Solving ocular drug delivery challenges by applying DNA technology

nano-I-drops is a research project on ocular drug delivery at the University Eye Hospital Tübingen (Germany) aiming to transfer nanoparticles made of natural building blocks from research stage to clinical application.


Our DNA nanoparticles show excellent adherence to the ocular surface leading to increased drug uptake and improved efficacy. This allows for a much lower drug concentration and less frequent application and thereby reduced side effects.




Our nanoparticles consist of lipid-modified DNA-strands that self-assemble into micelles with a hydrophobic core and a hydrophilic corona. Various substances can be loaded via three different strategies:


I)   hydrophobic loading into the core

II)  covalent binding to the complementary DNA-strand

III) aptameric loading

Collaboration opportunities

nano-I-drops technology can be combined with a wide variety of ophthalmic drugs, including the ones that have been abandoned due to severe side effects or lack of formulation.




We are currently addressing several segments of the ophthalmic market. First results on therapy options for glaucoma and anti-infectives are very promising.
