Area of Science:

• Nanotechnology
• Materials Science
• Biomimetics

Background:

• Natural cicada wings possess unique nanopillar structures.
• Existing nanofabrication methods often require cleanroom environments.

• To demonstrate simultaneous duplex imprinting of different materials.

Main Methods:

• Utilized natural cicada wings as stamps for nanoimprinting.
• Combined top-down and bottom-up nanofabrication approaches.
• Performed duplex imprinting on dicing tape with acrylic and UV optical adhesive.
• Investigated nanoparticle behavior on replicated surfaces.

Main Results:

• Achieved large-area nano-duplex imprinting using cicada wing stamps.
• Demonstrated successful replication on nonplanar surfaces.
• Observed promising nanoparticle self-assembly on replicated nanowell arrays.
• Measured changes in contact angle after oxygen plasma treatment.

Conclusions:

• The developed technique offers a scalable and efficient method for nanostructure fabrication.
• Cicada wing-based imprinting facilitates benchtop nanofabrication.
• The process holds potential for high-throughput commercial manufacturing of nanostructure elements.
• The replicated surfaces show potential for controlled nanoparticle self-assembly.
