论文摘要
长而细的扫描力悬臂对小力量敏感，但也容易受到有害的非接触互动的影响。在这里，我们提出了一个实验，该实验是一个悬臂，其弹簧常数和静态偏转由尖端和表面之间的相互作用主导，我们称之为``过耦合''。相互作用是超敏测量的障碍，例如纳米级磁共振成像（Nanomri）。我们讨论了克服过度耦合所带来的挑战的几种策略，并证明了质子纳米里的质子纳米里颗粒颗粒的质子测量。
Long and thin scanning force cantilevers are sensitive to small forces, but also vulnerable to detrimental non-contact interactions. Here we present an experiment with a cantilever whose spring constant and static deflection are dominated by the interaction between the tip and the surface, a regime that we refer to as ``overcoupled''. The interactions are an obstacle for ultrasensitive measurements like nanoscale magnetic resonance imaging (nanoMRI). We discuss several strategies to overcome the challenges presented by the overcoupling, and demonstrate proton nanoMRI measurements of individual influenza virus particles.
