| 摘要 |
The invention relates to soiling having a marker, characterized in that the soiling contains a marker, which is a natural or synthetic nucleic acid, DNA, RNA, or Spiegelmer or an analog and is applied to surfaces, wherein the marker is used at least to demonstrate the depletion of soiling having a marker after cleaning in order to enable at least one evaluation of the cleaning success or of spreading or of decontamination or of substance release. The production of a soiling surface is used in particular on test specimen surfaces to examine a cleaning method, spreading, decontamination, or substance release in such a way that, after treatment, the remaining matrix having a marker fraction is made visible by means of a dye or, at least after the marker has been removed, the marker is quantified by means of a PCR method. |
