Splet09. jan. 2024 · PDMS wedge is placed between the cold source (copper plate dipped into liquid nitrogen) and the aqueous dispersion. Because of the nonhomogeneous thermal … PDMS wedges exhibited the least auto-fluorescence compared to NOA63 and ET302 wedges. Although both NOA63 and ET302 wedges were auto-fluorescent, high levels of fluorescence were limited to the edge of the wedges (Fig. 5). The edge fluorescence was an unavoidable curing-induced surface property.
