Development of paper-based analytical kit for point-of-care testing.

Paper-based analytical devices have been widely used for biomedical, environmental and food-quality testing. This review focuses on paper-based tests for biomarkers and bacterial detection with a brief introduction about various fabrication techniques and designs, biological and nonbiological probes and detection methods. Paper is relatively cheap and available in abundance. Moreover, properties of paper such as it being disposable, easy to use and store, and that it is easy to transport and modify draw significant attention to it as a platform for the development of paper-based analytical devices. These traits make paper-based analytical devices a strong candidate in point-of-care devices for rapid and economical testing near the site of patients.
