Genetically Engineered Nanoparticle Delivers Dexamethasone Directly to Inflamed Lungs
University of California San Diego

Nanoengineers at the University of California San Diego have developed immune cell-mimicking nanoparticles that target inflammation in the lungs and deliver drugs directly where they’re needed. As a proof of concept, the researchers filled the nanoparticles with the drug dexamethasone and administered them to mice with inflamed lung tissue. Inflammation was completely treated in mice given the nanoparticles, at a drug concentration where standard delivery methods did not have any efficacy.

The images leave no one cold: giant vortices of floating plastic trash in the world's oceans with sometimes devastating consequences for their inhabitants – the sobering legacy of our modern lifestyle. Weathering and degradation processes produce countless tiny particles that can now be detected in virtually all ecosystems. But how dangerous are the smallest of them, so-called nanoplastics? Are they a ticking time bomb, as alarming media reports suggest? In the latest issue of the journal Nature Nanotechnology, a team from Empa and ETH Zurich examines the state of current knowledge – or lack thereof – and points out how these important questions should be addressed.
