Background:

Precise control over the cellular microenvironment is crucial for understanding cellular and molecular processes.
Existing techniques may lack the resolution or biocompatibility needed for detailed cell studies.

Purpose of the Study:

To develop a novel plasma lithography technique for manipulating the cell microenvironment with micro- and nanoscale resolution.
To create patterned surfaces that guide cell attachment, movement, and interactions in a controlled manner.

Main Methods:

Utilized low-temperature plasma and a physical mold to selectively modify surface chemistry on polymeric substrates.
Achieved feature sizes ranging from 100 nm to millimeters, creating stable, biocompatible chemical patterns.
Applied the technique to form diverse cell networks for studying migration, signaling, and tissue formation.

Main Results:

Developed a plasma lithography method for creating patterned surfaces that guide cell behavior.
Demonstrated stable, biocompatible surface patterns on transparent polymeric substrates lasting weeks to months.
Enabled discrete, clear observations of single to multicell processes like migration and adhesion.

Conclusions:

The plasma lithography technique offers a powerful tool for controlled manipulation of the cellular microenvironment.
This method facilitates long-term studies of cellular processes and interactions in a biologically relevant context.
The technique is versatile, biocompatible, and suitable for various biological applications and investigations.
