Gel-Based Non-Destructive Antimicrobial Cleaning System for Stained Surfaces

Overview

This research initiative focuses on developing gel-based antimicrobial cleaning procedures as a non-destructive method for treating stained surfaces. The approach addresses a critical need in conservation and restoration, where traditional cleaning methods can damage delicate painted or finished surfaces. By formulating hybrid gels combined with enzymes and nanomaterials, the project aims to create cleaning agents that effectively remove stains while preserving surface integrity.

The solution is designed for applications where surface safety is paramount, including art restoration, heritage conservation, and the cleaning of sensitive coated materials. The research systematically evaluates gel formulations to identify compositions that deliver antimicrobial efficacy without compromising the underlying surface.

Technical specifications

Core technology and approach:

• Gel matrix design: Hybrid gels are formulated using polymers such as PVA-borax, gellan gum, and agar, exploiting the unique properties of gels that behave as solids yet retain liquid-like diffusion characteristics
• Functional additives: Enzymes and nanomaterials are incorporated into gel matrices to provide antimicrobial activity and enhanced cleaning performance
• Mechanical property optimization: Structural and mechanical properties of each gel formulation are characterized and tuned by adjusting polymer concentration and molecular weight
• Surface compatibility testing: Formulations are evaluated for safety on painted surfaces, ensuring non-destructive cleaning behavior

Key features:

• Non-destructive cleaning suitable for delicate or painted surfaces
• Dual-action capability combining stain removal with antimicrobial treatment
• Customizable gel compositions allowing tailored solutions for different surface and contamination types

Technology readiness level

The project is currently at an early-to-mid stage of laboratory development. Planned validation activities include preparing multiple gel types, synthesizing gel formulations loaded with nanoparticles and enzymes, creating stained test samples, characterizing the gels, applying them to stained surfaces, and evaluating antimicrobial effectiveness. The technology has not yet been validated in real-world restoration settings and requires further development before commercial deployment.
