A highly porous, biocompatible composite patch is designed for drug loading using TEMPO-oxidized nanocellulose as support for compositions that include conductive polymers. The system allows for electro-responsive effects, which are most desirable for electrostimulation. This also requires a required elasticity to allow for material deformation. The material design is facilitated by 3D printing in a layered, lattice structure whereby the nanocellulose endows the system with the required porosity, in the micron-scale as well as biocompatibility. An antibacterial prescription medicine is used to test the drug release potential of the 3D printed patches, which are also shown to enable cell attachment. This bio-based, elastic and conductive composite shows promises for application in biomedicine.
