| תקציר≠ | Electron Paramagnetic Resonance (EPR), also called Electron Spin Resonance (ESR), is a spectroscopic technique that detects and characterizes unpaired electrons in molecules and materials. Discovered by Zavoiskii in 1945, EPR measures the absorption of microwave radiation by paramagnetic species in a magnetic field, providing information about electron spin states, local electronic environment, and molecular dynamics. | Surface Plasmon Resonance (SPR) is a real-time, label-free technique for detecting and monitoring biomolecular interactions at a sensor surface by measuring changes in the refractive index caused by ligand binding. Developed by Kretschmann in 1971 and applied to biosensing by Liedberg, Nylander, and Lundström in 1983, SPR is now a gold standard for measuring binding kinetics (association and dissociation rates) and equilibrium binding constants in protein interactions, antibody-antigen recognition, and drug discovery. |
