Watermarking for Paper-Based Digital Microfluidic Biochips
2020 IEEE International Test Conference in Asia (ITC-Asia), 2020Paper-based digital microfluidic biochip (PB-DMFB) technology provides a promising solution to many biochemical applications. However, PB-DMFB manufacturing process may suffer from potential security threats. For example, both Trojan insertion and man-in-the-middle attack may affect the functionality of PB-DMFBs.

Isoelectric focusing on microfluidic paper-based chips
Analytical and Bioanalytical Chemistry, 2019Isoelectric focusing (IEF), a powerful technique for protein separation and enrichment, was successfully integrated into microfluidic paper-based analytical devices (μPADs) in this work. The μPADs for isoelectric focusing were fabricated by octadecyltrichlorosilane (OTS) silanization and subsequent region-selective plasma treatment.

Isotachophoretic Preconcenetration on Paper-Based Microfluidic Devices
Analytical Chemistry, 2014Paper substrates have been widely used to construct point-of-care lateral flow immunoassay (LFIA) diagnostic devices. Paper based microfluidic devices are robust and relatively simple to operate, compared to channel microfluidic devices, which is perhaps their greatest advantage and the reason they have reached a high level of commercial success ...
