An electroporation system may include a well plate, a dispenser and a dispenser-well positioning system. The well plate may include wells, each of the wells including an interior, a first electrode adjacent the interior and a second electrode adjacent the interior and spaced from the first electrode. The first electrode and the second electrode are to apply an electrostatic field across the well. The dispenser is to dispense a cell having a diameter into each of the wells. The dispenser-well positioning system is to align each well and the dispenser such that the dispenser dispenses the cell into each well at a location spaced from the first electrode and the second electrode by a distance of at least 5 times the diameter of the cell.

Anaerobic digestion is enhanced based on the coupling of electron transfer with microbial electrolytic cell. A traditional anaerobic digestion reactor is used as the main body, a microbial electrolytic cell applied with a micro voltage is constructed, and the electron transfer in the system is optimized by an immobilized conductor material, to establish an efficient electron output-transfer-consumption anaerobic digestion pathway to produce methane.

The present disclosure relates to a biocompatible, in vitro probe system. The probe system may have a substrate and a culture well supported on the substrate. The culture well defines a three-dimensional volume for containing in vitro cultures of electroactive cells. The probe system has at least one probe subsystem supported on the substrate. The probe subsystem has at least one probe having an array of electrodes, with the probe being disposed within the culture well for in vitro electrically communicating with the electroactive cells. The probe subsystem is adapted to be interfaced to an external instrumentation/recording device.

Dynamic polymer surfaces are provided that include alternating micropatterns of adhesive domains and environmental stimuli-responsive repulsive domains, where application of a select environmental stimulus activates polymer structures of the repulsive domains to change conformation with respect to the adhesive domains. The dynamic polymer surfaces are useful for sorting, screening, and enriching target particles (such as cells) in a sample and for culturing and harvesting cells. Products, such as cell culture systems, including the dynamic polymer surfaces are also provided.

A continuous automated perfusion culture analysis system (CAPCAS) comprises one or more fluidic systems configured to operate large numbers of biodevices in parallel. Each fluidic system comprises an input reservoir plate for receiving media; a biodevice plate comprising an array of biodevices fluidically coupled to the input reservoir plate, configured such that each biodevice has independent media delivery, fluid removal, stirring, and gas control, and each biodevice is capable of continuously receiving the media from the input reservoir plate; and an output plate fluidically coupled to the biodevice plate for real-time analysis and sampling. The operations of the CAPCAS are automated and computer-controlled wirelessly. The CAPCAS can also be used for abiotic and biotic chemical synthesis processes.

The present invention provides a system and a method for measuring an impedance of one or more target cells before and after an electroporation protocol has been applied to the one or more target cells. A result of the impedance measurement provides a feedback control that can be implemented during and/or after the electroporation protocol to customize an electrical treatment for a particular target cell or cellular tissue.

The producing method according to the disclosed technology is a producing method for an organism-derived material into which a bioactive substance has been introduced, the producing method comprising a step of causing a suspension containing the organism-derived material before the introduction of the bioactive substance and containing the bioactive substance to pass through a first electric field region having a first electric field intensity; and a step of causing the suspension to pass through a second electric field region having a second electric field intensity lower than the first electric field intensity after the suspension has passed through the first electric field region. The organism-derived material is a human-derived cell.
