Stimuli-responsive 'cluster bombs' for tumor therapy

Researchers have designed a a pH-responsive size-changeable 'Cluster Bomb' based on mesoporous silica nanoparticle and peptide tLyP-1-modified tungsten disulfide quantum dots programmed tumor therapy.

A breakthrough in 'dead layer' of antiferromagnet

Researchers made a breakthrough to solve the 'dead layer' effect problem in synthetic antiferromagnets.

No amplification needed: Ultrasensitive DNA quantification by light scattering

Traces of biomolecules such as DNA can be detected with a new 'dynamic' technique based on the observation of association and dissociation events of gold nanoparticles. If the desired DNA sequence is present, it can reversibly bind two nanoparticles together.

The glass transition caught in the act

Islands of cooperating atoms jam like ice floes as a liquid becomes like glass.

Harnessing light to drive chemical reactions

A new study shows how a light-harvesting metal transfers energy to a catalytic metal, opening the way for better catalyst designs.

Precision work: defect-free coatings for silicon spheres

Researchers have recently succeeded in homogeneously coating spherical surfaces so that the roughness of the layers remains below a nanometer.
