Figure 4 . Colony-LAMP assay for E. coli and P. aeruginosa colonies. a) Images of the colonies picked fromE. coli plate. R: Colony diameter, E. coli : Rmin ≈ 1.437, Rmean ≈ 1.744, Rmax ≈ 2.281 mm, P. aeruginosa : Rmin ≈ 1.537, Rmean ≈ 1.853, Rmax ≈ 2.012 mm. b) Colorimetric Colony-LAMP reactions in the PDMS wells. Pink color indicates the negative, yellow color shows the positive results. Electrophoresis results forc) E. coli, d) P. aeruginosa colonies. L: DNA ladder, N: Negative control.
