Antimicrobial.
Bioactive.
Pain-free.
NASK NANO is not just an antibacterial dressing -> Promote Hemostasis, Promote Respiration of Cells, Block and Kill Bacteria, Reduce Pain During Dressing Change.
Three problems conventional dressings can't solve.
Painful Dressing Changes
Gauze forms a solid compound after absorbing blood, adhering to the wound. Removal causes secondary bleeding and infection. Painful Dressing Changes
Continuous Infection Risk
Within hours of injury: 29 aerobic + 16 anaerobic bacterial species detectable. Positivity remains 66.7–75% post-debridement.
Antibiotic Limits
Most antibiotics target bacteria in reproductive phase. Biofilm bacteria are dramatically more resistant than free-floating cells.
Applying antimicrobial NASK Nano dressings first and then bioactive NASK Nano dressings is most beneficial for wound healing
Inflammation
Debris and pathogens dominate. Antimicrobial dressing establishes broad-spectrum, long-lasting bactericidal control.
Cell Proliferation
Fibroblasts proliferate. Bioactive dressing releases growth factors to accelerate cell proliferation.
Tissue Remodeling
Epidermis and dermis rebuild. Reduced scar formation via controlled moisture and growth factor delivery.
Pain relieve mechanism of NASK NANO
Nanofiber Dressing -> SUPER-LOW Adhesion Force -> Easy to remove
Pain-free removal of dressing is possible!
Step 1
Partial attachment via micro-air pockets
Step 2
Clot contracts, pulls fibers inward
Step 3
Dressing lifts clean — no secondary bleeding
Continuous Bacterial Killing Mechanism of NASK NANO
NASK’s nanofibers carry positive charges; bacterial surfaces are negative. Electrostatic attraction alters membrane permeability and osmotic pressure — contents outflow, microorganism dies on contact. No reproduction phase required.
Why the structure alone heals faster.
Promote Hemostasis, Promote Respiration of Cells, Block and Kill Bacteria by Nanofibers.
1000× finer than cotton gauze.
Cotton gauze
~200,000 nm
NASK nanofiber

WVTR 40–140 g/m²/hr — the healing window.
Hydrocolloid
Over-hydration. Impaired respiration.
Gauze
Wound dries out. Adhesion. Painful removal.
NASK Nanofiber
Moist environment. Fastest wound healing.
NASK NANO is not just an antibacterial dressing -> Promotes wound healing
Protects wounds from bacterial infections
The small pore size is effective in protecting the wound from bacterial infections.
Promotes cellular respiration
The high porosity of nanofiber dressings is very good for cellular respiration, which prevents the wound from drying out. This action can maintain a suitable moist environment for rapid wound healing.
Avoid secondary bleeding
The controllable surface energy of the nanofibers can avoid excessive coagulation at the interface between the tissue and the dressing, and can also avoid secondary bleeding caused by removing the dressing, thereby promoting wound healing.
Promotes blood clotting
The small pore size and high specific surface area of nanofiber dressings promote blood clotting. This facilitation effect relies on the structure of the nanofiber dressing and does not rely on any clotting factors/drugs.
Long-lasting bacteria-killing effect
Nanofibers are positively charged, and the surface of bacteria is negatively charged, and the positive and negative charges change the permeability and osmotic pressure of the cell membrane after attraction, resulting in capacitor flow and contact death of microorganisms.
Include Bioactive Material into Nanofiber in wound dressing
12 μg EGF is required per 100 cm² of wound. Applying precise doses via spray is difficult. The new EGF nanofiber dressing replaces the EGF spray — convenient, precise, stable.
