Herein we demonstrate the ability to fabricate polymeric microtubes with an inner diameter of approximately 3 microm through co-electrospinning of core and shell polymeric solutions. The mechanism by which the core/shell structure is transformed into hollow fibers (microtubes) is primarily based on the evaporation of the core solution through the shell and is described here in detail. Additionally, we present the filling of these microtubes, thus demonstrating their possible use in microfluidics. We also report the incorporation of a protein (green fluorescent protein) within such fibers, which is of interest for sensorics.
在此,我们展示了通过共电纺核壳聚合物溶液制造内径约为3微米的聚合物微管的能力。核壳结构转变为中空纤维(微管)的机制主要基于核溶液通过壳层的蒸发,在此进行详细描述。此外,我们展示了这些微管的填充情况,从而证明了它们在微流体中的潜在用途。我们还报告了在这种纤维中掺入一种蛋白质(绿色荧光蛋白),这在传感领域具有重要意义。
