Controlled Cell Adhesion With ibidi Micropatterning
The ibidi µ-Patterning technology enables spatially defined cell adhesion for various 2D and 3D cell culture applications.
Miniaturized adhesive patterns (e.g., lines, squares, or dots) are irreversibly printed on the non-adhesive Bioinert surface of the ibidi Polymer Coverslip, allowing for precisely controlled cell adhesion. The µ-Patterns are dry-stable, sterile, and ready to use.
- Long-term stable, and biologically inert surface
- Superior to the standard ultra-low attachment (ULA) surfaces: no cell or protein adhesion (full passivation)
- Layered onto the ibidi Polymer Coverslip—the highest optical quality for imaging

The size of the µ-Pattern can be adapted to the morphology of the cell type of interest, so that an array of single cells can be conveniently analyzed using applications such as high-resolution imaging.

By using different geometries and sizes of the µ-Patterning, multi-cell arrays can be performed with defined adhesion for various applications, such as high-resolution imaging.

Defined adhesion spots, surrounded by Bioinert, are able to catch all adherent single cells from a cell suspension. Bioinert is fully non-cell-attachable. This forces all cells to aggregate to each other at the adhesion spots, thus forming spheroids in a defined and controllable way.

The size and the cell adhesion properties of the µ-Patterning can be adjusted to hold 3D spheroids and microtissues in position. Using this setup, cells in 3D can be studied during proliferation, differentiation, invasion, and migration.

µ-Patterning can also be used for neuronal stem cell culture, axonal isolation and outgrowth, and neurite polarization.
