The optical properties of 3D metacrystals made gold nanoparticles in protein nanocages are studied. These have sizes tens micrometers and high structural quality. Through microspectroscopy measurements model calculations it is demonstrated that the show plasmonic absorption green wavelength range largely transparent red infrared ranges. By using empty as placeholders metacrystal lattice, possib...

The release process of phenol blue from a dibutyrylchitin microsphere, prepared with chitin from a silkworm, into an aqueous solution was kinetically analyzed by single microparticle injection/manipulation and absorption microspectroscopy. The distribution ratio and the release rate of phenol blue in the single microsphere/water system were significantly influenced by the pH of the solution. Th...

Memory effects are a classic feature of disordered materials. With Raman-microspectroscopy we evidence memory effect in the deformation densified soda-lime silicate glasses, and with molecular dynamics simulations identify network reconfigurations it originates from. These results pave way toward better understanding plastic instability, damage, rupture properties iono-covalent glassy

Fourier transform infrared (FTIR) microscopy has shown promise as an analytical tool for detecting changes in cells and tissues, such as those due to viral infection, apoptosis induction or malignancy. In many cases, diagnosis via FTIR microscopy can be undertaken on a timescale shorter than that required for other physical or histological techniques. In this work we have used FTIR microscopy t...
