See how Goldshield-related research connects laboratory and real-world evidence. Six peer-reviewed studies are presented with headline context and direct DOI links.
NASA JPL and Montana State University researchers evaluated antimicrobial and antifouling coatings on materials relevant to International Space Station water systems, including space-flown Pseudomonas aeruginosa PA14.
A real-world ICU study compared treated high-touch hard surfaces with placebo rooms under the same routine cleaning protocol, showing sustained microbial-load reduction in the treated group.
Henry Ford Hospital and Eastern Michigan University evaluated treated patient-gown fabric, Formica and stainless steel against clinical isolates including MRSA, Pseudomonas aeruginosa and Escherichia coli.
The study evaluated treated surgical-mask layers under bacterial aerosol exposure and examined whether coating affected whole-mask filtration performance.
Oak Ridge National Laboratory evaluated Goldshield 75 coating on polypropylene, charged polypropylene and commercial 3M filter media, including particle, bacterial and viral filtration performance.
The publication developed and applied a standardized method to evaluate residual viral activity on treated cotton textiles using HCoV-229E and cell-culture infectivity methods.
Review selected Goldshield-related study figures together with the testing setting, key outcomes and publication source, making it easier to understand what was tested, on which surfaces and against which microorganisms.
A single-arm prospective observational study covered 18 patient rooms, 6 high-touch locations per room and 18 patient turnovers per room. Goldshield 75 was applied after standard cleaning. The study used repeated-measures negative binomial regression to analyze CFU/100 cm² changes for total bacteria, Gram-negative bacteria and Staphylococcus aureus, with quantitative microbial risk assessment.
This follows real patient-room use over multiple turnovers, not only the moment immediately after cleaning.

An in-vitro study evaluated Goldshield 5 on cleaned materials and environmental surfaces using clinical isolates of MRSA, Pseudomonas aeruginosa and Escherichia coli. Treated patient-gown fabric, Formica and stainless steel were compared across time points.
The study is useful because it looks beyond hard surfaces and includes fabric, where microbes can behave differently.

A peer-reviewed study covalently attached Goldshield 75 to polypropylene, charged polypropylene and commercial 3M filter media by spray application, then assessed particle, bacterial and viral filtration as well as residual antimicrobial performance against Micrococcus luteus and Escherichia coli.
This study connects two practical questions: can the filter still filter well, and can the coated media suppress microbes captured on it?

A paper from Montana State University Center for Biofilm Engineering and NASA Jet Propulsion Laboratory compared antimicrobial and antifouling coatings for reducing biofilm on International Space Station water-system-related materials, including space-flown Pseudomonas aeruginosa PA14.
Biofilm is the protective layer microbes form on surfaces; controlling it is especially important in closed water-system environments.
