本文报道了一种简单而有效的方法来控制统计孔径分布内的静电纺丝纳米纤维膜（ENMs），通过选择适当的旋转时间的静电纺丝沉积。随着纺丝时间的增加，ENMs的平均孔径呈指数下降。这种孔径控制方法被证明可以调节到达微流体种子生长芯片（SGC）的热能的量，从而调节芯片上种子的生长温度，而不使用复杂的半导体制造技术或额外的芯片上电子电路。减小ENM的平均孔径导致片上温度降低，遵循二阶多项式趋势。基于实时观察根构型的表型研究是在不同温度条件下对多个SGCs进行的，所述多个SGCs是通过使用具有不同孔径分布的ENM获得的。
This paper reports a simple and effective approach to control statistical pore size distributions within electrospun nanofibrous membranes (ENMs), by choosing appropriate spinning times of electro-spinning deposition. Mean pore diameter of ENMs decreases exponentially with increasing spinning time. This pore-size control method is demonstrated to regulate amount of heat energy reaching microfluidic seed growth chips (SGC) and thus growth temperature of seeds on the chips, without using sophisticated semiconductor manufacturing techniques or additional on-chip electronic circuits. Decreasing mean pore diameter of ENMs causes to decrease the on-chip temperature, following a second-order polynomial trend. Phenotypic study based on real-time observation of root architecture is conducted on multiple SGCs under various temperature conditions obtained by using ENMs with different pore size distributions.
