Conclusion

Because of the growing demand for healthy living there is an increasing interest in materials capable of killing harmful microorganisms. Potential fields of application include, for example, water treatment, food processing and inclusion in medical devices. In the past mostly low molecular weight biocides were used. Such agents act efficiently by affecting cell metabolism but may be disadvantageous with respect to human toxicity and the formation of bacterial resistance. In many cases it is possible to minimize this disadvantages through the substitution of low molecular weight substances by macromolecular antimicrobial agents. Polycationic substances are well established nowadays1,2,3. We herein present the preparation and investigation of antimicrobial surfaces based on new functional ROMP polymers.
