Abstract Dynamic behaviours of a flame are experimentally examined via applying an electric potential difference between two parallel electrodes and placing a flame of ethanol between them. Given that a flame behaves as a weakly ionised plasma, the shape of the flame is affected by an external strong electric field. When a strong ac electric field is applied horizontally, i.e., transverse field, and as the applied ac voltage increases, the shape of the flame becomes flat and the width of the inner flame expands and saturates at a specific value. When a strong ac electric field is applied vertically, i.e., axial field, the frequency of the self-excited oscillation is affected by a specific value of the applied frequency. When the frequency of the applied ac voltage changes, temperature and light emission of flame are significantly affected by the applied ac voltage. Furthermore, when the strength of the horizontally applied electric field is further increased, a discharge occurs in the flame, and it is reshaped into an arc plasma. The current signals exhibit background troughs and sudden peaks in the form of spikes. The spectrophotometric curve includes the spectra of both the flames and arc plasma under the arc discharge.

This paper reports on the characterization of an integrated micro-fluidic platform for controlled electrical lysis of biological cells and subsequent extraction of intracellular biomolecules. The proposed methodology is capable of high throughput electrical cell lysis facilitated by nano-composite coated electrodes. The nano-composites are synthesized using Carbon Nanotube and ZnO nanorod dispersion in polymer. Bacterial cells are used to demonstrate the lysis performance of these nanocomposite electrodes. Investigation of electrical lysis in the microchannel is carried out under different parameters, one with continuous DC application and the other under DC biased AC electric field. Lysis in DC field is dependent on optimal field strength and governed by the cell type. By introducing the AC electrical field, the electrokinetics is controlled to prevent cell clogging in the micro-channel and ensure uniform cell dispersion and lysis. Lysis mechanism is analyzed with time-resolved fluorescence imaging which reveal the time scale of electrical lysis and explain the dynamic behavior of GFP-expressing E. coli cells under the electric field induced by nanocomposite electrodes. The DNA and protein samples extracted after lysis are compared with those obtained from a conventional chemical lysis method by using a UV–Visible spectroscopy and fluorimetry. The paper also focuses on the mechanistic understanding of the nano-composite coating material and the film thickness on the leakage charge densities which lead to differential lysis efficiency.
