Antimicrobial Activity and Characterization of a Validated Copper-Complexed Polymer Tape for Surface Disinfectant...

Area of Science:

• Materials Science
• Microbiology
• Infectious Disease Control

Background:

• Surface contamination in healthcare environments is a major factor in microorganism transmission.
• Antimicrobial coatings, particularly copper-polymer complexes, present a passive strategy to reduce environmental contamination and healthcare-associated infections.

Purpose of the Study:

• To evaluate the efficacy of a copper-alloy polymeric tape as an antimicrobial surface treatment.
• To assess its performance through physicochemical, in vitro, and hospital-based studies.

Main Methods:

• Characterization of the copper-alloy tape using XRD, Raman, SEM, and EDX.
• In vitro antimicrobial testing against Gram-positive and Gram-negative bacteria (ISO 22196:2011).
• A 19-week randomized clinical study in a hospital setting to quantify microbial loads on treated and control surfaces.

Main Results:

• Structural analysis confirmed copper's presence within the polymer matrix.
• Complete inhibition of bacterial growth was observed on the copper-alloy tape.
• Hospital surfaces treated with the tape showed significantly lower microbial loads over 19 weeks compared to controls.

Conclusions:

• The copper-alloy tape demonstrates robust antimicrobial properties.
• It serves as a sustainable intervention for reducing environmental contamination.
• This technology can effectively lower infection risks in healthcare settings.
