Non-contact mechanical and chemical analysis of single living cells by microspectroscopic techniques

A non-contact method that combines two microspectroscopic techniques can perform mechanical and chemical analysis of single living cells. These properties are intimately connected and assures the correct functionality of cells and tissues: their imbalances can be symptoms and effects of pathologies. Current measurements of cell mechanics require physical contact or they lack in spatial resolution.

A living bio-hybrid system studied by means of a multidisciplinary approach

A multidisciplinary approach to study the functional properties of neuron-like cell models constituting a living bio-hybrid system: SH-SY5Y cells adhering to PANI substrate

One of the more challenging aspects in cognitive or in rehabilitation neurosciences is the design of functional hybrid systems able to mimic the brain functionality, to connect and to exchange information between biological materials, like brain or neurons, and man-made electronic devices.

Interfacial Dzyaloshinskii-Moriya Interaction in Pt/CoFeB Films: Effect of the Heavy-Metal Thickness

Dzyaloshinskii-Moriya interaction (DMI), i.e., the antisymmetric exchange interaction, is the subject of intense research due to its capability to induce the formation of chiral spin textures, such as magnetic Skyrmion lattices and spin spirals. In ultrathin ferromagnetic (FM) films in contact with a nonmagnetic heavy metal (HM), a noticeable interfacial DMI can arise due to the large spin-orbit coupling in the presence of the broken inversion symmetry at the FM/HM interface, leading to an asymmetric spin-wave dispersion.

Snell's law for spin waves

Snell’s law describes the refraction of waves at the transition between two media with different indices of refraction. In optics, the dispersion relation of light is isotropic, and thus, the relation between the incident and refracted angles is solely determined by the ratio of the refractive indices. In contrast, for spin waves in thin films with in-plane magnetization the dispersion relation is inherently anisotropic, and thus, deviations from the Snell’s law in optics are expected but have not been reported directly so far.
