• progression. This makes the cell stiffness a powerful biomarker for detecting cancer-related alterations in human bladder tumors. Conclusion Nanomechanical measurements performed with a force microscope at the single cell level have been applied to characterize the elastic properties of human bladder cancer

• capability, the sapphire substrate was patterned by using a grid of gold pillars as shown in Figure 1a. The center-to-center distance of the pillars is 5 μm and the pillar height 75 nm. Four pillars form a single cell, which can be repeatedly addressed in both an optical microscope and by AFM by simply

• and the highly magnetic MnFe2O4 nanoparticles, detection sensitivity for cell sensing was remarkably improved (Figure 7a) [15]. Notably, as shown in Figure 7b, the detection threshold was reduced to approximately single-cell level, far surpassing the sensitivity seen in either previous DMR experiments
