• This paper proposed a new biolabeling system using ferromagnetic resonance properties of multiple magnetic nanowire types for in-vitro cancer type diagnosis.
• The exterior biofunctionalization that bonds ligands to specific cell types enables multiplexed cell labeling; while the intrinsic FMR properties of MNWs enables the spontaneous identification of multiple labels.
• The feasibility of the proposed biolabeling system is validated by applying the same MNW characterization and identification approach on MNW array measurements.
• The work confirms that distinct FMR signals can be detected in a mixed system of individual nanowire types using through transmission response. To account for low FMR signals and close FMR B-field spacing, a fitting algorithm can be used to validate the presence of the specific material types.
• This proposed biolabeling system has the capability to expand cancer cell detection throughput and reduce processing time; it can also be combined with other labeling methods to enhance the testing range of the current methods.

• The complete investigation of VO2 thin films interaction with extremely high frequency waves, as well as nanoparticles interaction with optical waves was conducted.
• The optical properties of VO2 nanosphere and size effect on these characteristics in insulator and metallic phases were investigated.
• VO2 in the form of nanoparticles and thin films reveals controllable properties. Thus, VO2 is a very proper material to use in sensors at different electromagnetic wave frequencies.
• The VO2 nanoparticles can be suggested as a heat transfer agent for cancer cells ablation or hyperthermia treatment.
• The intrinsic radiation of VO2 film in the 28-32 GHz band in the vicinity of metal-insulator phase transition was observed.

• The diagnosis of lung diseases such as, for example, pneumothorax, requires a continuous tracking of their air/liquid content. This latter influences the conductivity value of the chest and it can be inferred in real-time by solving the EIT inverse problem through LBE methodologies.
• The conclusion in this manuscript is that, thanks to the numerical and comparative assessment, it is possible to state the LBE technique at hand yields instantaneous and robust conductivity predictions starting from a low size training set.
• The targeted biological and/or medical application is the continuous real-time tracking of the lungs ventilation/status for patients under mechanical ventilation in intensive care units.
• The significance/breakthrough of this work is the numerical assessment of the reliability and the effectiveness of the LBE technique at hand as applied to solve the EIT inverse problem in real-time to faithfully inferring the lungs status.
• The numerical assessment presented in this paper has proven that the LBE method at hand overcomes representative state-of-the-art techniques thanks to the joint exploitation of the noise-filtering capabilities of the PLS and of the adaptive generation/refinement of the training database.

• Using a wideband test setup of well-controlled impedance, both the lower and higher crossover frequencies for dielectrophoresis of a single biological cell was experimentally measured.
• The measured lower crossover frequency was found in general agreement with that calculated by using the Clausius-Mossotti function in conjunction with experimentally extracted cell characteristics such as membrane resistance and capacitance, as well as cytoplasm resistance and capacitance.
• New formulas were derived to evaluate the Clausius-Mossotti function from cell resistances and capacitances, instead of cell permittivity with assumed cell size and shape. The sensitivity of the crossover frequencies on the cell characteristics was analyzed, too.
• The measured higher crossover frequency was found lower than that calculated. The difference can be attributed to the field being highly nonuniform in single-cell dielectrophoresis, especially at higher frequencies. Additionally, with closely spaced electrodes in single-cell dielectrophoresis, adhesive force may have to be considered even for a relatively nonadherent Jurkat cell.
• The result suggests that the classical Clausius-Mossotti function, originally derived from the Maxwell-Wagner mixture model of a cell suspension, may not apply to single-cell dielectrophoresis in a straightforward manner, especially at high frequencies.
