Smart-4-Fabry final workshop

Next Wedneday, February 3, 2021 will take place the on-line event Smart-4-Fabry Final Workshop.  

Smart-4-Fabry is a european project, coordinated by CIBER-BBN wich has been developed during four years. This project is a sign of cooperation at European level to boost nanomedicine development and translation to clinical stages.

This project is also a clear example of the relevance of access to advanced research infrastructures as NANBIOSIS -ICTS. Four NANBIOSIS units have collaborated and contributed to Smart-4-Fabry development:

“The Fabry disease (FD) is a lysosomal storage disorder (LSD) that currently lacks an effective treatment” as Prof. Nora Ventosa, IP of the project, explained for NANBIOSIS blog – The aim of Smart-4-Fabry is to obtain a new nanoformulation of GLA, that will improve the efficacy and toleration compared to the actual treatment with non-formulated GLA.

In the final workshop experts will talk about how, why and for what the solution proposed by Smart4Fabry was conceived.

Two new equipment items at the U6 of Nanbiosis with cofinancing from FEDER funds

The U6 of NANBIOSIS (Biomaterial Processing and Nanostructuring Unit) has expanded its capabilities with 2 new equipment items for the characterization unit. Both equipment items will allow the characterization of some physico-chemical properties of different nanomaterials.

The Zetasizer ULTRA is used to measure the particle size of dispersed systems from sub-nanometer to several micrometers in diameter, using the technique of Dynamic Light Scattering (DLS). Zetasizer systems are also used to analyze particle mobility and charge (Zeta potential) using the technique of Electrophoretic Light Scattering (ELS), and the molecular weight of particles in solution using Static Light Scattering (SLS).

The Green laser module for the NanoSight NS300 equipment. The NS300 allows analysis of the size distribution and concentration of all types of nanoparticles from 0.01 – 1 µm in diameter. This new laser module will allow NTA to measure a range of fluorescent particles, avoiding interferences during the measurements due to sample (auto)fluorescence and absorption.  This is done by detecting the fluorescence signal, which is emitted naturally by particles or as a result of fluorescence labeling or tagging


This equipment have been confinanced by the European Regional Development Fund (ERDF) through the Plurirregional Operational Program of Spain (POPE)2014-2020

Novel Quatsome nanovesicles, prepared using compressed CO2, for the development of advanced nanomedicines

Guillem Vargas Nadal, researcher at Nanomol Group – NANBIOSIS U6 (ICMAB-CSIC and CIBER-BBN) and Nanomol Technologies will defend his PhD thesis on Friday, 23 October 2020, at 11 am in an online session. The PhD Thesis Defense will be held by videoconference from the ICMAB Meeting Room. 

Further information and Registration to attend the PhD Thesis defense via Zoom nanoparticles at ICMAB-website.

Supervisors:

  • Nora Ventosa (Scientific Director of NANBIOSIS U6 Biomaterial Processing and Nanostructuring Unit and leader of Nanomol Group of CIBER-BBN
  • Lidia Ferrer (Nanomol Technologies S.L.)

Abstract: The nanovesicles are being developed and investigated to be used in the pharmaceutical world to deliver drug and detect diseases. However, there are some drawbacks related to the nanovesicles that must be considered, like their stability and their applicability. Concerning that, in this Thesis we have developed a new type of stable nanovesicles called MKC-Quatsomes to be used as intravenous drug delivery systems. Their production, physicochemical characteristics, and stability are strongly related to the dispersant medium. Furthermore, the MKC-Quatsomes were labeled with fluorescent organic dyes, which present FRET phenomenon in order to overcome the drawbacks of the single-dye-loaded nanoparticles.

Impact of Extracellular Vesicle Isolation Methods on Downstream miRNA Analysis in Semen

An article by Sara Larriba of the Human Molecular Genetics Group of Bellvitge Biomedical Research Institute (IDIBELL), recently published by the International Journal of Molecular Science. entitled “Impact of Extracellular Vesicle Isolation Methods on Downstream miRNA Analysis in Semen: A Comparative Study“, acknowledges NANBIOSIS ICTS for its participation in the research results. The nanoparticle tracking analysis was performed by the ICTS NANBIOSIS U6 Biomaterial Processing and Nanostructuring Unit.

Abstract:

Seminal plasma (SP) contains a unique concentration of miRNA, mostly contained in small extracellular vesicles (sEVs) such as exosomes, some of which could be clinically useful for diagnosis and/or prognosis of urogenital diseases such as prostate cancer (PCa). We optimized several exosome-EV isolation technologies for their use in semen, evaluating EV purifying effectiveness and impact on the downstream analysis of miRNAs against results from the standard ultracentrifugation (UC) method to implement the use of SP sEV_miRNAs as noninvasive biomarkers for PCa. Our results evidenced that commercial kits designed to isolate exosomes/EVs from blood or urine are mostly applicable to SP, but showed quantitative and qualitative variability between them. ExoGAG 3500× g and the miRCURY Cell/Urine/CSF 1500× g methods resulted as equivalent alternative procedures to UC for isolating exosomes/sEVs from semen for nanoparticle characteristics and quality of RNA contained in vesicles. Additionally, the expression profile of the altered semen sEV-miRNAs in PCa varies depending on the EV isolation method applied. This is possibly due to different extraction techniques yielding different proportions of sEV subtypes. This is evidence that the exosome-EV isolation method has a significant impact on the analysis of the miRNAs contained within, with important consequences for their use as clinical biomarkers. Therefore, miRNA analysis results for EVs cannot be directly extrapolated between different EV isolation methods until clear markers for delineation between microvesicles and exosomes are established. However, EV extraction methodology affects combined models (semen exosome miRNA signatures plus blood Prostate specific antigen (PSA) concentration for PCa diagnosis) less; specifically our previously described (miR-142-3p + miR-142-5p + miR-223-3p + PSA) model functions as molecular marker from EVs from any of the three isolation methods, potentially improving the efficiency of PSA PCa diagnosis..

Nanoprobes for the next generation of Optical Imaging

Judit Morlà Folch, CIBER-BBN Researcher in Nanomol Group and NANBIOSIS U6 Biomaterial Processing and Nanostructuring Unit at ICMAB-CSIC is giving the seminar “Nanoprobes for the next generation of Optical Imaging“, today Monday, 5 October 2020 at 12 pm, Hosted by Nora Ventosa, Nanomol Group in the cycle of Online ICMAB PostDoc Talk.

Online Invited Seminar by Zoom. Register here to attend.

About the Seminar: Molecular imaging plays a vital role in the healthcare sector, since abnormal conditions and diseases are often diagnosed through imaging, while therapeutics methods used for the treatment of the abnormalities are often guided by imaging. Optical imaging is a highly sensitive technique and low-cost procedure in comparison to tomography, Magnetic Resonance Imaging (MRI) or ultrasounds among the other forms of imaging currently employed.  Among the imaging agents, fluorescent organic nanoparticles (FONs) are emerging as an attractive alternative to the well-established fluorescent inorganic nanoparticles or small organic dyes. Their proper design allows one to obtain biocompatible probes with superior brightness and high photostability, although usually affected by low colloidal stability

Judit Morlà Folch began her postdoc in 2008 at New Jersey Institute of Technology (NJIT, EEUU) under the Marie Curie Tecniospring and Postdoctoral Programme in collaboration with ICMAB-CSIC (Nanomol Group), where she is nowadays working on the development of fluorescent organic nanoparticles for bioimaging.
