nanoDOVID® – Shaping Light into Security

Advanced Nanoengineered Optical Protection for the Modern World

In an era where counterfeiting techniques are becoming increasingly sophisticated, the demand for robust, future-proof security features has never been greater. nanoDOVID® represents a breakthrough in optical security technology, offering a fundamentally new approach to protecting identity documents, banknotes, and documents. Developed by IQ Structures, this advanced solution operates at the nanoscale, where light itself becomes the medium of security.

The Science Behind nanoDOVID®

At the heart of nanoDOVID® lies a highly advanced system of nanoengineered optical structures. These structures are not designed manually but are calculated using sophisticated mathematical algorithms and fabricated point-by-point with extreme precision.

Unlike conventional optical security features, nanoDOVID® does not rely on periodic patterns. Instead, it creates a complex aperiodic structure, where multiple optical effects are layered within a single area. This unique configuration results in a structure that is virtually impossible to replicate or reverse-engineer using current counterfeiting technologies.

The combination of algorithmic design and nanoscale fabrication ensures that every feature is both visually striking and inherently secure.

Freedom in Design

One of the defining advantages of nanoDOVID® is the unprecedented level of control over structural profiles. Designers can precisely manipulate how light interacts with the surface, enabling the seamless integration of multiple visual characteristics, including:

• Varying textures
• Controlled levels of mattness and glossiness
• Contrasts between dark and light areas

This flexibility allows for the creation of highly sophisticated designs with exceptional fidelity. The resulting features exhibit depth, plasticity, and dynamic behavior, including motion effects that become more pronounced when viewed from different angles.

Advanced Visual Features
nanoDOVID® enables a broad spectrum of optical effects that enhance both the security and visual appeal of IDs, banknotes, and secure documents. These effects are organized into five key categories based on their defining characteristics:

• Higher – Highly realistic 3D bas-reliefs with fine detail
• Deeper – Full-parallax 3D objects moving in space
• Hidden – Features visible only with a dedicated light tool
• Smaller – Nanographic and micrographic images
• Robotic – Machine- or smartphone-readable images

Each category represents a different dimension of visual and functional complexity, contributing to a multi-layered security concept.

Multi-Level Authentication

Security is only effective if it can be reliably verified. nanoDOVID® supports multi-level authentication, enabling different stakeholders to validate authenticity with ease:

• Overt features for instant visual inspection
• Covert features for trained personnel
• Forensic features for laboratory-level verification

In addition, the technology supports digital authentication via smartphones, bridging the physical and digital worlds and enhancing accessibility in real-world use cases.

Flexible Applications Across Security Documents

nanoDOVID® is designed for seamless integration into a wide range of security formats, including:

• Identity documents (full-face, patches, stripes and threads)
• Banknotes (stripes, patches and threads)
• Secure documents in various shapes and sizes.

This adaptability makes it suitable for both existing and next-generation security concepts.

A Complete Technology Platform

Beyond the optical feature itself, nanoDOVID® is powered by a comprehensive end-to-end technology platform from IQ Structures, built on unique proprietary expertise. This includes:

• Specialized software for precise template creation and data preparation
• Advanced 3D designing of realistic and dynamic visuals
• Nanoscale lithography translating digital designs into physical structures
• Controlled mass production ensuring consistency and scalability

This integrated approach guarantees that the final product maintains the highest standards of quality and security from concept to deployment.

Proven Excellence

nanoDOVID® is not only technologically advanced but also internationally recognized. IQ Structures has repeatedly received industry awards, including the recent 2025 IOTA Excellence in Optical Technologies Award for Best Origination.

The nanoDOVID® solution is also proven in the market and is used worldwide, reflecting its reliability and trust among leading institutions.

Conclusion

nanoDOVID® represents a paradigm shift in optical security. By combining mathematical precision, nanoscale engineering, and creative design freedom, it delivers a level of protection that is both visually compelling and extremely difficult to counterfeit.

True to its motto — Shaping light into security — nanoDOVID® transforms light into a sophisticated, dynamic, and highly reliable defense against forgery in an increasingly complex world.
