Multifunctional protective strategies for wooden cultural heritage: antimicrobial efficacy of polyacrylic resins, siloxane coupling agents, and silver nanoparticles.

ABSTRACT:

Introduction

This study evaluates two innovative protective treatments for wooden cultural heritage objects vulnerable to biodeterioration. The first involves polyacrylic resin solutions embedded with silver nanoparticles (AgNPs), while the second uses the siloxane-based coupling agent 3-mercaptopropyltrimethoxysilane (3-MPTMS) to enhance AgNP adhesion to wood surfaces.

Methods

Antimicrobial, anti-biofilm, and anti-metabolic activities were assessed using both qualitative and quantitative assays against biodeteriogenic strains (Penicillium chrysogenum, Bacillus cereus, and Bacillus megaterium). Additional analyses included extracellular nitric oxide (NO) production, phytotoxicity testing on Allium cepa, and correlations with biochemical parameters.
