Abstract
The key to enhance the imaging rate without damaging delicate biological samples in life science appli-cations is to design a cantilever probe with low spring constant but high resonance frequency. Achieving these two key mechanical characteristics is challenging due to their direct proportional relationship.Here, we report a silicon dioxide-based cantilever design that enabled low spring constant while ensur-ing high resonance frequency. In comparison to the existing cantilevers for HS-AFM for life science applications, this cantilever demonstrated the lowest spring constant with the highest resonance fre-quency to spring constant ratio and addressed the challenge.
