FNP TEAM Project “Merging Programmable DNA Nanorobots and Microfluidics for Orientationally Controlled Delivery of Membrane Proteins to Protocells” (POIR.04.04.00-00-3CC0/16-00)
Total Award: 5,859,716 PLN, 100 % contribution from the European Regional Development Fund.
In our FNP-funded “TEAM” project we are using DNA as a building material to design and build novel nanostructures that will be able to interact with proteins in programmable ways. Find out more about FNP TEAM funding below. On this page we will keep you updated on out TEAM members, publications and other news.
Our project is in an area we refer to as “bionanoscience” – using biological molecules to build new, functional structures. This FNP (EU funding) research has allowed us to design hybrid DNA-lipid-protein structures aimed at controlling membrane proteins – a form of molecular robotics. Our extension to the grant has pushed us to extend our techniques further to develop new vaccine technologies.
Effect of the project: As well as the publications listed below, we hope that the project will lead to a new capabilities in bionanoscience and nanorobotics and, hopefully, lead long term to useful applications in therapeutics.
There has also been some unexpected benefits and synergy from our work- our expertise in handling lipids using lipid nanodiscs led to a successful collaboration with Konstantinos Beis at Imperial College culminating in our recent Science Advances paper reporting the structure of SbmA transporter protein.

We show that the opening and closing of a DNA origami box can be controlled by molecular locks that respond to a malarial diagnostic signal.
