Coaxial electrospinning uses a spinneret with two concentric nozzles to produce core-shell nanofibers — a distinct inner core inside an outer shell. Linari NanoTech supplies modular and sealed coaxial needle kits that integrate with our systems and with third-party setups, so you can encapsulate drugs, protect sensitive cores, and combine materials that cannot be spun on their own. Why core-shell fibers - Protect a sensitive core: The shell shields fragile payloads — proteins, growth factors, or drugs that degrade on contact with solvents, oxygen, or moisture. - Control and sustain release: A shell barrier slows and smooths the release of a drug held in the core, avoiding a sudden burst and extending it over time. - Spin the unspinnable: A spinnable shell can carry a core that could not form a fiber alone, including some liquids and non-spinnable actives.
