Chemists created a gold-catalyzed method to make non-natural amino acids ready for peptide synthesis, expanding drug design options beyond 22 natural types.

A nanomechanical sensor once limited to the lab can now detect ultrafine airborne particles, closing a key gap in pollution monitoring and climate science.

Three cheap hygroscopic salt solutions on carbon nanotube sensors distinguish nine toxic gases, including warfare agents, without engineered receptor molecules.

Oral polysaccharide-engineered nanozyme treats colitis-linked mental disorders by targeting oxidative stress and gut dysbiosis via the microbiome-gut-brain axis.

The nanodevice produces an autonomous, stable current from evaporating saltwater by using heat and light to control the movement of ions and electrons.

Scientists used entangled X-ray photon pairs to produce ghost images of tiny samples, a proof of concept that could enable longer, lower-dose studies of delicate biological materials.
