A nanophenomenon that triggers the bone-repair process

Researchers of the ICN2 Oxide Nanophysics Group led by ICREA Prof. Gustau Catalan have resolved one of the great unknowns in bone remodelling: how the cells responsible for forming new bone tissue are called into action. ...

Macrophage nanosponges could keep sepsis in check

A team of researchers at the University of California San Diego has developed macrophage "nanosponges" that can safely absorb and remove molecules from the bloodstream that are known to trigger sepsis. These macrophage nanosponges, ...

Fewer laboratory animals thanks to secondary nanobodies

Antibodies are indispensable in biological research and medical diagnostics. However, their production is time-consuming, expensive, and requires the use of many animals. Scientists at the Max Planck Institute for Biophysical ...

Designer nanoparticles destroy a broad array of viruses

Viral infections kill millions of people worldwide every year, but currently available antiviral drugs are limited in that they mostly act against one or a small handful of related viruses. A few broad-spectrum drugs that ...
