A novel soft-printing method enables the precise deposition of gold nano-islands (AuNIs) onto flexible synthetic and bio-polymer films. This patented structure delivers tunable optical effects across UV-NIR, enabling gentle focused photothermal warming and light-scattering/brightening to visibly smooth skin appearance, along with optional antimicrobial surface benefits. The patch conforms like an adhesive strip, remains breathable, and can be engineered for clear or tinted finishes.
Scalable soft-printing makes it compatible with common cosmetic substrates, bringing salon-grade, light-active performance to everyday beauty care.
Cosmetic applications - illuminating masks, under-eye brighteners, blemish covers, and smart patches that visually signal treatment time or exposure.
Medical applications - Antimicrobial surfaces and targeted thermal treatment.
- Customizable plasmonic properties while maintaining high transparency
- Cost-effective fabrication
- Biocompatible
- Compatible with a variety of substrates, including silk protein-based films
Soft-printing tape lithography has been successfully used to deposit plasmonic nanostructures on flexible polymer films, demonstrating tunable plasmonic properties with proof-of-concept results in silk protein-based films.
