FPs images on different surfaces (a–d) non-porous, (e–h) porous, and (i–l) semi-porous substrates developed by spraying with FDIP solution followed by PVA masking and visualized under UV 365 nm irradiation. The corresponding grayscale images are shown in Fig. S7; (m–o) 3-dimensional interactive plots of the corresponding FP (d,e,k), which reveals the uniform distribution of the prepared solution over the ridges (Scale bar: 5 mm).
