Z-Chitosan · antimicrobial materials technology
Protection that begins in the material.
Z-Chitosan combines chitosan with plant extracts into an antimicrobial system for medical devices, plastics, textiles and coatings. ZCP develops it with manufacturers, all the way to series production.

ZCP – Z-Chitosan Products Germany, based in Dresden, develops Z-Chitosan, an antimicrobial system of chitosan and plant extracts, and works with manufacturers to bring it into medical devices, plastics, textiles and coatings.
Principle
Three steps from raw material to surface.
What Z-Chitosan is, how it gets into the material and what the literature describes about its action at the cell.
-
01 · Structure
Chitosan meets plant extract
Chitosan, a cationic biopolymer derived from chitin, is combined with plant extracts in a multi-stage emulsion cross-linking process. Named in the patent, among others: thyme, oregano, cinnamon and clove.
What Z-Chitosan is -
02 · Incorporation
Four routes into the material
In the polymer as masterbatch, on the surface as a coating, on the fibre as a finish or in formulations. Suitability for your material is assessed case by case.
The four routes -
03 · Mode of action
Plus meets minus
The positively charged chitosan chain binds electrostatically to negatively charged components of the cell envelope. Binding can make the membrane more permeable. This is how the literature describes it.

Scale Journey
From catheter to molecule.
Six steps, six orders of magnitude. Pick a step or start the journey – the scale bar follows.
1 cm
The catheter tip
A silicone urinary catheter with two drainage eyes. This is where microorganisms either settle or do not.
What am I looking at?
The Scale Journey shows in six steps how small the place is where antimicrobial materials work: from the catheter tip (1 cm) to the silicone surface (1 mm), its topography (100 µm) and attaching bacteria (10 µm), down to the interface of coating and cell envelope (1 µm) and the chitosan chain (1 nm). The images are visualisations, not measurements.

Why
Why ZCP exists.
- Healthcare-associated infections in the EU/EEA
- 4.3million
- patients in the EU/EEA acquire at least one healthcare-associated infection every year (estimate).
- Literature ECDC, point prevalence survey 2022–2023, published 2024
- Deaths due to antimicrobial resistance
- 1.14million
- deaths worldwide in 2021 were directly attributable to bacterial antimicrobial resistance.
- Literature GBD 2021 Antimicrobial Resistance Collaborators, The Lancet 2024; 404: 1199–1226
