The Biosensors for bioengineering group is a junior group under IBEC’s Tenure Track scheme.
Our research is focused on multi tissues organs-on-a-chip (OOC) and more specifically in the metabolic crosstalk within tissues and their relationship with metabolic diseases. Our projects are focused on four key tissues regulating glucose homeostasis, namely, the pancreas, liver, skeletal muscle, and adipose tissue. To achieve this objective, it is necessary a combined interdisciplinary approach.
Biomaterials and tissue engineering research
1) We have several lines of research related with skeletal muscle. Our first approach was with C2C12 mice cell line. We evaluated the influence of mechanical stiffness and geometrical confinement on the 3D culture of myoblast-laden chemically modified gelatin photo-cross linkable composite hydrogels in terms of in vitro myogenesis.
2) Encapsulation of beta-cells like from human skin fibroblast (collaboration with IDIBAPS). This work addresses two critical issues in the design of an efficient beta-cell replacement therapy: an accessible cell source for generation of substitute beta-cells and an adequate delivery device for transplantation. On one hand, we propose to generate transplantable functional insulin-producing beta-cells from fibroblasts through direct reprogramming strategies that bypass the pluripotent iPS stage. On a second objective, we are working in a new system of encapsulating beta-cells like in two steps, microencapsulation to protect cells from immune system and microencapsulation to mechanically protect them and manipulate them.
3) We are developing three-dimensional micro liver models using various biomaterials to recreate the in vivo-like mechanical properties and using hepatocytes and stellate cells. We are collaborating with Grifols company to test some drugs in our model.
4) We have a collaboration project with NovoNordisk to work in new approaches to encapsulate retinal cells.
1) Integrating biosensors in an organ-on-a-chip. We are studying with in situ electrochemical biosensors the release of insulin under the effect of external stimuli, changes in glucose levels and myokines secreted by skeletal muscle (multi-OOC approach).
2) Related with this project we are implementing new biosensors systems. To fully exploit the potential of the organs-on-a-chip, there is a need to interface them to integrated sensing modules, capable to monitor in real-time their biochemical response to external stimuli, like stress or drugs. The goal of this project is to answer this need, by developing a novel technology based on integrating localized surface plasmon resonance (LSPR) sensing module to organs-on-a-chip devices to monitor disease and evaluate drug response in organs-on-a-chip models.
3) Myotonic dystrophy type 1 (DM1) (collaboration with Hospital de la Fe and INCLIVA, Valencia, Spain). We have developed human skeletal muscle micro physiological tissues using micro molding technology and we have integrated them with amperometric biosensors to study the inflammatory process related with electrical and chemical stimuli. We have used transdifferentiated skin fibroblast human cells from DM1 patients and healthy human. Using this platform, we have started to evaluate different treatments, to screen drugs and to evaluate doses.
4) NMR integrated with OOC. The objective of this project is to develop a new technology based on magnetic resonance spectroscopy and imaging using dynamic nuclear polarisation (DNP-MR) integrated with OOC devices to monitor disease and evaluate drug response in OOC models. As a proof-of-concept, this project will fabricate a biomimetic multi OOC integrated device composed of liver spheroids and pancreatic islets and develop the necessary DNP-MR hardware and software to study metabolic diseases and for future drug screening applications. We are working in collaboration with Oxford instrument and Multiwave companies.

Developed by the IBEC, this system is created using patient cells and represents the first 3D muscle model capable of replicating the damage caused by Duchenne muscular dystrophy. The next phase of this project involves the development of an organ-on-a-chip platform, enabling more efficient preclinical studies of potential drugs and enhanced monitoring of muscle damage. Funding for this research has been provided by Duchenne Parent Project Spain, a non-profit association led by families with children affected by this form of dystrophy.

Researchers from the Institute for Bioengineering of Catalonia (IBEC) led by ICREA Research Professor Javier Ramón, appear in the media for a recent study in collaboration with IDIBAPS researchers, in which they have developed small spheres capable of responding to variations in the levels glucose and produce insulin in vitro.
Researchers from IBEC, in collaboration with IDIBAPS in Barcelona, have developed nontoxic small spheres able to respond to variations in glucose levels, and producing insulin in vitro. These biomimetic spheroids containing pancreatic β-cells were prepared based on 3D bioprinting. This approach might help in the future improving clinical outcomes of β-cell transplantation strategies for diabetes treatment, as well as for in vitro drug screening platforms.
International experts and three hundred registered attendees met in the 14th IBEC Symposium, dedicated to regenerative therapies. Organised by the Institute for Bioengineering of Catalonia (IBEC), speakers presented the latest advances in mini-organs, organs on a chip, 3D bioprinting and tissue engineering, among others.
In a recent publication in the journal Nanophotonics, IBEC researchers present a new biosensor for the direct and sensitive detection of the protein interleukin-6 in muscle, an indicator of inflammation and potential disease, proving the high performance of the device on bioengineered 3D skeletal muscles. This new approach may result in a promising tool for measuring the efficacy of drug candidates for diseases where inflammation is present such as muscular dystrophy.
IBEC researchers led by Javier Ramón and Juan M. Fernández develop the first three-dimensional model for myotonic dystrophy, a rare disease that currently has no cure. The model combines patient cells and bioengineering techniques and represents a major advance over the use of animals and cell cultures. This new model will help in the design of personalized and more effective treatments, and for drug testing in a much more efficient way.
