Characterization of surface properties and polymer brush behavior.
Spatially controlled cell seeding and adhesion experiments at 37°C.
Temperature-induced cell detachment and harvesting at <32°C.

Main Results:

Successfully created micropatterned surfaces enabling precise spatial control of cell adhesion.
Demonstrated reversible cell adhesion and release by modulating surface temperature.
Achieved efficient harvesting of adhered cells without compromising viability.

Conclusions:

Micropatterned thermoresponsive polymer brush surfaces provide a versatile platform for advanced single cell studies.
This technology facilitates controlled cell culture and non-invasive cell retrieval.
The developed surfaces hold significant potential for applications in cell-based assays and tissue engineering.
