Transparent materials influence the phase evolution of transmitted radiation, however, chromatic dispersion is an issue. Ossiander, M et al.'s article published in Nature Communications experimentally displays the use of ultrathin nanostructured coatings that address this dispersion.

Spectroscopic methods, including Raman spectroscopy, are ideal for the non-invasive imaging of tumors. Spatially resolved versions of the techniques can be used to profile the full tumor site and the spectral information provided at each imaging point can then be decomposed to provide chemical information on the local region.

Raman spectroscopy has become an essential tool for chemists, physicists, and biologists. By analyzing subtle molecular vibration modes, the technique enables high-sensitivity non-invasive structural studies of different water-soluble and membrane-bound biomolecules (DNA, RNA, proteins) and their interactions under physiological conditions.

Being able to measure the exact contributions of amino acids to a given structure or discern the different conformational structures is key to the development of new therapies that make use of these proteins. Recent work from a collaboration between the Eötvös Loránd University, Hungary, KIT University in Karlsruhe, Germany, and Bruker, has involved developing a NMR method that captures these shifting structures for characterization.
