Materials integration. a) Fluorescence image of lipid dot patterns from different inks (1 Mol % Rhodamine-DOPE, 2 Mol % Marina Blue-DHPE, and Carboxyfluorescein-DOPE, respectively) printed onto a glass slide, demonstrating material integration. Bar = 200 μm. b-d) 40× fluorescent images of Rhodamine-PE, Marina Blue-DHPE, and Carboxyfluorescein-PE doped patterns shown in panel (a); Bar = 10 μm. e) 10×10 dot pattern array of DOTAP doped with 1 Mol % Rhodamine-DOPE, Marina Blue-DHPE, and Carboxyfluorescein-DOPE for red, blue and green fluorescence, respectively. This demonstrates the scalability of nanointaglio for printing different lipids onto the same surface without significant cross contamination. Shown is 100 lipid patterns printed over and area of ∼15 mm2. Scale bar = 200 μm.
