employed only in cells grown in tissues close to the surface of the body or in a lab dish, as their signal is lost when they are embedded very deeply.
