NANBIOSIS lecturers in B-Debate Imaging for Life. From Molecules to Diagnostics and Therapy

Last November took place in CosmoCaixa, Barcelona, the B-Debate Days Imaging for Life. Molecules from Diagnostics and Therapy.

The event, organized by B·Debate (an initiative of Biocat and “la Caixa” Foundation), IBB and LJS, was focussed on Biomolecular Imaging, with emphasis on molecular, cellular, tissular and small animal research, as well as biomedical applications, including noninvasive diagnostics, image guided surgery, multimodal imaging and theranostics.

Scientists of NANBIOIS Unit 20 and 25 were invited to participate as guest lecturers:

-Simó Schwartz, Scientific Director of Unit 20: New bioluminescent models to target cancer stem cells with nanomedicine.

-Ana Paula Candiota, Scientific Coordinator of Unit 25: Unravelling therapy response in preclinical glioblastoma using MRSI-based molecular imaging and source analysis.

As Professor Candiota explained “Characterization of Glioblastoma (GB) response to treatment is a key factor for improving patient survival and prognosis. Magnetic Resonance Imaging and Spectroscopic Imaging (MRI/MRSI) provide morphologic and metabolic profiles of GB but usually fail to produce unequivocal surrogate biomarkers of response. Ideally, we would like to provide clinicians with early therapy response follow-up and an improved time frame for changing or adapting therapy schemes”. Her talk focussed in the capability of advanced pattern recognition techniques, such as semi-supervised signal source extraction, to produce nosological images with robust recognition of response to temozolomide (TMZ) in preclinical GB (GL261 tumour-bearing in immunocompetent C57BL/6 mice) through the information contained in MRSI grids. These techniques have a clear translational potential and could improve future patient management and care. The acquisition of mice MRSI data used for pattern recognition strategies development and evaluation was performed in the Biospec 7T scanner from U25.

Laura Lechuga received the Physics, Innovation and Technology Prize

On December 14th, the Physics Awards ceremony was held at the BBVA Foundation’s headquarters, organized by the Spanish Royal Society of Physics (RSEF) and the BBVA Foundation, that each year select the most relevant achievements of Spanish physics. On this occasion the achievements of nanoscience have been recognized and it has been highlighted the power of physics to expand the territory of the known universe and the role of scientists as a core element of social progress.

Professor Laura Lechuga, Scientific Director of Unit 4 of NANBIOSIS received the Physics, Innovation and Technology Prize was the only woman awarded.

Lechuga is a pioneer in Spain in the development of biosensors, devices that integrate in very little volume the analytical capacity of a laboratory, so they have the theoretical potential to revolutionize many technological areas that have a direct impact on society, from medical diagnosis to control of contaminants in the environment. The award winner works on two prototypes of nanophotonic biosensors to detect colon cancer and tuberculosis: “The future of immediate diagnosis goes through such devices, low cost and very high sensitivity, installed in mobile phones, which could be easily used also in regions in development” says professor Lechuga.

Biomedical materials that repel bacteria

The magazine Viceversa dedicates a special article to María Luisa González, Professor of Applied Physics at the University of Extremadura and Scientific Director of Unit 16 of NANBIOSIS: Surface Characterization and Calorimetry Unit.

One of her latest projects, PHYTECH, has developed a new surface for bone implants containing phytate, a natural product found in plant seeds that favours the regeneration of bone tissue and reduces the risk of infections in implants. Now, her research group is about to start a new European project with implant manufacturers in Austria and Lithuania, whose goal is to obtain a crystalline coating for titanium prostheses that favours cell adhesion and prevents or reduces bacterial infections.

The research trajectory of Professor González has a clear vocation towards the transfer of results to society. Her driving force in research is to improve the well-being of patients, improve the quality of materials to reduce infection problems after prosthetic and implant surgery, and also help to reduce the cost of healthcare.

Her challenge for the next five years is to know better the electrical characteristics of surfaces and how its roughness affect, at nanometer level, to prevent bacteria from adhering to them, without harming human cells.

Lipid-based Nanovesicles for Nanomedicine

Jaume Veciana and Nora Ventosa, Scientific Directors of Unit 6 of NANBIOSIS together with other researchers from NANOMOL group, coordinator of Unit 6 of NANBIOSIS, has recently published an interesting review article in the journal Chemical Society Reviews.

This review presents the large plethora of lipid-based nanovescicles available nowadays, focusing on a new generation of non-liposomal L-NVs and showing their similarities and differences with respect to their ancestors (liposomes). Since the overspread of a nanomaterial to the market is also strongly dependent on the availability of technological-scale preparation methods, it also extensively review the current approaches exploited for L-NV production. The most cutting-edge approaches for their preparation based on compressed fluid (CF) technologies is highlighted since they show the potential to represent a game-change in the production of L-NVs, favoring their step from the bench to the market. Finally, this review briefly discusses L-NV applications in nanomedicine looking also for their future perspectives.

From Chromonic Self-Assembly to Hollow Carbon Nanofibers: Efficient Materials in Supercapacitor and Vapor-Sensing Applications

Conxita Solans, Scientific Director of the Unit 12 NANBIOSIS is co-author of the research article recently published a research article in the journal Applied Materials & Interfaces.

Carbon nanofibers (CNFs) with high surface area (820 m²/g) have been successfully prepared by a nanocasting approach using silica nanofibers obtained from chromonic liquid crystals as a template. CNFs with randomly oriented graphitic layers show outstanding electrochemical supercapacitance performance, exhibiting a specific capacitance of 327 F/g at a scan rate of 5 mV/s with a long life-cycling capability. Approximately 95% capacitance retention is observed after 1000 charge–discharge cycles. Furthermore, about 80% of capacitance is retained at higher scan rates (up to 500 mV/s) and current densities (from 1 to 10 A/g). The high capacitance of CNFs comes from their porous structure, high pore volume, and electrolyte-accessible high surface area. CNFs with ordered graphitic layers were also obtained upon heat treatment at high temperatures (>1500 °C). Although it is expected that these graphitic CNFs have increased electrical conductivity, in the present case, they exhibited lower capacitance values due to a loss in surface area during thermal treatment. High-surface-area CNFs can be used in sensing applications; in particular, they showed selective differential adsorption of volatile organic compounds such as pyridine and toluene. This behavior is attributed to the free diffusion of these volatile aromatic molecules into the pores of CNFs accompanied by interactions with sp² carbon structures and other chemical groups on the surface of the fibers.
