WebOct 26, 2024 · Materials that can cause a change in the optical properties of QDs can directly bind to an aptamer, where the aptamer can act as a linker bridging the QD and the material. As aptamers undergo changes in tertiary structure upon binding to analyte, the distance of QD and the material depends on an aptamer-analyte binding. WebWe present calculations of the optical force on heterodimer of two gold nanorods aligned head-to-tail, under plane wave illumination that is polarized along the dimer axis. It is found that near the dipole-quadrupole Fano resonance, the optical binding force between the nanorods reverses, indicating an attractive to repulsive transition.
