Treatment of mammalian cells with dilute silicic acid followed by heating forms silica replicas of the cell template, offering a way to preserve cell specimens and generate biocomposites for various applications.
Nanoparticles in contact with the biological environment adsorb a layer of biomolecules, which forms the biological identity of the particles. This Review outlines the concepts of the nanoparticle corona and how it interacts with biological systems, and assesses the critical problems to be resolved.
Mechanical metamaterials that have liquid-like properties when taken out of water and solid-like properties when in water can be prepared from DNA hydrogels.
Magnetic circular dichroism reveals an enhancement of paramagnetism in copper-doped ZnSe–CdSe nanoscrystals and that the enhancement persists for hours in the dark.
