Combining monodisperse drop generation with inertial ordering of cells and particles, we describe a method to encapsulate a desired number of cells or particles in a single drop at kHz rates. We demonstrate efficiencies twice exceeding those of unordered encapsulation for single- and double-particle drops.

This video describes the non-enzymatic dissociation of fresh human tissue to obtain viable cells. The technique is used for qualitative and quantitative analysis of CD45 positive cells (lymphocytes/leukocytes) present in various normal and malignant human tissues.
FAQs
Stiffness, deformability, adhesion, and force generation provide complementary mechanical readouts rather than a single cancer marker. Measuring several properties can show how an individual cell interacts with its surroundings and whether its physical behavior differs from that of healthy cells. This multidimensional view supports characterization of disease-related cellular change.
Mechanical behavior reflects the combined contribution of the plasma membrane, cytoskeleton, nucleus, and extracellular environment. Because these elements interact, a measured change in stiffness or deformation should be interpreted as a property of the cellular system, not automatically assigned to one structure. This perspective helps connect physical measurements with cell function.
Applying a controlled force and observing the resulting deformation links an experimental input to a measurable cellular response. The relationship can be used to assess properties such as stiffness and deformability, while force generation and adhesion provide additional dimensions of behavior. Together, these readouts help describe how individual cells function or change.
Single Cell Mechanics is especially informative when cancer research needs to distinguish malignant cells from healthy cells at the individual-cell level. Physical differences can complement other observations by supplying evidence about how cells behave mechanically. The same measurements can also characterize cellular changes associated with disease, rather than limiting analysis to one property.
An assay begins by selecting a mechanical property, applying a controlled force or tracking cell deformation, and recording the resulting response. Atomic force microscopy, optical tweezers, and microfluidic assays are among the approaches identified for this purpose. The selected setup determines which aspect of single-cell behavior becomes measurable.
The overview identifies atomic force microscopy, optical tweezers, and microfluidic assays as methods for measuring single-cell mechanics. It does not specify that one universally outperforms the others. Researchers should therefore relate method selection to the intended measurement, whether stiffness, deformability, adhesion, force generation, or deformation under controlled force.
In cancer research, measurements from individual cells can be used to distinguish malignant from healthy cells, characterize invasion and metastasis, and assess responses to treatment. They may also help identify mechanical features relevant to diagnostic and therapeutic strategies. Thus, the approach connects cell-level physical behavior with important cancer questions without reducing analysis to one property.
