Research + Results

Data Generated by Third-Parties

AIONX® is producing disposable covers incorporating the AIONX® technology for hospital bed rails and other high touch surfaces in hospital rooms. Third party researchers have conducted a variety of studies involving the AIONX® technology generally and the AIONX® bed rail covers in particular. The AIONX® technology is registered with the EPA (EPA Reg. No. 91681-1) as an antimicrobial agent that effectively inhibits the growth of bacteria, fungi, algae, mold, and mildew that cause unpleasant odors, discoloration, staining, deterioration or corrosion on surfaces to which it is applied, including hospital surfaces. The EPA has not reviewed or approved, nor does AIONX® make, any claims that its technology has efficacy against any particular pathogenic microbes.

Intensive Care Unit Clinical Study

A clinical trial in a tertiary care hospital demonstrated a consistent 90% decrease of opportunistic pathogenic bacteria by using an AIONX® bed rail cover (p-value < 0.008). Notable pathogens reduced included Enterococcus faecalis, Enterococcus faecium, Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus pneumoniae, and Pseudomonas spp. A 51% reduction of bacterial species was also recorded.  The full study methodology and results can be discovered through the sited material below.

Acute Toxicity Study on Mammalian Cell Types

Researchers at North Carolina State University assessed acute toxicity of the AIONX® technology on three mammalian cell types: neonatal human epidermal keratinocytes (HEK), neonatal human dermal fibroblasts (HDF), and normal human osteoblasts (OST).  They found that the AIONX® technology displayed good biocompatibility.

Nursing Home Clinical Study

An efficacy study led by Penn State University researchers in nursing home cohort demonstrated 86.74% average reduction of bacterial contamination by AIONX®bed rail covers over a nearly 3 week period. The eradication of 8 bacterial species was also observed, among them strains of Staphylococcus aureus and Staphylococcus cohnii.

In Vitro Virus Study

Researchers at Utah State University assessed the antiviral capabilities of the AIONX® technology. Log 3 (99.9%) reduction of viability was observed of both murine norovirus CW1 and H1N1 influenza virus.

In Vivo Animal Study

Penn State University researchers conducted preliminary rat studies to identify the effectiveness of using the AIONX®technology on indwelling residual hardware devices. The researchers observed a large, statistically significant reduction of infections when the AIONX® technology was present.

In Vitro Bacteria Study

Researchers at Penn State University led a study to assess the ability of the AIONX®  technology to effect gram positive and gram negative bacteria, as well as antibiotic-resistant bacterial strains, known to frequently contaminate hospital environments. Consistent log 7 reduction at 20 minutes and log 2 reduction at 5 minutes was observed of a known strain of Escherichia coli and Methicillin resistant Staphylococcus aureus (MRSA).

Animal-Based Toxicity Studies and Physical-Chemical Analyses

An independent, third-party lab performed the following EPA-mandated studies of the silver and copper ink used in the AIONX® technology: an assessment of accelerated storage stability and corrosion characteristics; a thorough chemical analysis of the materials; an atomic absorption spectrophotometer analysis of the active ingredients; an assessment of the material’s flammability, pH, viscosity, density/relative density, and explodability; a dermal sensitization test in guinea pigs; an acute oral toxicity test in rats; an acute dermal toxicity test in rats; a primary eye irritation test in rabbits; and a primary skin irritation test in rabbits. The EPA registered the AIONX® technology after reviewing the foregoing data.
