Abstract

Paper, as a material, has been attracting considerable attention for developing analytical devices and sensors after the introduction of a simple and easy method for patterning hydrophobic materials on paper. In this study, a survey is conducted and statistical data are produced by taking into account a number of published articles on paper research for the last 10 years since 2008. Technologies related to patterning hydrophobic materials on paper, namely, wax printing and photolithography methods, are also introduced. Accordingly, representative cases of using paper as a material to develop analytical devices and sensors have been introduced in the biomedical, food safety, agriculture, and environment fields. The use of paper in the development of analytical devices and sensors provides the following advantages: i) no need for additional apparatus to operate; ii) biomolecules can be immobilized using cellulose surface chemistry; iii) simple and reproducible patterning on paper; and iv) easy to carry, use, and dispose of the single-use sensor. The number of studies that refer to paper or paper microfluidics, particularly for developing analytical devices and sensors, are expected to constantly increase and gain popularity in various fields.
