What happens to nanoparticles when they enter the bloodstream?

The use of nanoparticles in drug delivery offers key advantages: they can enable targeted drug delivery, protect active ingredients from premature degradation, extend their duration of action in the body and reduce side effects. ...

Nanowires restore key functions in aging T cells

For decades, scientists have accepted that the immune system naturally weakens with age. Georgia Tech biomedical engineer and Carl Ring Family Professor Ankur Singh wasn't convinced. Then the COVID-19 pandemic made the stakes ...

Social amoebae form nanotube networks linking multiple cells

Social amoebae are unicellular organisms that act in concert, requiring extensive communication. Pierre Stallforth and colleagues studied modes of communication among cells of the social amoeba Dictyostelium discoideum, using ...
