Summary We show a new atomic force microscopy technique for obtaining high‐resolution topographic images of large bio‐samples. To obtain high‐resolution topographic images for the samples, we fabricated a long polymeric tip with a small protrusion using two‐photon adsorbed photo‐polymerization techniques. The obtained tip length was over 50 µm, and the tip was used directly to visualize COS‐1 and 293 cells. Compared with commercial tips, the long tip made it easier to obtain topographic images of the large cells. In the magnified topographic images, the sub‐100‐nm resolution was confirmed with the long tips. This long probe tip is expected to broaden large sample‐related studies and applications in the future.
