Project Summary: BIosINTEL project aim is engineering smart bio-interfaces with multiple and synergetic functionalities for effective controlled regulation of stem cell differentiation and low inflammatory response for enhanced osseointegration. The innovative strategy within the project proposed is:
-Smart surface design: multiscaled microstructured surfaces obtained by laser processing technique
-Innovative hierarchical nanostructuring of the microstructured surfaces by tailoring the self assembling of biocompounds and biodegradable polymers spherulites formation
-Specific laser based functionalization of surfaces (by matrix assisted pulsed laser evaporation and LIFT)
-Effective use of hierarchically patterned topography for tuning biointerface characteristics to stem cell differentiation.
The design model based on tailored topographical and chemical cues for quantifying the steering of stem cell has impact in basic cell researches and tissue engineering application.
 

General objective:

The aim of BIosINTEL is the engineering of smart bio-interfaces with multiple and synergetic functionalities for effective controlled regulation of stem cell differentiation and low inflammatory response for enhanced osseointegration.
