Extraordinary doctoral award

Ingrid Cabrera, member of the NANOMOL group that coordinates Unit 6 of NANBIOSIS, has obtained the extraordinary doctoral award from the Universitat Autònoma de Barcelona for her thesis “Nanovesicle-bioactive conjugates to be used as nanomedicines, prepared by a one-step scalable method Using CO₂-expanded solvents“.

This thesis was directed by Jaume Veciana, Scientific Director of NANBIOSIS and Nora Ventosa, Scientific Director of Unit 6 of NANBIOSIS.

The main objectives of the  PhD Thesis of Dr. Ingrid Cabrera were the preparation and study of multifunctional nanovesicle based nanoformulation of alfa-galactosidase for the treatment of Fabry desease as well as of another multifunctional nanovesicle based nanoformulation of epidermal growth factor for the treatment of complex wounds. Both nanoformulations were prepared by a one-step procedure using compressed fluids at U6 of Nanbiosis. This platform also provided many nanoparticles characterization facilities that enabled to obtain important information on the supramolecular organization and characteristics of the produced multifunctional nanovesicles that were key for understanding their biological activities.

Chemical control over the energy-level alignment in a two-terminal junction

In a study published in the journal Nature Communications, researchers of Nanomol group, led by the Scientific Director of Unit 6 of NANBIOSIS, Dr. Jaume Veciana have shown that the alignment of the energy levels in molecular bonds based on sel- assembled monolayers can be regulated through only chemical modifications.

The energy-level alignment of molecular transistors can be controlled by external gating to move molecular orbitals with respect to the Fermi levels of the source and drain electrodes. Two-terminal molecular tunnelling junctions, however, lack a gate electrode and suffer from Fermi-level pinning, making it difficult to control the energy-level alignment of the system. Here is where the researchers report an enhancement of 2 orders of magnitude of the tunnelling current in a two terminal junction via chemical molecular orbital control, changing chemically the molecular component between a stable radical and its non-radical form without altering the supramolecular structure of the junction. These are the findings that demonstrate that the energy-level alignment in self-assembled monolayer-based junctions can be regulated by purely chemical modifications, which seems an attractive alternative to control the electrical properties of two terminal junctions.

Synergies produced in NANBIOSIS multiply the value of its services and allow its users to have results with faster and superior reliability due to proven experience of the scientists and technicians involved, says Jaume Veciana, Scientific Director of NANBIOSIS, in an interview at July 2016 CIBER-BBN Bulletin.

In this interview, Jaume Veciana assesses the functioning of this Singular Scientific-Technical Infrastructure and its contribution to research and anticipates some of the guidelines of the NANBIOSIS Strategic Plan 2017-2020, which includes a clear commitment to internationalization.

“The scientific-technical capabilities available at NANBIOSIS must be exploited without limitation to our country. Therefore we are clear that we must promote the activity of NANBIOSIS both academic and industrial sector in the European Union and other countries, either directly or in association with other similar organizations actions. Some such initiatives have already started but we believe it should be given further boost to internationalization. As an example we can mention the participation in the European project INFRAIA that aims to integrate regional and national research infrastructures existing in Europe under the Horizon 2020”

Professor Veciana also talks about NANOMOL, the research group coordinator of Unit 6 of NANBIOSIS, and the main applications of their findings in the fields of nanomedicine and biomaterials.

Lysosomal storage disorders (LSD) are caused by lysosomal dysfunction usually as a consequence of deficiency of a single enzyme required for the metabolism of macromolecules such as lipids, glycoproteins and mucopolysaccharides. For instance, the lack of alpha-Galactosidase A (GLA) activity in Fabry disease patients causes the accumulation of glycosphingolipids in the vasculature leading to multiple organ pathology.

Enzyme replacement therapy (ERT), which is the most common treatment of LSD, exhibits several drawbacks mainly related to the instability and low efficacy of the exogenously administered therapeutic enzyme. In this work, the unprecedented increased enzymatic activity and intracellular penetration achieved by the association of a human recombinant GLA to nanoliposomes functionalized with RGD peptides is reported. Moreover, these new GLA loaded nanoliposomes lead to a higher efficacy in the reduction of the GLA substrate named globotriasylceramide (Gb3) in a cellular model of Fabry disease, than that achieved by the same concentration of the free enzyme. The preparation of these new liposomal formulations by DELOS-SUSP, based on the Depressurization of a CO2-Expanded Liquid Organic Solution, shows the great potential of this CO2-based methodology for the one-step production of protein-nanoliposome conjugates as bioactive nanomaterials with therapeutic interest.

Recently, the COST Action CA15126 "Between Atom and Cell: Integrating Molecular Biophysics Approaches for Biology and Healthcare (MOBIEU)" has been approved. In this action, the Nanomol Group, coordinator of Unit6 of NANBIOSIS, represented by Imma Ratera has been directly involved being part of the Management Committee.

Molecular-scale biophysics is a dynamic and ever-expanding interdisciplinary field that aims to study biological macromolecules and assemblies as a whole, at an intermediate level between atomic-resolution structural descriptions and cellular-level observations (“Between Atom and Cell”), with significant applications in biomedicine and drug discovery. The MOBIEU Action aims to seed a large-scale pan-European interdisciplinary synergistic clustering, allowing to ally and synergize the power of spectroscopic, hydrodynamic, real-time microfluidic, thermodynamic and single-molecule approaches.

This novel open network will create an optimal environment for the development of innovative integrative biophysical approaches, at the level of data acquisition, analysis and modelling, as well as for the design of unprecedented and ambitious combinations of methodologies, to decipher more efficiently crucial biological phenomena and to overcome significant biomedical challenges.
