Nanosilicon-Based Photosynthesis for Chemical and Biomedical Applications (PSY-NANO-SI) - Publishable Executive Summary

Project ID: 13875
Funded under: FP6-NMP


The overall goal of the project is to explore the possible applications of silicon nanocrystals (nano-Si) as efficient generator of singlet molecular oxygen (1O2), and develop novel biologically tolerable and environmentally friendly prototype systems, able to compete with existing photo-sensitizers in photochemical, biological and medical applications.
Five teams constitute a PSY-NANO-Si Consortium; three of them are the European leaders in major issues related with nano-Si from its fabrication to effective control of its structural and morphological properties. A Japanese partner, the Kobe University team, is a world-class center specialized in investigations of the optical properties of the silicon nano particles. Inclusion into the consortium of the outstanding partner team from Catholic Leuven University dedicated to biological and therapeutic applications of singlet oxygen 1O2, guarantees achievement of the tasks related to the planned biomedical applications.
The Scientific and Technological objectives of the entire Project are:
- Research and development of technological processes for the formation of nano-Si materials with controllable shapes and sizes of particles;
- Comprehensive study of nano-Si as a photo-sensitizer material for generation of singlet oxygen in a gas and liquid phases;
- Study of delivery mechanism of nano-Si to local zones where its action is necessary and development of photodynamic therapy employing nano-Si
