What You Need to Know
The process overcomes surface tension by applying 10–30 kV to a 5–15 % w/v protein solution, causing a charged jet that elongates and solidifies as the solvent evaporates. The resulting fibers can be tuned in diameter (100 nm–5 µm) and mechanical properties by adjusting concentration, voltage, tip‑to‑collector distance, and ambient humidity, and are often cross‑linked post‑spinning to enhance stability.
