Abstract Bactericidal materials gained interest in the health care sector as they are capable of preventing material surfaces from microbial colonization and subsequent spread of infections. See all images 5 Free text.

Supplemental Content Full text links. Generate a file for use with external citation management software. AFM measurements of the PA6 control acompound 1 b and compound 3 c.

Surface roughness is depicted in a range from 0 to nm.

As it was found reliable for testing the biocidal activity of antimicrobially active materials and surface coatings most of the laboratories participating in this study used this protocol. However, commercialization of antimicrobial materials requires proof of their efficacy, which is usually done using in vitro methods.

Determination of the antibacterial effect of compound 1 and 3 on E. Fig 3 Assessment of the physiological state of the microorganisms 8201 the outcome of antibacterial testing of compound 1 and 3.

Note that the R values were calculated to the growth controls at the respective time points to avoid bias.

In conclusion, to enable assessment of the results obtained it is necessary to evaluate these single parameters in the test protocol carefully. Please review our privacy policy. National Center for Biotechnology InformationU.

The first round of testing showed that analyses in the different laboratories yielded different results, especially for materials with intermediate antibacterial effects distinctly different efficacies were noted. Therefore, a round robin test for evaluating antimicrobially active biomaterials had to be established.

Bactericidal materials gained interest in the health care sector as they are capable of preventing material surfaces from microbial colonization and subsequent spread of infections.

Experiments were performed in nutrient broth diluted 1:
