Launching the Preliminary Market Consultation Webinar of the TREMIRS Project: Minimally Invasive Robotic Surgical Systems

Cáceres, April 15th, 2021

The CCMIJU, as a beneficiary of the Innovative Public Procurement Program of the Ministerio de Ciencia e Innovación, through the project “Minimally Invasive Robotic Surgery Systems” (TREMIRS), will invest € 7,345,300 in the development of innovative solutions in surgical robotics to improve services provided to the patient, the surgeon’s ergonomics and offer greater benefits to the surgical team, thus achieving an increase in the quality of healthcare.

This ambitious challenge, 80% co-funded by the European Regional Development Fund under the Programa Operativo Plurirregional de España (POPE) 2014-2020 and by the Consejería de Economía, Ciencia y Agenda Digital de la Junta de Extremadura, will last three years and will develop two innovative solutions in the field of surgical robotics, one focused on laparoscopic robotic surgery and the other on microsurgical robotics.

The first solution will facilitate new surgical approaches, provide improvements in surgeon ergonomics, advances in surgical assistance systems, and new portable training tools. The second will implement robotic micro-instruments for soft tissue manipulation and for performing microsurgical techniques such as anastomosis, suturing and ligation on small anatomical structures such as blood vessels, nerves and lymphatic ducts.

The development of both platforms will provide the National Health System and the Extremadura Health Service new equipment that is not currently available on the market and that will improve the quality of patient services and surgical results.

The project is currently in the preliminary market consultation phase as a prior action to the Innovative Public Procurement procedure for the aforementioned solutions. The purpose of this consultation is to obtain information about innovative solutions that respond to the challenges of the project through technologies that exceed the benefits of the existing ones. The results of this consultation will allow us to define the technical and functional specifications of the solutions to be achieved with a subsequent public procurement process.

You can find more information about the project and the preliminary market consultation at the free webinar on April 21, 2021 at 10:00 am.

New organ-on-chip models provide new information for targeted treatments in personalised medicine

Xavi Illa, Gemma Gabriel, Mar Alvarez and Rosa Villa, researchers of NANBIOSIS ICTS U8 Micro– Nano Technology Unit (from CIBER-BBN and the IMB-CNM-CSIC). are co-authors of two reviews that summarise the latest efforts in organ-on-chip technologies to emulate in vitro microfluidic systems. These devices are an opportunity to evolve the fields of biofabrication and sensing technology.

Organ-on-chip (OOC) technology has been an efficient tool in modern research to substitute laboratory mice and simulate tissue and organ-level physiology and function. In particular, these in vitro devices have been extensively applied to model the intestine, enhancing the research community’s knowledge about intestinal physiology and pathophysiology in order to develop targeted therapies for a more precise and personalised treatment of intestinal diseases.

Now, a review published in Biosensors & Bioelectronics signed by researchers of NANBIOSIS ICTS U8 Micro– Nano Technology Unit, collects information about the intestine models and highlights the necessity to integrate sensors into these in vitro models to shine light on the pathological mechanisms of intestinal disorders at their early stage. The detection of a disease at its early state would allow more efficient treatments and a better prognosis, reducing costs and enhancing the quality of life of the patients.

Last years’ research has had a significant impact in these complex microfluidic systems, though there is still a long way to go to increase biosensors capacity in their operations.

The potential of the OOC technology is enormous. OOC technology may provide a true precision medicine, allowing the use of the patients’ own cells for performing drugs screening before treating the patient“, -explains Mar Álvarez– “To that end, we believe that the integration of sensors into this platforms is mandatory to understand and evaluate the functioning of the organ in real time, providing information that may be used for in-situ decision making”.

Hydrogel microfluidic platforms to improve the predictive capacities of the in vitro models

Another review article published by theese researchers in Applied Materials & Interfaces tackles the progress made in tissue barrier models, as they have a crucial role in regulating organ homeostasis. Current microfluidic systems do not properly mimic cells’ interaction, so recent developments have included biomaterials, such as hydrogels, to emulate these boundaries between tissues and external environment. A hydrogel acts as a microenvironment of the cell and it permits cell culture.

The hydrogel mimics the real cell microenvironment, providing the mechanical cues needed to reproduce the proper organ physiology and function“, Mar Álvarez adds.

Recent developments in the fields of biofabrication show that hydrogels are able to mimic and change the tissue properties and dynamics, thus enabling an in vivo recreation for its reparation.

Toxicity evaluation on non-target organisms with the collaboration of NANBIOSIS U17 Confocal microscopy

Sara Jiménez-Jiménez, Georgiana Amariei, Karina Boltes, María Ángeles García and María Luisa Marina have recently published an article in the Journal of Chromatography A, ·mentioning the collaboration in the investigation of the ICTS “NANBIOSIS” U17 Confocal Microscopy Service of CIBER-BNN and the University of Alcalá.

The echocytotoxicity of racemic panthenol and dexpanthenol at different concentrations and exposure times in Spirodela polyrhiza has been studied using NANBIOSIS U17 Confocal Microscopy Service

“Panthenol (racemic mixture) and its isomer dexpanthenol have been classified as toxic for the aquatic environment by the European Regulation (EC 1272/2008). These studies are based on the natural emission (autofluorescence) of chlorophyll in different parts of the aquatic plant Spirodela polyrhiza (root, shoot and leaf). The estimation of the IC50 for each one of the compounds concludes different behavior of the compounds in the different parts of the plant, showing a higher toxicity for the racemic mixture panthenol”, explains Isabel Trabado, Technical Coordinator of NANBIOSIS U17
