Absorbest BioShield is an innovative superabsorbent dressing for exuding wounds. It helps prevent biofilm formation on the dressing and in the immediate surrounding area.¹ Its mode of action is non-antimicrobial, meaning it does not kill bacteria.
1. Absorbs and retains wound exudate in the dressing
2. Traps bacteria in the wound exudate and retains them within the dressing
3. The contact surface makes it more difficult for microorganisms to attach and form biofilm

Absorbest BioShield is a sterile, conformable superabsorbent dressing for exuding wounds. Absorbest BioShield absorbs and retains exudate in the dressing. The exudate is absorbed vertically by the dressing and is retained in the core forming a gel, thus minimizing the risk of maceration and maintaining a a moist wound environment. The dressing remains dry and comfortable for the patient.
The dressing has a white wound contact layer that is placed towards the wound, helping to retain moisture and support a favourable wound-healing environment.²˒³˒⁴˒⁵
The wound contact layer can have a preventive effect on biofilm formation on the dressing surface and its immediate surroundings.¹ The biofilm-preventive function is based on a mechanism that does not release antimicrobial substances or kill the bacteria.
The dressing effectively manages wound exudate containing both bacteria and fungi.¹˒⁶ The white surface efficiently transports exudate away from the wound and distributes it evenly throughout the dressing’s DryMax Technology core.
The dressing has a green hydrophobic backing to reduce the risk of wound fluid strike-through. Its thin, soft, conformable design makes it suitable for all areas of the body. The seamless wound contact layer makes it easy to position over the wound. Absorbest BioShield is designed to work well with compression therapy.²˒³˒⁵

The wound-contact layer helps prevent biofilm formation on the dressing and in its immediate surroundings.¹
The biofilm-preventive effect relies on a non-antimicrobial mode of action that does not kill bacteria. Instead, the wound-contact surface makes it difficult for microorganisms to colonise the surface.¹
Choosing non-antimicrobial dressings when antimicrobial substances aren’t required supports antimicrobial stewardship (AMS) and contributes to the responsible use of antimicrobial treatments.¹³˒¹⁴˒¹⁵
The white surface efficiently draws away wound fluid containing both bacteria and fungi¹˒⁶ and distributes it evenly throughout the DryMax-technology dressing core.
The dressing has a green, hydrophobic backing that helps reduce the risk of wound fluid strike-through. Its thin, soft, conformable design suits all body areas, while the seamless wound-contact layer makes it easy to position over the wound. Absorbest BioShield is designed for use with compression therapy.²˒³˒⁵
After seven days, structured biofilm is present on both the uncoated control and DACC surfaces. In contrast, the Absorbest BioShield surface shows only scattered microbial cells, with no structured biofilm. The arrows highlight the key difference in organisation: biofilm forms dense, organised clusters of microorganisms.
In a preclinical porcine wound model, the Absorbest BioShield dressing had less biofilm accumulation on the surface, and the bacterial burden in wound tissue decreased more rapidly than with the control dressing.
Absorbest BioShield absorbs wound fluid and captures bacteria and fungi in the dressing core. Its technology helps prevent biofilm formation without using antimicrobial substances.
No. Absorbest BioShield contains no silver or other antimicrobial substances.
Yes. Absorbest BioShield is designed for use as a primary dressing, placed directly on the wound. For its biofilm-inhibiting surface to work optimally, position the white side against the wound bed. This helps the dressing manage exudate effectively and prevent biofilm formation where it is needed most.
The white side.
The white surface helps prevent biofilm from forming, while the dressing’s absorbent core removes exudate and bacteria.
Yes. Absorbest BioShield is designed to work well with compression therapy.
Absorbest BioShield is designed for exuding wounds, especially hard-to-heal wounds at risk of biofilm formation. Apply the dressing after cleansing and debridement, once the wound bed is prepared.
Absorbest BioShield is intended for exuding wounds.²,³ It is especially suitable for exuding, hard-to-heal wounds where biofilm formation is at risk. Examples include venous leg ulcers, arterial leg ulcers, and pressure ulcers.
Note! Do not use the dressing on the eyes, mucous membranes, or tendons, or in wound cavities, as it swells when it absorbs fluid.
No, change the dressing based on the wound’s clinical condition and before it becomes saturated. Absorbest BioShield requires less frequent dressing changes than conventional dressings.⁵
For biofilm inhibition, use Absorbest BioShield as the primary dressing, though it can also be used as a secondary dressing.⁴ If used as a secondary dressing, place the white side against the primary dressing. Tailor the dressing combination to the wound’s needs and local treatment practice.
Absorbest BioShield is designed to help prevent biofilm formation from the outset. Its unique contact surface makes it harder for microorganisms to attach and take hold, helping prevent biofilm formation.¹ This differs from other non-antimicrobial dressings, which bind microorganisms only after they come into contact with the dressing.¹¹
Like other non-antimicrobial dressings, it does not contribute to the increased spread of antimicrobial resistance.¹³,¹⁴,¹⁵
The wound-contact layer creates a surface that discourages microorganisms from adhering and establishing themselves. This helps prevent early biofilm formation without using antimicrobial agents to kill them. At the same time, the superabsorbent core absorbs wound fluid and traps bacteria and other substances within the dressing.¹,⁶
