Order request


Located at the Valld’Hebron Research Institute (VHIR) in Barcelona, U20 In vivo Experimental Platform has three different sections, a Molecular Imaging section for in vivo, ex vivo and in vitro imaging studies (fluorescence, bioluminescence and X-rays), a preclinical animal model section and a preclinical histology section. All three sections are included within the Functional Validation & Preclinical Research (FVPR) of CIBBIM-Nanomedicine.

This unit is led by Dr. Ibane Abasolo (Head of FVPR). Its mission is to offer products and services for the preclinical proof-of-concept validation of therapeutic compounds and biomarkers with potential clinical applications. One of the distinguishing features of this unit is that basic preclinical studies including toxicology, histopathology and efficacy treatments are complemented with non-invasive optical imaging technologies. In vivo bioluminescence and fluorescence imaging allows monitoring of living mice longitudinally, offering real time insight into treatment efficacy, whole-body biodistribution and target mechanisms. Although in Spain there are other institutions with similar equipment, this is the only case in which imaging services can be combined with specifically devoted animal models.

Temperature-sensitive hydrogels: A pioneering therapeutic approach for ovarian cancer

A new project with the participation of NANBIOSIS Unit 20 pioneers thermosensitive hydrogels for localized ovarian cancer treatment, minimizing side effects and enhancing efficacy. May 2024, VHIR/FVPR/CIBER-BBN (Barcelona). As the world recently commemorated Ovarian Cancer Day, from NANBIOSIS we proudly highlight the groundbreaking work of our collaborators in the fight against this deadly disease. Ovarian cancer stands as the seventh leading cause of cancer-related deaths, with Europe bearing the brunt of its impact, recording over 44,000 fatalities annually. In a bid to revolutionize treatment paradigms and enhance patient outcomes, researchers at the Clinical Biochemistry, Drug Delivery and Therapy (CB-DDT) Group,[...]

Reaching for the unreachable: New efforts to treat Lysosomal Storage Diseases

NANBIOSIS researchers pioneer novel treatments for Lysosomal Storage Diseases utilizing extracellular vesicles and liposomes, offering hope to patients. 1 March 2024, Vall d’Hebron Research Institute/ICMAB-CSIC (Barcelona) Lysosomal Storage Diseases (LSDs) encompass a group of rare disorders caused by mutations in lysosomal proteins. These mutations can lead to dysfunctional proteins responsible for breaking down cellular materials, resulting in the accumulation of deposits. Such accumulations can manifest in various neurological symptoms, ranging from progressive neurodegeneration to severe cognitive impairment. Often emerging in childhood, LSDs tragically culminate in premature death for many patients. Currently, up to 14 subtypes of LSDs can be treated[...]

New upcoming events: The active role of NANBIOSIS in awareness of rare diseases

For Rare Disease Day, we raise awareness through 2 events: 1 in Barcelona (Feb 28) & another in Madrid (Feb 29). Collaboration & research in focus. 28-29 February 2024, Rare Disease Day 2024 NANBIOSIS is actively involved in promoting awareness and understanding of rare diseases, Due to their lower incidence, these conditions are often face neglect in medical research and industrial treatment. To spotlight this crucial issue, NANBIOSIS is pleased to announce its participation in two significant events coinciding with Rare Disease Day celebrations. These events will address various aspects of rare and minority diseases research and treatment. Event 1:[...]

Polymeric Micelles Delivering Hope: A Revolutionary Strategy to Fight Cancer

NANBIOSIS researchers reach intracellular targets with encapsulated antibodies. February 2024, IQAC-CSIC/CIBER-BBN, Barcelona (Spain) and Santiago (Chile) Dr. Abasolo and her team have developed an innovative strategy to combat intracellular oncogenes, notably KRAS, implicated in various deadly cancers. By encapsulating therapeutic antibodies within polymeric micelles, they have successfully facilitated the entry of these antibodies into cancer cells, targeting internal markers. This breakthrough, achieved through international collaboration, represents a significant advancement in cancer treatment and holds promise for addressing other diseases with intracellular targets. These findings provide hope for improved therapies and outcomes in cancer and beyond. Every individual is said to[...]

The door is now open to a new nanoparticle-based treatment for chronic liver disease

– It is possible to achieve an administration method that improves the effectiveness and increases the safety of drugs for chronic liver disease? -Yes, with nanoparticles! – How? To find an answer, was created the european project NANOSIM (Biodegradable nanoparticles of Simvastatin as new therapeutic tool for chronic liver disease financed in the Joint Transnational Call (2018) led by the Hospital Vall d´Hebron. A translational research proposed as an approach for its use in patients. Until now, the only therapeutic option for patients is to eliminate the etiological agent (or the external promoter of damage), whether it is a virus,[...]
