A Photonastic Prototissue Capable of Photo-Mechano-Chemical Transduction

The Gobbo Group has created the first light-responsive artificial tissues-like materials, or photonastic prototissues, that can mimic natural energy transduction processes. Published in Advanced Materials, the work combines gold nanoparticle-based proto-organelles and a responsive polymer “proto-cortex” to build protocells that contract under visible light. These motions can reversibly control internal enzyme activity, offering a new way to engineer life-like behaviours. This advance marks a significant step towards advanced, energy-responsive prototissues in synthetic biology and bioinspired materials engineering.

Shining Light on Carbon Dots: New Opportunities in Photocatalysis

Our ChemCatChem Concept Article is now published. The article discusses recent advancements in carbon dots-based photocatalysis. We highlight the link between the carbon dots superficial and core composition and their resulting photo-redox abilities. We then give future perspectives on their application in cutting-edge areas. The work was carried out in collaboration with Dr. Giacomo Filippini and Prof. Maurizio Prato at the University of Trieste.
