Following the DigNA portoflio in-person meeting in Prague, the international conference on DNA data storage and other DNA nanotechnologies was held in the House of Porfessed in Prague, from 3rd to 6th of June, 2025.

Members of the TextaDNA team presented the project during Hot Topic sessions to specialists of computer science, DNA technologies, companies and researchers alike.

Dr. Cecilia Weltz presented her work on the development of a polymeric fiber library to store information-bearing oligonucleotides for non-destructive data retrieval. Taking advantage of intrinsic chemical properties of polymers, but also applying processes such as crosslinking, she showed water resistance of the fibers and the ability to store and retrieve DNA on demand.

PhD student Jokin Yeregui shared his preliminary work on random access based on stimuli-responsive lipid vesicles. Taking advantage of the chemistry of the lipid compostion of vesicles, he was able to demonstarte selective release of DNA under different experimental conditions, laying the first foundations of a non-PCR based system for random access!

Both talks led to some discussions with other projects about our storage system characteritics, and shows promising interest for the furutre of TextaDNA! Members of the project could also participate to enriching discussions about the field, going back to the lab with new ideas and renewed motivation!
