Biochemical method of examining or structuring a surface or surface layer

摘要

The invention relates to a method for investigating the surface of an object for a topographical and/or chemical characteristic. According to said method, the surface of the object is subjected to the action of surface structure selective (for investigating a topographical characteristic) and/or chemoselective (for investigating a chemical characteristic) biocomponents and a nutrient- or osmotic protective medium in such a way that the biocomponents in the nutrient- or osmotic protective medium are in contact with the object surface or are at a distance from the object surface which is within their range of detection. The object surface is then investigated using the biocomponents in the nutrient- or osmotic protective medium and at least one investigation measuring value is determined. The investigation measuring value is then compared to a reference measuring value and the result of this comparison is used to draw conclusions as to the topographical and/or chemical characteristics of the object. The invention provides a simple, very precise method for investigating the surface of an object for a topographical and/or chemical characteristic.
