Characterization of Electrospun Nylon Layers of the Cell Delivery Vehicles

Si CDV Pore Size1 (Standard deviation) microns Ny CDV Pore Size1 (Standard deviation) microns Si CDV Fiber Size2 (Standard deviation) microns Ny CDV Fiber Size2 (Standard deviation) microns
Outer Electrospun Layer 2.04 (0.02) 1.91 (0.36) 0.57 (0.03) 0.66 (0.05)
Inner Electrospun Layer 0.39 (0.03) 0.25 (0.01) 0.22 (0.02) 0.12 (0.01)

Pore size was quantified from scanning electron micrographs imported into Metamorph image processing software. Measurements were calibrated using the scale bar embedded in the image. Pores (i.e., void areas bordered by electrospun fibers) were outlined, forming polygonal regions. The area of each region (i.e., the pore area) was calculated. The areas were then used to determine diameters of equivalent circles (i.e., assume the pore areas to be circular and calculate diameters). The resulting diameters are the “pore sizes.” Results are based on 3 devices for outer layer and 2 devices for inner layer and 32 measurements per device.
