SmartPATTERN®
24 mm Dynamic Micropatterned Coverslips for Controlled Cell Migration
SmartPattern® dynamic micropatterned coverslips enable spatial and temporal control of cell adhesion and migration. Cells initially adhere to predefined regions on a 24 mm glass substrate, while surrounding areas remain non-adhesive.
At a selected time point, a bioorthogonal click chemistry reaction renders these surrounding regions adhesive, allowing cells to migrate beyond their initial boundaries.
This technology supports controlled cell migration assays, wound-closure studies and time-lapse imaging without mechanical disruption of the cell layer.
WHY USE SMARTPATTERN® DYNAMIC MICROPATTERNED COVERSLIPS?
Control Initial Cell Positioning
Confine cells to predefined adhesive geometries before initiating migration, providing controlled starting conditions for cell behavior studies.
Trigger Cell Migration on Demand
Use a bioorthogonal click chemistry reaction to make previously non-adhesive regions cell-adhesive at a selected experimental time point.
Compatible with High-Resolution Imaging
The glass substrate supports phase-contrast microscopy, immunofluorescence and time-lapse imaging to monitor cell spreading and migration.
Ready-to-Use Micropatterned Substrates
Prepatterned coverslips are supplied individually in 35 mm Petri dishes, avoiding the need for users to manufacture the micropatterns themselves.
HOW DOES DYNAMIC MICROPATTERNING WORK?
SmartPattern® dynamic micropatterning combines predefined cell-adhesive geometries with a chemically activatable, non-adhesive surface.
During initial culture, cells attach to the adhesive regions while the surrounding polymer coating restricts adhesion. Adding a DBCO-RGD triggering reagent initiates a bioorthogonal click chemistry reaction that functionalizes the surrounding regions with cell-adhesive ligands.
Cells can subsequently spread and migrate into these newly adhesive areas, enabling researchers to study migration from a defined starting geometry and activation time.
Principle of dynamic micropatterning: cells initially adhere to predefined geometries surrounded by non-adhesive regions. Addition of the DBCO-RGD triggering reagent renders the surrounding surface adhesive, enabling cell spreading and migration.

The 24 mm SmartPattern® dynamic micropatterned coverslip is organized into eight zones: seven zones with defined micropattern dimensions ranging from 10 to 100 µm, and one zone combining multiple pattern sizes. This layout allows researchers to investigate different cell geometries and pattern dimensions on a single substrate.
Standard arrangement of micropatterned areas on a 24 mm glass coverslip. Seven areas contain different pattern sizes, while the eighth combines multiple sizes.
APPLICATIONS OF DYNAMIC MICROPATTERNED COVERSLIPS
Wound-closure assays
Generate defined cell-free regions without mechanically scratching a cell monolayer, then initiate and monitor cell migration after chemical activation.
Collective cell migration
Study the spreading and migration of cell populations from predefined geometries, including circular islands and rectangular patterns.
Time-resolved cell spreading
Investigate how cells respond when previously non-adhesive substrate regions become available for attachment, using microscopy to track their spatial redistribution over time.
Application example: Mesenchymal stem cell migration
In an illustrative 4Dcell wound-closure experiment, mesenchymal stem cells were cultured on an 18 mm dynamic micropatterned coverslip containing a 500 µm-wide non-adhesive region.
Following activation with 50 µM triggering reagent, cell migration was monitored by image analysis. The activated condition reached 98.6% wound closure after 24 hours.
This example illustrates a specific experimental configuration rather than a general performance specification for the current 24 mm coverslip format.
STATIC VS DYNAMIC MICROPATTERNING
Static micropatterned coverslips provide predefined adhesive regions that constrain initial cell attachment and geometry throughout the experiment.
Dynamic micropatterned coverslips add temporal control: initially non-adhesive regions can be activated using click chemistry, allowing cells to spread and migrate beyond their original patterns.
Choose static micropatterns for cell shape control and spatial organization, or dynamic micropatterns when controlled initiation of cell migration is required.
