Force-Detected Magnetic Resonance Imaging of Influenza Viruses in the Overcoupled Sensor Regime
Force-Detected Magnetic Resonance Imaging of Influenza Viruses in the Overcoupled Sensor Regime
Ultrasensitive nanomechanical sensors are envisioned to enable nanoscale magnetic resonance imaging (nano-MRI) and other scanning force microscopy applications. However, their sensitivity to very small forces makes such sensors susceptible to unwanted tip-surface interactions that cause bending and instability. This study shows how these noncontact interactions affect scanning force measurements. The …
