Article Title: Features in Microfluidic Paper-Based Devices Made by Laser Cutting: How Small Can They Be?

doi: 10.3390/mi9050220

Figure Lengend Snippet: Testing small-scale channels of different width with dye solution to determine the smallest channel width that can be fabricated from a particular paper type. Channels fabricated from RC-55 are shown in the figure. The actual width is listed as N/A for cases where the channel failed to provide a continuous flow path and so no successful width could be listed.

Article Snippet: In this experimental study, we determine the smallest feature sizes that will still enable fluid flow for five different types of paper: (i) Whatman 1 Chr chromatography paper (1 Chr), (ii) Whatman 3MM Chr chromatography paper (3MM Chr), (iii) Whatman regenerated cellulose membrane 55 (RC-55), (iv) Whatman filter paper grade 50 (FP-50), and (v) Amershan Protran 0.45 nitrocellulose membrane (NC).

Figure Lengend Snippet: ( a ) The smallest channel widths in each of the paper types for successful fluid flow plotted against fiber widths. SEM images of the channels generated in the different paper types showing one intact channel with successful fluid flow (on the top) and one narrower channel where fluid flow was not successful (on the bottom), for ( b ) FP-50, ( c ) 3MM Chr, ( d ) 1 Chr, and ( e ) RC-55.
