Understanding wax screen-printing: A novel patterning process for microfluidic cloth-based analytical devices

Thread based electrofluidic platform for direct metabolite analysis in complex samples

“…Due to this simplicity and functionality, a variety of applications have been demonstrated using two main platforms over the last few years. First, and similar to paper-based microfluidics, are the two dimensional patterned or woven fabric-based microfluidic devices [14][15][16][17][18][19][20][21][22][23]. The second group are based upon single threads, which generally involve much smaller solution volumes, as in these examples the flow within the strands of the thread is confined to one direction.…”

Facile and sensitive chemiluminescence detection of H2O2 and glucose by a gravity/capillary flow and cloth-based low-cost platform

“…Within these mCADs, colorimetric, 39,42 electrochemiluminescence 41,43,44 or CL 40,46 methods have been applied for determination of H 2 O 2 or glucose. Relative to the two former methods, the CL method indeed exhibits some advantages mentioned above.…”

Laser-induced selective wax reflow for paper-based microfluidics

“…12 Wax is one of the most commonly used materials to form hydrophobic barriers in cellulose ber, since the wax has the advantages of easy accessibility, ultra-low-cost, non-toxicity, and ease of processing with heat. Several approaches have been made for the deposition of designed wax patterns on the surface of bulk paper material, including wax printing, 13 wax screenprinting, [14][15][16] wax stamping, 17 wax dipping, 18 wax jetting, 19 and even hand painting with crayon. 20 Aer the deposition of designed wax patterns, a thermal reow process is usually required using a hotplate to allow the wax to penetrate through the whole thickness of the paper.…”
