Dr. Vladimir Baulin
- Vladimir Baulin is a Coordinator of EU funded Initial Training Network SNAL: Smart Nano-objects for Alteration of Lipid bilayers.
- Guest editor of the web themed issue “Interaction of nano-objects with lipid membranes” in Soft Matter journal.
- Develops Single Chain Mean Field (SCMF) theory, a simulation tool able to predict the properties of nanostructures given the microscopic details of its polymeric constituents. Recent application of the SCMF theory is the modelling of interaction of phospholipid bilayers with nano-objects and self-assembled structures.
- Designs nano-structured antibacterial surfaces inspired by insect wing surfaces.
- Works on a theoretical model for orientation of microtubules, constituents of cell cytoskeleton. This mechanism of microtubule orientation induced by mutual collisions between individual microtubules in 2D and 3D leads to global ordering and formation of orientation domains.
- Contributes to Poisson-Boltzmann theory of interpolyelectrolyte complexes with IPEC Solver.

- Direct proof of spontaneous translocation of lipid-covered hydrophobic nanoparticles through a phospholipid bilayer
Science Advances 2 (11), e1600261 (2016)
Yachong Guo, Emmanuel Terazzi, Ralf Seemann, Jean Baptiste Fleury and Vladimir A. Baulin
Hydrophobic nanoparticles introduced into living systems may lead to increased toxicity, can activate immune cells, or can be used as nanocarriers for drug or gene delivery. It is generally accepted that small hydrophobic nanoparticles are blocked by lipid bilayers and accumulate in the bilayer core, whereas big nanoparticles …

- Peroxidised phospholipid bilayers: insight from Coarse-Grained Molecular Dynamics simulations
Soft Matter, 12, 263-271 (2016)
Yachong Guo, Vladimir Baulin and Fabrice Thalmann
An original coarse-grained model for peroxidised phospholipids is presented, based on the MARTINI lipid force field. This model results from a combination of thermodynamic modelling and structural information on the area per lipid, which have been made available recently. The resulting coarse-grained lipid molecules form stable bilayers, and a set of elastic …
- Self-organised nanoarchitecture of titanium surfaces influences the attachment of Staphylococcus aureus and Pseudomonas aeruginosa bacteria
Applied Microbiology and Biotechnology (2015) 99 (16), 6831-6840 DOI: 10.1007/s00253-015-6572-7

The surface nanotopography and architecture of medical implant devices are important factors that can control the extent of bacterial attachment. The ability to prevent bacterial attachment substantially reduces the possibility of …
- Efficient and Stable Method to Solve Poisson–Boltzmann Equation with Steep Gradients
Computational Electrostatics for Biological Applications
2015, pp 111-119 DOI: 10.1007/978-3-319-12211-3_5
Beibei Huang and Vladimir A. Baulin
This work describes a method to solve Poisson–Boltzmann Equation (PBE) with steep gradients when common methods of solving non-linear equations do not converge or work inefficiently. This is particularly the case for relatively large boundary conditions leading to rapid changes of the solution in a narrow interval. The method uses adaptive …
- Mechanism of dynamic reorientation of cortical microtubules due to mechanical stress
Biophysical Chemistry, (2015) 207, 82–89 DOI: 10.1016/j.bpc.2015.09.004
Alexander Muratov and Vladimir A. Baulin
Directional growth caused by gravitropism and corresponding bending of plant cells has been explored since 19th century, however, many aspects of mechanisms underlying the perception of gravity at the molecular level are still not well known. Perception of gravity in root and shoot gravitropisms is usually attributed to gravisensitive cells, called statocytes, which exploit …
