We report four experimental strategies for controlling the three-dimensional arrangement of molecules in multicomponent organic crystals, exploiting confocal Raman microspectrometry to quantify the three-dimensional spatial distributions. Specifically, we focus on controlling the distribution of two types of guest molecule in solid organic inclusion compounds to produce composite core-shell cry...

Solubilization of membrane proteins requires surfactants, whose structural properties play a crucial role in determining the protein phase behavior. We show that ionization of a pH-sensitive surfactant, lauryldymethylamino-N-oxide, bound to the bacterial photosynthetic Reaction Center, induces protein phase segregation in micrometric "droplets." Liquid-liquid phase separation takes place in a n...

Cylindrical parts are widely used in industry at very different scales from rotating axis for engines to carbon fibres used in composite materials. Consequently, an increasing demand exists for their nondestructive evaluation. The laser ultrasonics technique providing a non-contact generation and detection process is suited for the study of acoustic waves in cylindrical structures. In previous ...

Retinal vessels are directly accessible to clinical observation. This has numerous potential interests for medical investigations. Using the Retinal Vessel Analyzer, a dedicated eye fundus camera enabling dynamic, video-rate recording of micrometric changes of the diameter of retinal vessels, we developed a semi-automated computer tool that extracts the heart beat rate and pulse amplitude value...

Magnetic field mapping with micrometric spatial resolution and high sensitivity is a challenging application, and the technological solutions are usually based on large area devices integrating discrete magnetic flux guide elements. In this work we demonstrate a high performance hybrid device with improved field sensitivity levels and small footprint, consisting of a ultra-compact 2D design whe...

Recent advances in microfabrication, and the apparent neces-sity of miniaturizing detection and diagnostic systems has led to the emer-gence of a new research field called lab-on-chip, which are mostly workingwith fluids. Liquids actuations at the micrometer scale allow the develop-ment of many new methods based on electric field and potential. Electro-wetting has been widel...
