Project ID: 237224
Funded under: FP7-PEOPLE

Abstract

NANOPHOTOCHROME aimed to combine the nanotechnology and genetic engineering, where genetic engineering develops RC and bR variants with biological functions adapted to specific application and nanotechnology develops QDs specifically selected to be optically coupled with the PIMP chromophores and with surfaces functionalised to form complexes with biomembranes or to be chemically tagged with desired amino acid residues of bR or RC.

Their report lists their main achievements, in particular:
(1) development of the nano-bio hybrid materials for enhanced photosynthesis in artificial light harvesting and energy trasmitting systems;
(2) development of the nano-bio hybrid materials for photovoltaic applications;
(3) energy transfer within hybrid materials and within the immunocomplexes for multiplexed high throughput detection of rare cancer cells in view of development of advanced diagnostics of a breast cancer micro-metastases.

This study represents the first example of the efficient transfer of excitation energy harvested by nanoparticles to a complex biological photosynthetic system. The results are important because they pave the way for the use of nanocrystals as light-harvesting built-in antennae for artificial photosynthesis. It is worth mentioning that the enhancement of biological functions of natural photosynthetic systems should have a strong impact on energy-related technologies. The report also includes images.
