EVŌQ MedTech is a development-stage nanotech innovator bringing a breakthrough antimicrobial platform to the medical device industry.
By incorporating antimicrobial protection into the material manufacturing process, our technology enables the next generation of medical devices to be intrinsically equipped with safeguards against pathogenic microorganisms like bacteria and fungi.


We have developed the first and only non-ionic silver nanoparticle, EVQ-218. Extensive lab studies demonstrate that EVQ-218 delivers high antimicrobial efficacy without ionic emissions, opening possibilities for widespread therapeutic use.1,2


The antimicrobial efficacy of EVQ-218 is rooted in its ability to disrupt bacteria’s metabolic processes.

  • By sequestering sulfur, EVQ-218 stops bacterial growth without compromising cell structures.
  • This disruption process leads to cell death without initiating drug resistance.
  • In contrast, ionic silver nanoparticles initiate drug resistance when rupturing cell walls.

Antimicrobial Platform Boasts Several Distinct Attributes:

  • Uniform Sub-10nm: Enables effective cell interaction and offers a high surface-area-to-volume ratio with repeatable results.
  • Non-Ionic: Efficacy without the risks and limitations linked to ion emissions.
  • Non-Oxidative: Mitigates need for added stabilizers and surface coatings.
  • Non-Toxic/Environmentally Friendly: No toxic byproducts created in the manufacturing process.

Validated lab testing of catheters, luers, and fittings manufactured with our proprietary antimicrobial nanoparticles extruded throughout the polymer demonstrated:

  • Strong antifungal and antibiofilm efficacy.
    • 4+ log reduction
  • Broad spectrum activity against all bacterial strains tested.
    • 64 strains
  • No degradation of antimicrobial activity; sustained presence for the life of the product.


Our antimicrobial nanoplatform is well positioned to target the 1 million+ Healthcare-Associated Infections (HAIs) that occur across the U.S. health care system annually, estimated to cost billions of dollars per year. 3

Bloodstream, pulmonary and urinary tract infections are a significant cause of morbidity and increased mortality in health systems across the U.S. and globally.4 In the U.S. alone, there are 250,000 central line associated bloodstream infections (CLABSI) every year5 from central-venous (CVC), subclavian (SC), internal jugular (IJ) and femoral (FEM) catheters.6

One million catheter-associated urinary tract infections (CAUTI) occur annually in the U.S. and 24-33% are drug resistant.7 Standard practice for hospitals and health systems is to remove/replace catheters at 15 days because data shows that nearly 100% of patients with catheters for more than 28 days will develop dangerous infections and are at risk for sepsis.

Current antibacterial coated catheters lose efficacy once inserted into patients, due to natural sloughing of the material, coupled with the short life of silver ion emission hindering the antimicrobial activity of the coatings. By embedding EVŌQ MedTech’s nanoparticles directly into the catheter, leading manufacturers aim to harness the precision and potency of our multi-patented platform to combat drug-resistant bacteria and significantly reduce HAI incidence.
