Background:

Protein patterning is crucial for developing advanced proteomic tools, nanostructures, drug delivery systems, and biosensors.
Micro and nanoscale protein patterning aids in understanding protein function and interactions with biomolecules and cells.
Existing protein patterning methods often involve complex chemistries or are protein-specific, limiting their versatility.

Purpose of the Study:

To develop a versatile and accessible method for microscale protein patterning.
To utilize neutravidin for creating robust protein patterns on surfaces.
To demonstrate the functionality and stability of the patterned proteins.

Main Methods:

Development of a lithography-based approach combined with photoresist lift-off.
Utilizing neutravidin as a versatile linker for biotinylated molecules.
Surface characterization and functional validation through binding assays.

Main Results:

Successful patterning of biotinylated molecules at micron-scale resolution using the developed method.
Demonstrated functionality of patterned neutravidin through the binding of biotinylated beads and antibodies.
Enhanced stability of protein layers on glass surfaces due to improved physisorption after acetone lift-off, reducing the need for chemical immobilization.

Conclusions:

The developed neutravidin-based lithography and lift-off technique offers a versatile platform for microscale protein patterning.
This method overcomes limitations of existing techniques, enabling patterning of various biotinylated moieties.
The enhanced stability of protein layers suggests potential for robust biosensor and biomaterial applications.
