The MoQNs mapped temperatures in cytoplasm and nuclei with 0.3C precision, detected paramagnetic radicals, and revealed localised temperature differences inside cancer-cell nuclei.
Published in Science Advances, the study said the pentacene-based sensors delivered threefold better spectral resolution than nanodiamonds and remained biocompatible across Hepa1-6, HEK 293H and HepG2 cells.
The team said the platform could help probe cancer-linked cell physiology and plans organelle-targeted delivery without microinjection, plus smaller sensors through surface engineering and controlled pentacene doping.
Beyond cancer, could these intracellular quantum spies help solve the mysteries of aging or Alzheimer's disease?
Can mapping a cancer cell's internal 'hot spots' guide new therapies that cook tumors from the inside out?
Absolute Temperature and Radical Activity Measured with Molecular Quantum Nanosensors in Living Cells
Overview
On April 29, 2026, researchers from Japan developed biocompatible molecular quantum nanosensors (MoQNs) that enable precise absolute temperature measurements and detection of radical-related signals inside living cancer cells with subcellular resolution. Unlike existing sensors, MoQNs achieve superior precision through molecular uniformity and maintain quantum functionality within cells, while their biocompatible design ensures no harm to cell health. Applying MoQNs revealed thermal hotspots and compartment-specific oxidative stress in cancer cells, offering new insights into tumor metabolism. Their versatility promises early detection of oxidative stress in other diseases, though challenges like scalable production and long-term safety remain before clinical use.
