(a) Representative electrospinning parameter optimization for the PONB-Butyl polymers varying fiber diameter: (i) 340 ± 112 nm, (ii) 395 ± 113 nm, (iii) 531 ± 108 nm, (iv) 739 ± 149 nm by altering the polymer concentration and flow rate at a 9 cm working distance: (i) 2.5%, 3 mL/h, (ii) 3.5%, 3 mL/h, (iii) 4.5%, 3 mL/h, (iv) 4.5%, 6 mL/h. (b) Optimized nanofiber meshes with approximately the same fiber diameters: (i) Butyl-Biotin mesh 694 ± 159 nm, (ii) diTEG-Biotin mesh 709 ± 240 nm, (iii) Butyl only mesh 640 ± 138 nm, (iv) diTEG only mesh 652 ± 130 nm (one-way ANOVA, p = 0.534 between the four NFM types, n = 20 fibers per mesh type) (scale bars = 5 µm).
