Atomic force microscopy (AFM) combined with scanning electrochemical microscopy (SECM), namely, AFM-SECM, can be used to simultaneously acquire high-resolution topographical and electrochemical information on material surfaces at nanoscale. Such information is critical to understanding heterogeneous properties (e.g., reactivity, defects, and reaction sites) on local surfaces of nanomaterials, electrodes and biomaterials.

The lack of tools to measure material properties and tensional parameters in vivo prevents validating their roles during development. We employed atomic force microscopy (AFM) and nanoparticle-tracking to quantify mechanical features on the intact zebrafish embryo yolk cell during epiboly. These methods are reliable and widely applicable avoiding intrusive interventions.

FAQs
When the probe’s biological component interacts with a target, contact or binding generates a force on the cantilever. That force produces cantilever deflection, which a laser-based detection system measures. The resulting signal can be interpreted as force data describing the interaction or as topographic data describing the surface, linking molecular recognition to nanoscale measurement.
The biological component supplies selectivity that a mechanical sensor alone would not provide. By recognizing or interacting with biomolecules, cells, or other living materials, it helps the probe examine specific biological interfaces rather than only recording physical surface features. This combination supports measurements of engineered surfaces where biological identity and nanoscale mechanical response both matter.
Cantilever deflection provides the mechanical readout of the probe-target interaction. As the functionalized tip contacts or binds a target, the cantilever responds to the generated force, and laser detection converts that response into measurable information. This mechanism allows researchers to connect nanoscale biological interactions with quantitative force measurements and surface characterization.
A bio-hybrid AFM probe can provide force data and topographic data. Force measurements reveal responses associated with interactions between the functionalized tip and its target, while topographic measurements describe surface features at the nanoscale. Together, these outputs allow engineered interfaces to be examined both for their physical structure and for how they interact with biological materials.
The probe is prepared with a biological component at its tip, then positioned so the functionalized tip can contact or bind the target. During this interaction, the cantilever responds to generated forces. A laser-based detector records the deflection, and the resulting signal is used to obtain force or topographic information about the engineered surface or biological target.
Engineers use bio-hybrid AFM probes when a study requires both biological specificity and precise nanoscale force measurement. Applications described for these probes include biosensing, molecular recognition studies, surface characterization, and nanomechanical analysis. They also support diagnostic-device design, biointerface characterization, and development of biomimetic materials by revealing how engineered surfaces interact with biological systems.
