Colored nano-lights allow data to be stored more efficiently by means of Dna: this is the goal of the Dna-Fairylights project, coordinated by Italy, with the Italian Institute of Technology (Iit) and financed by the European Union. , under the Horizon 2020 framework program, with 3.1 million for the next 3 years.



Archiving of digital data through DNA is an innovative technique being studied to have, in the future, efficient and low-cost alternatives to archive data and the aim of the European project is to mark DNA sequences with colored nano-lights, in in order to have faster data reading and writing processes and new coding approaches.



Coordinated by Roman Krahne and Denis Garoli, from the IIT Optoelectronics group, the project involves an interdisciplinary research group in which groups from Italy, Spain, Germany, France, Switzerland and the United Kingdom participate.



Currently digital data is stored in the form of bits as a series of ones and zeros, and each individual is estimated to generate several billion bits to be stored on devices such as mobile phones, smart watches, computers, tablets. The challenge is therefore to be able to analyze the data in the most energy-efficient way and a promising solution is to use DNA molecules to convey the information.



This solution would allow unprecedented storage capacity, long-term stability and low manufacturing costs.

However, there are some obstacles to overcome, such as the long times required to read the DNA sequence and for the reconfiguration at the base of the reading and writing processes, in addition to the high costs to synthesize the desired DNA sequence.



Overcoming these obstacles is the goal of the European project and the means to do so is to replace the binary code with colors: the latter, integrated in a DNA sequence, allow information to be encoded in a more compact and efficient way.

The colors are then read by optical technologies quickly.

The aim is to develop new nanomaterials for optical coding, new algorithms for data storage and innovative reading devices.
