Sonia Antoranz Contera

Co-director OMS Institute of Nanoscience for Medicine.


I am a Spanish physicist, currently I work as an Associate Professor in Biological Physics at Oxford Physics Department.
My work lies at the interface of physics, biology and nanotechnology. I am an expert in atomic force microscopy of biological systems and I have a special interest in the role of mechanics in biology. We work on mechanics of cells, proteins and membranes and we design nanomaterials that mimic biological functions for bio/medical applications such as drug delivery or cell cultures. We are mainly dediated to quantitative aspects of these applications (transport and mechanics).
Recently I have started a new collaboration with Prof Ian Moore of Oxford Plant Sciences on the nanomechanical aspects of plant cells walls.

I am co-director of the Oxford Martin Programme on Nanotechnology (former Institute of Nanoscience for Medicine) at the Oxford Martin School and Fellow of Green Templeton College. I am a Member of the World Economic Forum Global Agenda Council on Nanotechnology 2014-2016 . Recently I have also become a member of the Physical Sciences Strategy Advisory Team of the Engineering and Physical Sciences Research Council (EPSRC) of the UK.
I have had career breaks after the births of my 2 children,one in 2008 and one in 2013.

I am a frequent public speaker on the role that Physics and Nanotechnology should (and will!) play in the future of Biology and Medicine and I have published several pieces on Nanotechnology for the general public, such as this one in WIRED magazine on six future forms, or this one on the World Economic Forum Agenda : Can nanotechnology reduce inequality?

I am a member of several international, multidisciplinary collaborations, such as the JSPS funded Core-to-Core programme on sensing devicesand the newly established International brain Mechanics and Trauma Lab. I also collaborate with the Scenarios Programme of the Oxford Said Business School.

I graduated in Physics from Universidad Autónoma de Madrid (93), then did graduate studies at Beijing Languages and Culture University (94-95) and worked as a researcher at the Czech Academy of Sciences with Prof. Zlatko Knor, one of the pioneers of atomic scale imaging of surfaces (95, liquid-solid interfaces with STM).
Then I moved to Japan on a Japanese Government Monbushō scholarship and got my PhD from Osaka University's Dept. of Applied Physics, Graduate School of Engineering (2000, Layered materials/scanning probe microscopy, with Prof H Iwasaki as supervisor ).

In 2000 I was awarded an E.U. Fellowship to Japan at the Institute of Scientific and Industrial Research SANKEN, Osaka University (nanostructures in bio/nanoelectronics). Later, I became a Research Assistant Professor in 2002, at the Interdisciplinary Nanoscience Centre, Univ. of Aarhus, Denmark, setting up an AFM lab for biological experiments in Flemming Besenbacher's iNANO centre (HIV-1 RNA tertiary structure, Nanoscience and tissue engineering approaches to improved biocompatibility).
In 2003 I moved to Oxford University Bionanotechnology IRC (carbon nanotube biosensors, bionanointerfaces, and biophysics of membrane proteins, scanning probe microscopy).

In 2007 I became a lecturer and RCUK Academic Fellow at Oxford Physics and in 2008 started the Institute of Nanoscience for Medicine at the Oxford Martin School, which I still codirect.

I work with labs all over the world and I have been a visiting professor at Kwazulu-Natal University Medical Faculty in South Africa, to set AFMs for HIV research, and at Tabata's lab at Tokyo University's Centre for BioNano Integration for appplication of THZ spectroscopy to biological membranes; I have had research stays at Ando's high-speed AFM lab in Kanazawa University and Moscow Lomonosov State University.


I am member of several networks and research collaborations:
Oxford Martin Programme on Nanotechnology
JSPS funded Core-to-Core programme
International brain Mechanics and Trauma Lab.

I collaborate with researchers all over the world -which if the best part of the job!- right now I am working with:

  • Dr Kislon Voitchovsky (Durham U) on interfaces with AFM
  • Dr Isabel Llorente (UCL) in micro and nanomanipulation of carbon nanoparticles in solution
  • Dr Sonia Trigueros in nanomedicine projects
  • Eneko Axpe (UPV/EHU), nanomechanics or biopolymers and lipids combining AFM and Positron Annihilation Spectroscopy
  • Jihan Zhou, Prof Dehai Liang, Peking University, Nanomechanics of lipid-based nanostructures

  • Shingo Makishi and Chikara Dohno from SANKEN, Osaka University, DNA nanostructures on lipid bilayers.


In the past I have collaborated with Prof. Arvind Raman (Purdue), Prof. Hiroshi Iwasaki (Osaka U), Prof. Hiroyuki Noji (Tokyo U), Prof. H. Tabata (Tokyo U), Prof. Sergi Civit (U Barcelona), Dr. Roger Proksch (Asylum Research), Dr Stephan Grage (Karlsruhe), Prof. Ando's AFM lab, ... and a lot of great researchers!


  • My small article entitled "Designer cantilevers for even more accurate quantitative measurements of biological systems with multifrequency AFM" has been accepted for publication in Nanotechnology. It is a Perspective on this work by Luna's lab.
  • POSTDOC POSITION: we will be hiring an experimental postdoc soon, to work on mechanical aspects of biological systems with AFM. Interested candidates can contact me directly by email even before the official advert at the university website goes live.

  • 5 February 2016 I am delighted to have been invited to be the speaker of one of the School of Physics colloquia at Trinity College Dublin.
  • 6-7 July 2016 in 2016 the Royal Society of Microscopy's SPM meeting will take place at Warwick University and I have been asked to be the chair of the AFM in Biology session, which will be about forces and mechanics in Biology. Join us!

Our recent paper "Sub-nanoscale free volume and local elastic modulus of chitosan/carbon nanotube biomimetic nanocomposite scaffold-materials" selected to the 2015 Journal of Materials Chemistry B Hot Papers (J Mat Chem B's impact factor 4.726)

This paper describes new methods that enable to measure and to desing two key parameters of future materials for drug-delivery and tissue engineering: nanoscale mechanical properties and crucially mass transport (free volume) using atomic force microscopy (AFM) and positron annihilation spectroscopy (PALS).
The authors of this work are: Eneko Axpe, Loic Bugnicourt, David Merida, M. Goiriena-Goikoetxea, Iraultza Unzueta, R. Sanchez-Eugenia, Jose Angel Garcia, Fernando Plazaola and Sonia Contera.

Paper accepted in Nanoscale Aug 2015, Nanoscale impact factor is 7.394.
"Effect of intra-membrane C60 fullerenes on modulus of elasticity and mechanical resistance of gel and fluid lipid bilayers" By Jihan Zhou, Dehai Liang and Sonia Contera
C60 fullerenes stiffen lipid bilayers but they decrease their mechanical resistance, our results have implications for drug delivery and nanotoxicity of C60 particles.
