Advances in biotechnology can be implemented by mimicking natural systems and processing, that are typically multifunctional, dynamic, environment responsive, at low energy consumption, produce minimum waste and no pollution. Nature evolved a number of strategies (material-structure) to create outstanding functional properties with “cheap base materials”. Using “green” procedure, starting from raw polymers isolated from different organisms, biopolymers can be manipulated by composition and structure obtaining multi-functional systems required for the cellular regeneration.

Abstract
Advances in biotechnology can be implemented by mimicking natural systems and processing, that are typically multifunctional, dynamic, environment responsive, at low energy consumption, produce minimum waste and no pollution. Nature evolved a number of strategies (material-structure) to create outstanding functional properties with “cheap base materials”. Using “green” procedure, starting from raw polymers isolated from different organisms, biopolymers can be manipulated by composition and structure obtaining multi-functional systems required for the cellular regeneration. This concept has been extensively studied and applied in the last years to the design and fabrication of scaffolds for tissue engineering strategies. In addition, many natural materials possess unique properties in terms of cross-talk ability with the system biological environment in particular with the regeneration process. The lecture regards basic concepts on the use of natural based polymers for the fabrication of bioactive scaffolds for tissue engineering applications, and specific examples will be presented on silk-derived constructs with processing-related bioactivity.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione
