Enabling functional phenomics at 

single-cell resolution

Array and track thousands of cells as they interact with others and respond to their immediate surrounding.

A Cellular Universe In Thousands Of gel Beads

The immediate surrounding of cells matters in vivo.
So why shouldn’t it in vitro?

Quantifying biological parameters in a population of cells obscures critical insights into how microenvironment and neighboring cells influence function, especially in heterogeneous samples. Unlock those interactions by performing single-cell measurements but on a massively parallel platform.

CellCity is a unique microfluidics concept for the analysis of live cells that documents what thousands of cells in a defined arrangement and environment are doing at single-cell resolution. Control cell proximity to elucidate interactions. Track phenotype changes over time and space. Open new frontiers in cell-based biomedical research. That is the transformative power of CellCity.


  • CELL INTERACTION ANALYSIS. Co-position cells to study hundreds of interactions at a time.
  • FUNCTIONAL GENETICS. Link changing functional phenotypes to underlying genotypes.
  • IN-DEPTH POPULATION STUDIES. Reveal how cells function in a physiologically accurate context.

Simple workflow. Easy setup. Powerful research tool.
Cell encapsulation

Cell encapsulation:

Encapsulate individual, pairs or groups of cells in a gel bead that acts as a protective and diffusible microenvironment. Work with a range of cell sizes, from prokaryotes to eukaryotes.

Gel bead trapping

Gel bead trapping:

Immobilize up to 2000 cell-laden gel beads in microfluidic traps on the CellCity Array Chip to form an array where each gel bead is uniquely identified by its precisely defined position.

Cell culture

Cell culture:

Culture and optionally stimulate cells under tightly controlled conditions. The cells can be uniformly perfused with nutrients or treatment factors across the CellCity Array Chip.

Cell analysis & Staining

Cell analysis:

Couple endpoint measurements to time-lapse data. Simultaneously capture the responses of single cells  in multiparametric analyses, such as time-lapse fluorescent imaging and immunohistochemistry.

Control unit

The CellCity Control Unit automates all workflow steps essential for reliable cell culture and analysis and executes the experimental design through integrated control software.

  • Powerful and fast, traps thousands of cell-laden gel beads on a CellCity Array Chip within a few minutes
  • Light-weight, easily portable and designed for a quick plug-and-play setup
  • Brings microfluidic cell culture to any lab (intuitive user experience, automated flow control and priming, bubble-free operation)
  • Precision engineering delivers uniform perfusion to ensure homogeneous culture conditions


On your inverted imaging system

The CellCity Incubator holds the CellCity Array Chip and maintains the relevant experimental conditions for long-term, live-cell analysis.

  • A complete, miniature incubator (37°C, 5% CO2). No need for any other chamber.
  • Designed in a microtiter plate format to fit on your inverted microscope setup.
  • Controlled and optimized heating to work with low volumes and temperature sensitive samples
  • The CellCity Incubator can be easily moved to a cell culture hood for uninterrupted sterile conditions and handling

The chip

with 2000 beads

The CellCity Array Chip is a high-precision microfluidic device that places single, pairs and groups of cells into an array of gel beads for sterile culture and analysis. No microfluidics experience required


  • Cell-laden gel beads are captured in the 500 microfluidic traps of 4 microfluidic channels to analyze up to 2000 gel beads at a time
  • Accommodates different cell types and cell lines, in particular primary cells (e.g. HUVEC, breast cancer cells, brain tumors, CAR-T cells, macrophages, leukemia cells and even bacteria)
  • Includes a high-resolution temperature sensor integrated at the cell culture site exactly where the correct temperature is needed
  • Augments insights with endpoint data by making it easy to stain cells (e.g., immunostaining, surface staining) after time-lapse (fluorescent) imaging


Ready-to-use Notebook included

User-friendly, proprietary PC-software communicates with the control unit to regulate and perform all essential workflow steps


  • Built-in performance-checks ensure reliable and accurate assay outcomes
  • Accelerates and simplifies workflows e.g. with cell counting and gel bead analysis tools

Using evorion CellCity, the research team examined cellular communication between individual primary endothelial cells (HUVECs) and breast cancer cells (MCF7).

They encapsulated single cells and co-positioned them on the CellCity Array Chip in a physiologically relevant microenvironment. Long-term live-cell imaging analysis at single-cell resolution revealed a previously unknown time-dependent uptake by cancer cells of extracellular vesicles derived from endothelial cells.

In addition, the cancer cells underwent significant morphological changes and expressed common endothelial markers, like VE-cadherin, after interacting with the endothelial cells.
