The optimised values of the operating parameters for spinnability and brief highlights of the morphology of the fibres in the scaffolds.

Fibre composition	Viscosity (P), flow rate (μL/min), and voltage (kV)	Observed morphology
Alginate	68.4 p ± 0.08, 8–10, and 26	Diameter of 62–180 nm; randomly oriented and continuous; ultrafine, wavy, and smooth surface; beads-free
Alginate/MgO 10% (w/w)	72.2 p ± 0.0, 8–10, and 26	Diameter of 83–230 nm; randomly oriented and continuous; ultrafine, wavy, and smooth surface; beads-free
