From ancient frescoes to bronze artefacts, our cultural heritage is fragile — and time is relentless.

Now, science is offering tools small enough to protect history at the nanoscale. Be it ancient frescoes to historic sculptures, our shared heritage faces constant threats — pollution, humidity, corrosion, and time itself. Today, advanced nanotechnologies are redefining how we protect the materials that define human history.

Through nanoscale innovation, it’s now possible to reinforce fragile surfaces from within, create invisible protective layers that shield against environmental damage, and monitor changes in real time. These ultra-fine treatments work seamlessly with stone, metal, wood, textiles, and paper — enhancing durability while preserving authenticity.

Solutions for Archaeological preservation have never been this advanced.

SMARTER PROTECTION STRATEGIES

Every artefact tells a story — but time, corrosion, microbes, and environmental stress threaten to erase it. Quantum materials (< 20nm size) deliver next-generation conservation: invisible, non-invasive, and ultra-effective, outperforming conventional nanoparticles in every way.

CRUCIAL ASPECTS OF PARTICLE SIZS

Most commercial nanoparticles are too large (>40 nm) to protect delicate artefacts effectively. They behave like microparticles, requiring high doses to achieve limited results, while clogging surfaces, aggregating, and failing to reach fine pores.

Quantum materials under 20 nm are ultra-efficient in protection at minimal doses — preserving both structure and appearance. Quantum materials (<20 nm) :

• Penetrate deep into micro- and nano-porous networks

• Provide precise reinforcement at ultra-low doses

• Deliver superior performance without altering appearance or structure

QUANTUM MATERIALS  - KEY BENEFITS

Preserving history requires materials that work at the smallest scales without compromising the original artefact. Here’s why sub-20 nm quantum particles are redefine restoration:

1. Superior Penetration and Surface Interaction
Particles smaller than 20 nm navigate micro- and nano-porous networks of limestone, fresco plaster, or corroded metal without clogging pores or forming visible films. 

The result: deep consolidation while preserving optical and textural integrity.

2. High Surface Area and Quantum Reactivity
Quantum confinement boosts surface energy and reactivity per unit mass, enabling transformations such as mineral re-precipitation, oxide stabilization, or photocatalytic cleaning at ultra-low doses.

→ Effective restoration with almost no change in color or bulk composition.

3. Controlled Kinetics and Selective Interaction
Engineered charge states, ligand coatings, and hydrophilic/hydrophobic balance allow selective interaction with deterioration compounds (sulfates, nitrates, chlorides) while leaving the original mineral matrix intact.

4. Reduced Optical Disturbance
Particles smaller than ~20 nm are optically transparent, preserving the authentic appearance of painted surfaces, glazes, and patinas.

5. Long-Term Stability and Reversibility
Nanostructured consolidants mimic the crystal chemistry of original materials, ensuring compatibility, reversibility, and non-invasiveness — the pillars of ethical conservation.

SUMMARY

NANOARC’s quantum materials are engineered for deep penetration, molecular precision, and optical transparency. 

By controlling particle size, surface area, and chemical reactivity, our materials strengthen artefacts from within, ensuring authenticity, reversibility, and long-term preservation with solutions that span but are not restricted to :

• Invisible, non-invasive coatings: Preserve colour, texture, and breathability of stone, metals, wood, paper, and textiles.

• Safe for light-sensitive artefacts: Protect murals, illuminated manuscripts, delicate pigments, and textiles without light exposure.

• All-condition antimicrobial protection: Effective in both light and dark, halting microbial growth.

• Adaptive and long-lasting: Respond to environmental changes for continuous protection.

• Low-dose efficiency: Maximum performance without surface alteration or aggregation.

WHY NANOARC ?

NANOARC remains the primary company designing, manufacturing, and supplying quantum materials at scale, ensuring long-term availability for major restoration projects.

Every artefact is unique. We design and manufacture custom nanomaterial treatments and application protocols for :

• Multi-material objects

• Fragile pigments

• Hybrid organic-inorganic substrates

By partnering with restoration service firms, NANOARC aims to bridge scientific innovation and cultural stewardship. Together, we can equip conservators with cutting-edge, sustainable tools to safeguard artworks, monuments, and artefacts — ensuring that the beauty of the past endures for generations to come.

For restoration professionals, NANOARC solutions offer more than protection; they offer peace of mind. Treatments that are designed to be non-invasive, reversible, and visually imperceptible, aligning with the strictest conservation principles.
