FleX AP: What is it?

FleX SN-AP (Silicon Nitride Antipathogenic Powder) is a silicon nitride powder that is being tested as an additive, coating, or composite to impart or enhance antipathogenic properties on different of applications.

This material powder composition shows antibacterial properties, antifungal properties, and antiviral properties1,2,3,21,51,52. The sintered silicon nitride powder particles reduce viral loads by as much as 99%, starting one minute58,59,60 after exposure. This result reflects specific chemical reactions on the surface of silicon nitride that resulted in RNA cleavage, protein disruption, and viral inactivation1.

WHAT MAKES IT DIFFERENT?

FleX SN-AP has been tested against viral strains that were each exposed to an experimental solution containing silicon nitride powders, using standard testing protocols.

  • Influenza A (Common Flu, H1N1)53,54
  • Feline calicivirus53,54
  • Enterococcus53,54
  • SARS-CoV-2 (COVID-19)1,2

The development of FleX SN-AP applications like masks, medical gowns, IT devices, air filters, and much more, aims to reduce and prevent the spread of viral diseases. FleX SN-AP can be used in a variety of composites for a multitude of applications. Contact SINTX to discuss your requirements at info@sintx.com

Silicon Nitride Applications

Masks

Given that SARS-CoV-2 (COVID-19) has been shown to remain active on mask filter materials for up to 7 days2,27, the prolonged use and reuse of masks and mask filters present a significant secondary exposure risk. SINTX’s FleX SN-AP material can help create a safe and effective consumer face mask with broad-spectrum antibacterial and antiviral activity 1,2.

Surgical Gowns, Drapes, and Curtains

From surgical drapes to gowns to antimicrobial bedsheets to medical tools, we are working with our partners to revolutionize their product lines with FleX SN-AP. This will help minimize the chance of healthcare-associated infections and stop the spread of disease 1,2.

Coatings

SINTX is working with partners to incorporate FleX SN-AP silicon nitride powder into polymer materials. These materials will help create safe and effective surfaces for IT devices such as cases for cell phones, tablets that are touched frequently, and high touch surfaces. SINTX aims to create surfaces that resist bacteria and viruses.

Filters

Now more than ever, we understand the importance of air quality and disease control. SINTX is working with partners to develop air filters that reduce the spread of pathogens. With FleX SN-AP, cabin filters for cars and public transit could not just filter dust and allergens, but also filter and inactivate bacteria and viruses.
Wound Care

Wound care

Antimicrobial wound dressings are used in the treatment of draining, exuding, infected and non-healing wounds where protection from bacterial contamination is desired. This can include both acute and chronic wounds including burns, surgical wounds, diabetic foot ulcers, pressure ulcers, and leg ulcers19. FleX SN-AP silicon nitride is inherently resistant to bacterial colonization and biofilm formation, making it antibacterial and an excellent material for consideration in a wound dressing19.
