As can be seen in Figures , the fluorescent properties of the [n]CPP and PCL blend "inks" after solvent removal are well maintained. MEW, however, imparts challenging thermal conditions on the polymer to be processed, due to the nature of the technology . The mechanism to achieve small diameters for MEW is via extremely low flow rates to the nozzle, down to 2-5 µL.h - . This low throughput results in the polymer in the syringe remaining heated for substantial periods of time. Preferably [n]CPP-PCL blends must be thermally resistant for at least a week in such processing conditions, as there is convenience in not constantly replacing the syringe with fresh material. When printing with PCL, it is typically heated to 75 -85 °C. Therefore, any fluorophores to be included with the PCL must be thermally resistant at 85 °C for periods up to 1 week without significant loss in their fluorescent capabilities for a comparable duration. The jet speed for MEW was determined through measuring the critical translation speed (CTS), the collector speed at which the deposited fiber transitions from buckled to straight. This measurement can determine whether the inclusion of the [n]CPPs affects this important processing parameter. It was found that the addition of 0.01wt% [n]CPP did not affect the jet speed (610 mm.min -1 for [8]CPP-PCL; 620 mm.min -1 for [9]CPP-PCL; 620 mm.min -1 for [10]CPP-PCL), nor the general printability compared to PCL processed using the same solvent addition and removal steps. We found that dissolving the PCL in DCM and then removing the solvent affects the jet speed, increasing it from 350 mm.min -1 to 610-630 mm.min -1 . The solvent addition/removal steps likely decrease the melt viscosity and/or increases charge carriers within the PCL, resulting in the jet speed increase. Despite this increase in the jet collector speed for processed PCL and its [n]CPP-PCL blends, the consistency and stability were demonstrated using MEW. A scaffold design was composed of 40 layers of straight fibers spaced at 150 µm, where each next layer was rotated by 36° (180°/5 directions), printed with processed PCL and [8], [9], and [10]CPP-PCL then imaged on various scales under ambient and UV radiation. Figure provides the overview that visualizes the fluorescent capability of [n]CPP-PCL, ranging from the centimeter down to micrometer scale imaged with a digital camera then optical microscope. Furthermore, several tubular MEW scaffolds were designed with different morphologies, including a 30° angular displacement between each layer to generate structures not typical for a classically wound tube (Figure ).
