FUNCATH: Prevention of infectious diseases with functionalized catheters awarded by La Marató de TV3

FUNCATH project,  coordinated by scientists of NANOMOL  group, led by Dr. Imma Ratera, has been awarded by Fundació La Marató de TV3 .

NANOMOL is the research group that coordinates NANBIOSIS U6 Biomaterial Processing and Nanostructuring Unit, from ICMAB-CSIC and CIBER-BBN.

Fundació La Marató de TV3 2017 call was dedicated to infectious diseases and awarded 36 projects among the 186 evaluated according to their excellence, methodology and relevance.

FUNCATH is the project for Prevention of infections related to vascular catheters by functionalizing catheters impregnated with thermically activatable hydrogels with broad spectrum antimicrobial agents, whose ultimate goal is the development of vascular catheters coated with multibiofunctional hydrogels with broad spectrum antimicrobial activity. The hydrogels will have two functions: first act as a 3D matrix that will support the active biomolecules, specifically cationic peptides (PC), with bactericidal activity against most of the bacteria involved in nosocomial infections and second will act as a protection against the degradation of the PCs until the medical device is used. The latter will be possible thanks to the thermosensitive nature of the hydrogel that will only expose the PCs after their contact with body temperature; which will activate the degradation of the hydrogel and allow the release of active biomolecules. Besides Nanomol group the project involves researchers from the Parc Taulí Hospital, the Hospital Clínic, and the IRTA. The project financing: € 375,078.75 for three years.

Nanoparticles characterization techniques of NANBIOSIS unit 6

The Unit 6 of NANBIOSIS, Biomaterial Processing and Nanostructuring Unit, has organized during the days 8 to 11 of October in the ICMAB-CSIC a course of characterization of Nanoparticles showing some of their techniques to the CSIC researchers.

Amable Bernabé, the technician of unit 6 of NANBIOSIS has shown the theory and practice of some methods to characterize nanoparticles and how to handle the necessary equipment.

Specifically, these techniques were:

  • Dynamic Light Scattering (DLS) with Zetasizer Nano ZS (Malvern Instruments)
    • Size distribution
    • Z Potential
  • Nanoparticle Tracking Analysis (NTA) with Nanosight NS300 (Malvern Instruments)
    • Size distribution
    • Particle concentration
    • Fluorescence
  • Light Scattering (LS) with Mastersizer 2000 (Malvern Instruments)
    • Size distribution

being these techniques developed through the equipment of unit 6 of NANBIOSIS among which are:

These techniques are part of the physical-chemical characterization of the cascade characterization service offered by NANBIOSIS and its diffusion will facilitate the access to the NANBIOIS ISCT increasing demand of NANBIOSIS unit 6.

Manuel Souto received UAB PhD Extraordinary Award

Jaume Veciana and Imma Ratera (NANBIOSIS U6 Biomaterial Processing and Nanostructuring Unit) have supervised Manuel Souto’s PhD thesis entitled “Multifunctional Materials based on TTF-PTM dyads: towards new Molecular Switches, Conductors and Rectifiers”.

The School for Doctoral Studies, together with UAB Alumni, organises an event every semester for the award of PhD degrees and PhD special prizes. With 66 PhD programmes, the UAB is one of the leading Catalan universities in the production of theses and generates approximately a third of the doctoral theses that are defended in the Catalan university system each year. The PhD special prizes confer value to theses which have received the qualification of excellence “Cum Laude” and which, having been proposed by the Admissions Committee of each academic programme, stand out for their contribution and advance in the different areas of our University.The prizes are awarded per academic year, in accordance with PhD regulations and with the criteria specified in each PhD programme.

Artificial 3D Culture Systems for T Cell Expansion

Scientists of NANBIOSIS U6. Biomaterial Processing and Nanostructuring Unit, have recently pubished an article  in the ACS Omega  about the design 0f 3D platforms specific for T cell culture to improve the current T cell  expansion systems to introduce new in vitro models and facilitate the broad use of ACT in the clinics.

Adoptive cell therapy, i.e., the extraction, manipulation, and administration of ex vivo generated autologous T cells to patients, is an emerging alternative to regular procedures in cancer treatment. Nevertheless, these personalized treatments require laborious and expensive laboratory procedures that should be alleviated to enable their incorporation into the clinics. With the objective to improve the ex vivo expansion of large amount of specific T cells, we propose the use of three-dimensional (3D) structures during their activation with artificial antigen-presenting cells, thus resembling the natural environment of the secondary lymphoid organs. Thus, the activation, proliferation, and differentiation of T cells have been analyzed when cultured in the presence of two 3D systems, Matrigel and a 3D polystyrene scaffold, showing an increase in cell proliferation compared to standard suspension systems.

Stimuli-Responsive Functionalization Strategies to Spatially and Temporally Control Surface Properties: Michael vs Diels–Alder Type Additions

DOI: 10.1021/acs.jpcb.8b01652

Stimuli-responsive self-assembled monolayers (SAMs) are used to confer switchable physical, chemical, or biological properties to surfaces through the application of external stimuli. To obtain spatially and temporally tunable surfaces, we present microcontact printed SAMs of a hydroquinone molecule that are used as a dynamic interface to immobilize different functional molecules either via Diels–Alder or Michael thiol addition reactions upon the application of a low potential. In spite of the use of such reactions and the potential applicability of the resulting surfaces in different fields ranging from sensing to biomedicine through data storage or cleanup, a direct comparison of the two functionalization strategies on a surface has not yet been performed. Although the Michael thiol addition requires molecules that are commercial or easy to synthesize in comparison with the cyclopentadiene derivatives needed for the Diels–Alder reaction, the latter reaction produces more homogeneous coverages under similar experimental conditions.
