Quantum Nanosensors Measure Temperature Variations Inside Living Cancer Cells
Researchers have developed molecular quantum nanosensors capable of measuring temperature variations within individual living cancer cells, including specific regions like the nucleus. Published in Science Advances, this study addresses limitations of previous nanodiamond-based thermometers by utilizing pentacene molecules embedded in polymer-coated crystals. These sensors, ranging from 200 to 500 nanometers, exploit quantum superpositions of electron states. When exposed to green lasers and specific microwave frequencies, the sensors' red glow dims in a manner directly correlated to ambient temperature. This technology allows for precise thermal mapping, revealing that different parts of a cell can vary in temperature by up to 1 degree Celsius. The breakthrough offers new possibilities for studying cellular metabolism and chemical reactions at the smallest scales, providing a more consistent and accurate tool than prior methods. The research team successfully introduced these sensors into cancer cells via absorption or direct injection, demonstrating their potential for advanced biological analysis and medical research applications.
