Light-activated nanoparticles trigger copper overload to kill cancer cells
Cuproptosis was discovered in 2022. It was a previously unknown type of cell death caused by an excess of copper. The research group led by Professor Johannes Karges at Ruhr University Bochum, Germany, used this mechanism ...

Express yourself: Scientists use genetic algorithm to design self-assembling ssDNA-grafted particles
(Phys.org) —Material design usually follows what is known as the Edisonian method, a traditional process characterized by trial-and-error discovery rather than a systematic theoretical approach. While this may be somewhat ...
Nano-decoy lures human influenza A virus to its doom
To infect its victims, influenza A heads for the lungs, where it latches onto sialic acid on the surface of cells. So researchers created the perfect decoy: A carefully constructed spherical nanoparticle coated in sialic ...
