Who we are

We are a group of scientists at the Cavendish Lab, University of Cambridge, UK. Our research is focused on understanding transport processes through membranes for biosensing applications.

Since the pandemic we are mainly interested in understanding RNA, its structure and its relation to biology and disease. More details on our current and past research interests can be found here. Since the start, the lab aims to achieve a maximum level of control over all parameters in our experiments. Our main technique remains resistive-pulse sensing with nanopores especially in combination with DNA and now RNA nanotechnology

Our interdisciplinary team combines researchers with expertise in physics, engineering, physical chemistry, biochemistry/biology, and micro- and nanofabrication.

In case you are interested in working with us, please get in touch with Ulrich by email: ufk20 (at) cam.ac.uk.

We gratefully acknowledge funding of our work from various sources including:

7/8/2023 dCas9 screened with nanopores.

Sarah - in collaboration with Richard Gutierrez from ONT - investigates the binding efficiency of dCas9 to DNA sequences. In her nanopore 'tour de force' Sarah used designed DNA nanostructures for screening dCas9 target sequences with single basepair resolution. Her paper just appeared in Nature Biomed. Eng. Congratulations to Sarah for the great work and excellent collaboration with ONT!

26/7/2023 DNA signals depend on everything.

Check out Yunxuan's recently published paper in Nano Letters that reveals the relationship between DNA sequence and nanopore signals. It is all a bit more complicated and interesting than just molecular weight of the molecules. Congratulations to Yunxuan, Sarah and Jinbo (as senior author)!

5/7/2023 DNAo nanocavities.

Congratulations to Sara for her recently published paper in Nano Letters. In collaboration with the Baumberg lab Sara used DNA origami nanostructures as a spacer to create plasmonic cavities in the NanoParticle On Mirror (NPoM) geometry. By decorating her DNA constructs with quantum emitters, the interaction of single light emitting molecules with gold atoms protruding from tightly confined plasmonic cavities can be studied. This opens up the possibility of new nanophotonic devices. Well done!

3/7/2023 July 2023 update.
The Radenovic and Fantner labs at EPFL characterised our DNA carrier systems with controlled nanopipette translocation. Read the full story in Nature Nanotechnology now. Otherwise we are getting ready for the summer conference and workshop season. Yunxuan attended the Faraday discussion on Ionotronics in June. Frank and Ulrich will be in Lyon for the Nanofluidics in Physics and Biology organised by Fabien Montel.
