  • Electrospraying System

    Electrospraying System

    The in-house developed electrospraying system allows for the creation of spherical hydrogels from low-concentration polymer solutions, such as alginate and agarose, by applying an electric field. This process, also known as electrohydrodynamic spraying, is used for encapsulating cells for immuno-isolation and containing drugs to enable the controlled release of medication. The size and viscoelastic properties of hydrogels are determined by important process parameters such as polymer concentration, flow rate, and the strength of the electric field. The needle or nozzle configuration (single needle, coaxial nozzle) can produce solid spherical hydrogels, multi-structural hydrogels (beads in beads), and core-shell structures. This process is frequently employed in biomedical technology to encapsulate drugs.

  • Elektrospinning

    Elektrospinning

    The in-house developed electrospinning system is used to produce polymer fibres from various solutions by applying an electric field in a horizontal orientation. This technique enables the production of artificial nano- and microstructured fibre mats, which can be used to develop scaffolds for artificial blood vessels, heart valves, skin, and more. The high voltage charges the viscoelastic liquid droplets. If the electrostatic repulsion caused by surface tension is overcome, the droplet expands and forms fibres.  The gelled fibres are collected on the collector. Different collector geometries and rotation speeds can influence fibre orientation and the 3D appearance of the scaffolds. This process is frequently used in biotechnology, energy technology, and medical technology.
