Controlling the speed of enzyme motors brings biomedical applications of nanorobots closer
A study by scientists at the Centro Nacional de Investigaciones Cardiovasculares (CNIC), the Universidad Complutense (UCM), Universidad de Girona (UdG), and the Institute for Bioengineering of Catalonia (IBEC), working together with other international centers, has overcome one of the key hurdles to the use of nanorobots powered by enzymes called lipases.
LipoBots: robust nanomotors for biomedical applications developed with encapsulation technology
Researchers at the Institute for Bioengineering of Catalonia (IBEC) and the Catalan Institute of Nanoscience and Nanotechnology (ICN2) have developed a new type of encapsulated enzyme nanomotors.
The called LipoBots, which could be used for medical applications. LipoBots are capable to self-propulsate and to retain their enzymatic functionality in conditions similar to those of the human stomach.
Range selectivity, a new concept that could lead to more efficient nanoparticle drug delivery
In a new study published in the scientific journal Nature Communications, researchers describe a new concept called “range selectivity”, explaining why biomimetic nanoparticles only bind to receptors when their density is within a precise range.
This finding could pave the way for the development of highly targeted therapies against a number of diseases.
New method could help to find the best treatment for a pediatric cancer
A study led by IBEC researchers from the Nanobioengineering group, uses a functional predictive biomarker to anticipate the effect of treatments against rhabdomyosarcoma, the most common soft-tissue cancer affecting childhood and adolescence.
This advance can help in predicting treatment efficiency thus, avoiding tumor resistance and decreasing undesired secondary effects.
3D printed hydrogels for cancer immunotherapy T-cell growth
The new 3D hydrogels provide high rates of cell proliferation, as they mimic lymph nodes, where T-cells reproduce in vivo. A new project, led by researchers from ICMAB and IBEC, and with the collaboration of VHIO and UIC, wants to transfer this technology to hospitals.
Cancer immunotherapy is based on using and strengthening the patient’s own immune system to recognize and fight tumor cells, without damaging healthy tissues.
Nanoscale cellular adhesion is a key factor for cartilage production in vitro
Researchers from the Institute of Bioengineering of Catalonia (IBEC) develop a methodology based on nanopatterned structures which improves the differentiation of mesenchymal stem cells into cartilage in vitro. This advance might be applied to cartilage regeneration techniques aiming to treat lesions.
Lights, Cells, Action! IBEC develops small molecules able to control endocytosis with light
IBEC’s research group “Nanoprobes and nanoswitches” creates a system based on light to inhibit the endocytocis and control its spatio-temporal dynamics. The newly developed light-sensitive small-molecule inhibitors of endocytosis (called dynazos) are water-soluble, cell permeable, photostable, and enable fast photoswitchable inhibition of endocytosis. This technology will allow more accurate and controlled studies were endocytosis is crucial, as in cellular grow, differentiation and motility.
A new method confirms the impact of COVID-19 confinement measures on mental health and well-being
Researchers from the SPECS lab at IBEC develop a new method to evaluate the mental health and wellbeing of people living under strict confinement measures such those during COVID-19 pandemic on April 2020. The study, conducted with people living in 17 countries, confirms that confinement measurements leads to a negative impact on the emotional wellbeing. The researchers also detected some personal situations that can entail a higher risk for the mental health and wellbeing.
Nanotechnology to improve human tissue growth in the laboratory
Researchers from the Institute for Bioengineering of Catalonia (IBEC) have developed an innovative scaffold that allows muscle tissues growth at the millimetre scale in the laboratory.
This technology opens the door to potential applications in fields such as organ transplantation and engineering, drug screening and disease modelling.
