This workflow enables lamella production targeting fluorescently labeled biological structures that are small (<1 μm in axial extent) and rare (1 copy per cell) using a cryogenic tri-coincident imaging platform. This platform integrates fluorescence microscopy, focused ion beam milling, and scanning electron microscopy at a single focal position and enables simultaneous fluorescence microscopy while milling.

Here, we present a pipeline for 3D-correlative focused ion beam milling on guiding the preparation of cellular samples for cryo-electron tomography. The 3D position of fluorescently tagged proteins of interest is first determined by cryo-fluorescence microscopy, and then targeted for milling. The protocol is suitable for mammalian, yeast, and bacterial cells.
FAQs
Grinding media transfer mechanical energy to the sample through repeated impacts, friction, and shear. Rotating or oscillating motion determines how often these interactions occur and how strongly the material is stressed. Their combined action can break down solids, improve mixing, and produce a more uniform material for later analysis or formulation work.
These forces affect different aspects of mechanical processing. Impact contributes to repeated striking of the solid, while friction and shear promote rubbing, deformation, and mixing between particles and the milling media. The balance among them influences sample uniformity and the particle size ultimately obtained, making the motion of the jar important for experimental outcomes.
Dry and liquid-assisted conditions provide different processing environments for the sample. The appropriate choice depends on the material being treated and the desired particle size. Selecting between these conditions is therefore part of tailoring the milling process, particularly when preparing biological samples, chemical materials, drug formulations, or nanostructured compounds for cancer-related studies.
Researchers should match the milling conditions to the sample type and intended outcome. Important considerations include whether processing should occur dry or with liquid assistance, whether the goal is reduction, mixing, or mechanical processing, and what particle size or degree of uniformity is required. These choices determine how suitable the resulting material will be for downstream characterization.
In cancer research, milling jars can prepare homogenized biological samples and process chemical materials before analysis. More consistent processing improves sample uniformity, which can support downstream characterization. The resulting materials may help researchers examine biological or chemical features relevant to cancer studies without limiting the technique to a single experimental assay.
The approach supports work on drug formulations and nanostructured compounds, as well as investigations of therapeutic materials and their interactions with cancer-related systems. Milling can help create more uniform preparations for characterization, allowing researchers to evaluate material properties and study how processed therapeutic substances relate to cancer-focused experimental models.
