Microswimmers use ‘good’ bacteria to target harmful biofilms

A paper by IBEC’s Smart nano-bio-devices group addresses the problem of biofilms, the “microbe cities” that enhance cell-to-cell communication for bacteria, allowing infection to thrive and increasing the chances of evading the immune system. In the body, they can be found in a wide variety of microbial infections, such as in the lungs of cystic fibrosis or chronic obstructive pulmonary disease patients.

Biofilm colonies are usually resistant to antibiotics and require targeted methods of removal. One method uses nanoparticles as carriers for antibiotic delivery, where they randomly circulate in fluid until they make contact with the infected areas. These are not very effective, however, as they need to be able to get much closer to the biofilm.

Visit of DGR staff to the PCB

This morning, about 35 members of staff from the Generalitat’s Direcció General de Recerca (DGR) came to the PCB to visit IBEC and the IRB, the two CERCA centres located there.

Director General of Research Francesc Subirada and Assistant Director General Iolanda Font de Rubinat and their colleagues – who work in finance, HR, IT and other administration roles – carry out visits like this every year to find out what goes on at the organizations that are members of CERCA, the Generalitat’s institution that supervises, supports and facilitates the activities of Catalonia’s research centres. In previous years they’ve also visited the PPRB and ICFO.

The joint program for the morning started with institutional talks by directors Josep Samitier (IBEC) and Joan Guinovart (IRB), pictured above, followed by a coffee break and then a tour of some of the labs and platforms of both the centres.
