The techniques of the formation of micro- and nano-patterns on surfaces with regard to chemical and biological substances is essential in sensor technology. These techniques have been summarized in a review by Hook, Voelcker, and Thissen (1). More detailed references can be found in this particular review. An overview of patterning techniques is given in Table 2.1.
|Contact and noncontact printing||Quick and simple pattern formation||Poor resolution, pattern dimensions limited|
|Electron beam lithography||Highly resolved patterning, no need for a mask||Slow processing time, clean environment required, expensive|
|Dip pen nanolithography||Highly resolved patterning, high energy particle beams not required.||Slow processing time|
|Photolithography||Highly resolved patterning, large surface areas||Rigorous experimental protocols.|
|Templating||Low cost, quick and highly resolved||inert environment, dimensions and geometries restricted|
|Imprint lithography||Low cost, high resolution||Limited number of molecules and substrates|
|Microcontact printing||Simple method||Limited number of molecules and substrates|
|Micromoulding||Experimentally simple||Limited pattern geometries|
|Magnetic force based patterning||Directly patterns cells and biomolecules||Conducted in an inert environment|
