Electroporation apparatus and method
An electroporation apparatus has an electroporation probe terminals for linking with electrodes. A foam is injected at the treatment site to displace blood rather than mixing with it, increasing the contact time of a higher concentration of active agent with the tissue and thus resulting in greater efficacy. With foam solutions, a lower concentration of agent can be used to obtain the same therapeutic effect as in their liquid counterpart, reducing the prevalence of side effects associated with higher concentrations. A foam solution compared to an equivalent liquid solution enables more efficient cell electroporation particularly where bipolar pulses have been employed by mitigating an increase in tissue conductivity as would normally be observed with a comparable liquid solution. A more efficient cell permeabilisation would result in better results where electroporation is being delivered alone or as a tool to aid in the uptake of molecules into the cell. |

Self-sintering conductive inks
Self-sintering conductive inks can be printed and self-sintered with a simple and low-cost process mechanized by exothermic alkali metal and water reaction, with enhanced electrical and thermal performance by liquid metal fusion. Such self-sintering conductive inks may include a gallium-alkali metal component and a water absorbing gel component. After patterning, the self-sintering inks, on reaching a designed trigger temperature (including room temperature), may metallize through a two-step process. Initially the gallium-alkali metal component activates and reacts with water released from the water absorbing gel component. Then the exothermic reaction between the water and the alkali element creates an intense and highly localized heating effect, which liquefies all metallic components in the ink and, on cooling, creates a solid metal trace or interconnect. Post cooling, the metal trace or interconnect cannot be reflowed without a significant temperature increase or other energetic input. |
