New chemical lego blocks for health solutions
IBEC researchers develop new multi-responsive molecules able to self-assemble in water forming fiber-like structures. The so-called discotic molecules show responsiveness to temperature, light, pH, and ionic strength and they might show great potential for medical applications such as drug delivery systems, diagnosis or tissue engineering.

Within this group, Edgar and his colleagues focus on the synthesis of novel smart supramolecular materials for drug delivery.
“We have achieved that blind fish recover their vision by adding a light-sensitive molecule to the tank’s water that has a pharmacological effect on their retina, ”explains Pau Gorostiza, ICREA researcher at IBEC, who has been working on the development of light regulated drugs for more than ten years.
Rossella Castagna a postdoctoral researcher in the Nanoprobes and Nanowitches group at IBEC was awared with the ISOP2019 prize last week 9th International Symposium on Photochromism held in Paris. This recognition comes from her contribution to the field of photochromism and for the results that were collectively obtained in their group in the field of photopharmacology.
Scientists from the Institute for Bioengineering of Catalonia develop a technique that enables them to work out the specific function of a neuronal receptor according to its location in the brain. The study, published in PNAS, is based on the activation of photoswitchable drugs with micrometric precision and offers new opportunities in neurobiology.
A scientific team led by IBEC and UAB manages to efficiently activate molecules located inside cell tissues using two-photon excitation of with infrared light lasers. The results of the study has been published in Nature Communications.
Collaborating IBEC groups have published a study in Nature Communications that reveals that electron transfer can take place while a protein is approaching its partner site, and not only when the proteins are engaged, as was previously thought. 
Researchers at IBEC and IDIBELL have developed a light-regulated molecule that could improve chemotherapy treatments by controlling the activity of anticancer agents.
