Resonance techniques are experimental methods that exploit the resonant interaction of oscillatory fields with matter to probe structural, electronic, or dynamic properties with high sensitivity and selectivity. They include nuclear magnetic resonance (NMR), electron paramagnetic resonance (EPR/ESR), magnetic resonance imaging (MRI), nuclear quadrupole resonance (NQR), and various optical and acoustic resonance-based methods. By tuning the frequency of an applied electromagnetic or mechanical field to match characteristic energy-level spacings or normal modes, these techniques enhance signal response, enabling precise measurements of local environments, molecular conformations, spin dynamics, and relaxation processes in physics, chemistry, biology, and materials science.
Researchers at Oregon State University have developed and tested in a mouse model a new type of nanoparticle that enables the removal of melanoma tumors with a low-power laser. After the systemically administered nanoparticles ...
