Characterization of fluorescence intensity from (a) TMV1cys functionalized on planar Au and μPA electrodes displaying SARs ranging from 3.3 to 10 (scale bars: 100μm). (b) A significant increase in functionalization density is achieve with the μPAs as reflected in the increase in fluorescence intensity (N=5).

... fluorescent microscopy images taken from the printed spots on different electrode geometries. Under an identical exposure time, TMV1cys printed on μPA electrodes resulted in a significantly higher fluorescence compared to the planar electrodes with an excellent patterning fidelity (Figure 5a, bottom-right), due to the underlying microstructure. However, there is a noticeable discrepancy between the change in increment factor of the fluorescence intensity and the SAE factor calculated based on the μPA geometry (Figure 5b). ...

However, there is a noticeable discrepancy between the change in increment factor of the fluorescence intensity and the SAE factor calculated based on the μPA geometry (Figure 5b). This is attributed to the lower density of TMV1cys on the high SAR μPAs as supported by the SEM characterizations in Figure 4a, indicating that control over concentration of bio-ink may need to be optimized to obtain highly controllable functional scalability of the resulting nano/micro/bio- integrated components. ...
