Abstract, Characterization of the in vivo behavior of nanomaterials aims to optimize their design, to determine their biological effects, and to validate their application. The characteristics of the model organism Caenorhabditis elegans (C. elegans) advocate this 1 mm long nematode as an ideal living system for the primary screening of engineered nanoparticles in a standard synthetic laboratory. This review describes some practicalities and advantages of working with C. elegans that will be of interest for chemists and materials scientists who would like to enter the “worm” community, anticipates some drawbacks, and offers relevant examples of nanoparticle assessment by using C. elegans.

Chiral habit selection on nanostructured epitaxial quartz films

Faraday Discussions, DOI: 10.1039/C4FD00266K

Understanding the crystallization of enantiomorphically pure systems can be relevant to diverse fields such as the study of the origins of life or the purification of racemates. Here, we report on polycrystalline epitaxial thin films of quartz on Si substrates displaying two distinct types of chiral habits that never coexist in the same film. We combine Atomic Force Microscopy (AFM) analysis and computer-assisted crystallographic calculations to make a detailed study of these habits of quartz. By estimating the surface energies of the observed crystallites we argue that the films are enantiomorphically pure and we briefly outline a possible mechanism to explain the habit and chiral selection in this system.

Crystallization of hollow mesoporous silica nanoparticles

Complex 3D nacrostructured nanoparticles are transformed from amorphous silica into pure polycrystalline α-quartz using catalytic quantities of alkaline earths as devitrificants. Walls as thin as 10 nm could be crystallized without losing the architecture of the particles. The roles of cation size and the mol% of incorporated devitrificant on crystallization behavior are studied, with Mg2+, Ca2+, Sr2+ and Ba2+ allproducing pure α-quartz under certain conditions.
