Quantum Sensing of Free Radicals in Primary Human Dendritic Cells

Quantum Sensing of Free Radicals in Primary Human Dendritic Cells

ACS Nano (2021)

Utilizing quantum sensing with nitrogen-vacancy centers in diamonds to detect free radicals in human dendritic cells, overcoming traditional detection challenges. This innovative method highlights the significant variations in radical production among individuals and provides insights into the immune response mechanisms. The research successfully demonstrates real-time, localized measurements of radical levels, particularly focusing on the NADPH oxidase (NOX2) activity in cells. This technique not only offers a deeper understanding of immune system functioning but also holds potential for broader applications in biological research, including fertility treatments and the study of male infertility.
