Figure 4: Anisotropic particle synthesis from organic precursors.
From: Non-polydimethylsiloxane devices for oxygen-free flow lithography
(a) Triangular particle synthesis with PEG 200 inert flows in an NOA channel from organic precursor containing PEGDA 200, ruthenium dye (mixed with methanol (MeOH) and toluene), and PI. (b,c) Brightfield and fluorescence images of triangular particles synthesized in (a). (d) Particle synthesis in an NOA device with water-insoluble monomers TMPTA and PUA, mixed with toluene and PI. Inert flows consisted of Tergitol surfactant to lower surface energy and prevent curvature in top and bottom faces of particle. (e,f) Images of particles synthesized from TMPTA and PUA. Scale bars, (b,c) 30 μm, (e) 100 μm, and (f) 50 μm.
