We are thrilled that the Catalan channel, TV3, has highlighted our experiment to visualize full human endothelial cells labeled with iron oxide nanoparticles carried out at the synchrotron ALBA.
Laura has joined the group to pursue a PhD in nanomedicine under the supervision of Anna Laromaine and Anna Roig. She has been granted a FPU scholarship thanks to an excellent academic record. Laura obtained a degree in Pharmacy from the Universitat de Barcelona in July 2012.
Elena is a former group member that has just initiated a professional career in a private sector with a young high-tech company. Prior to that, she will spend a two month visiting internship in our group. Very nice to have you back!
The meeting took place in Bordeaux on the 2nd and 3rd of April 2013. It was the first opportunity that the participants could exchange information on their competences and running projects.
Anna Laromaine, member of our group, is one of the founders of OsmoBlue. This start- up company based in Lausanne is one of the winners of the Fondo de Emprendedores de la Fundación Repsol 2012. Fondo de Emprendedores helps economically and provides mentorship to young companies in energy efficiency topics. This week the Prince of Asturias joined and congratulated all the winners in Madrid.
Maria is a biochemist that obtained a Phd in Biochemistry and Molecular Biology at the UAB. She joints us to be our expert in cell culture studies. She will work in several group projects but very directly in the European Commission funded project “Interactions in Three-dimensional (3D) in vitro environments of Nanoparticles and Cells” lead by Anna Laromaine.
The conference was held in Sorrento, Italy, from 3rd to 7th March 2013. Each day started will a Plenary Lecture followed by 3 parallel symposia:
Symposium A: Biohybrids and biomaterials; Symposium B: Functional hybrid nanomaterials, nanocomposites and their applications; Symposium C: Functional porous materials.
Plenary speakers:
Takuzo Aida, University of Tokyo, Tokyo, Japan C. Jeffrey Brinker, University of New Mexico and Sandia National Laboratories, Albuquerque, NM, USAPeter Fratzl, Max-Planck-Institut für Kolloid- und Grenzflächenforschung (MPIKG), Gölm, Germany Clément Sanchez, Collège de France, Paris, France Sir Fraser Stoddart, Nortwestern University, Evanston, IL, USA
Researchers from the VHIR and our group obtained first images of human endothelial progenitor cells by Transmission Soft X-ray Microscopy at ALBA Synchrotron.
The experiment, performed at the MISTRAL beamline leaded by Dr. Eva Pereiro, allowed us to image whole Endothelial Progenitor Cells (EPC) containing iron oxide nanoparticles by perfoming X-ray cryo-tomography.
The experiment was undertaken by Estela Serra, Anna Laromaine and Anna Roig from our group and Anna Rosell from the Neurovascular Research Laboratory, Institut de Recerca Hospital Vall d’Hebron (VHIR).
Anna delivered an invited talk on Magnetized endothelial progenitor cells (EPC) as angiogenic activators in the Colloidal Nanoparticles for Biomedical Applications VIII Symposium chaired by Prof. Wolfang Parak in San Francisco (2–7 Feb) during the 2013 BIOS – SPIE Photonic West conference.
A Nanoscale paper on “Ultrafast continuous synthesis of crystalline ferrite nanoparticles in supercritical ethanol” (Oana Pascu, Samuel Marre,Cyril Aymonier and Anna Roig) has recently been published. It is the result from the collaboration with the group of Cyril Aymonier from the ICMB-CNRS in Bordeaux, where Oana Pascu spent an internship during her Ph.D. and now she holds a post-doctoral contract.
Magnetic nanoparticles (NPs) are of increasing interest in various industrially relevant products. For these, the development of greener and faster approaches facilitating scaling-up production is of paramount importance. Here, we report a novel, green and potentially scalable approach for the continuous and ultrafast (90 s) synthesis of superparamagnetic ferrite NPs (MnFe2O4, Fe3O4) in supercritical ethanol (scEtOH) at a fairly moderate temperature (260 °C). ScEtOH exhibits numerous advantages such as its production from bio-resources, its lack of toxicity and its relatively low supercritical coordinates (pc = 6.39 MPa and Tc = 243 °C), being therefore appropriate for the development of sustainable technologies. The present study is completed by the investigation of both in situ and ex situ NP surface functionalization. The as-obtainednanoparticles present good crystallinity, sizes below 8 nm, superparamagnetic behavior at room temperature and high saturation magnetization. Moreover, depending on the capping strategy, the ferrite NPs present extended (for in situ coated NPs) or short-term (for ex situ coated NPs) colloidal stability.
