Abstract: A method and system for electroporation of a biological cell in a fluidic channel is provided. The method includes: introducing a fluidic flow in a first direction in the fluidic channel wherein the fluidic flow comprises the cell; applying a first electrical field to the cell in the fluidic flow to produce a first electroporation at a first position in the fluidic channel; measuring an impedance of the cell in the fluidic flow at a second position in the fluidic channel; determining a second electrical field depending on the impedance measurement of the cell in the fluidic flow at the second position in the fluidic channel; and applying the second electrical field to the cell in the fluidic flow to produce a second electroporation at a third position in the fluidic channel, wherein the first, second and third positions are sequentially arranged in the first direction of the fluidic flow.

Abstract: The present invention relates to a method for writing data comprising a sequence of bits, the data being written in a form of nucleic acid, by in-vitro enzymatically producing memory nucleic acid from a strand of memory writing substrate nucleic acid, wherein the strand of memory writing substrate nucleic acid comprises a plurality of spacer sections and memory writing sections sandwiched between the spacer sections. Each of the spacer sections comprises one or more nucleobases, and each of the memory writing sections comprises a nucleobase other than the nucleobases of an adjacent spacer section upstream of the memory writing section in a travel direction of an enzyme along the strand of memory writing substrate nucleic acid.

Abstract: A method for writing data including a sequence of bits, the data being written in a form of DNA, by in-vitro enzymatically producing memory DNA from a strand of memory writing substrate DNA is disclosed. In one aspect, the method includes repeating of: receiving a sub-sequence of the sequence of bits, the sub-sequence including at least one bit; selecting memory nucleotides based on the sub-sequence; contacting, in liquid medium including the strand of memory writing substrate DNA contacted with an enzyme, the selected memory nucleotides and the enzyme; and synthesizing a portion of the memory DNA from a portion of the strand of memory writing substrate DNA by the enzyme and at least one of the memory nucleotides of the solution, thereby producing memory DNA including memory nucleotides corresponding to bits of the sequence of bits. The disclosed technology further relates to a micro-fluidic system including a microfluidic chip and a controller.

Abstract: An electrode unit for performing electroporation of a biological cell is provided, including at least one electrode which can contact a cell. A stimulation unit and an impedance measurement device are connected to the cell, respectively to provide signals to provide cell electroporation and to measure the impedance of the electrode in contact with the cell. Further, a memory stores a predetermined value of an impedance parameter of the biological cell, and it is arranged to be readable by a comparing element. The comparing element is configured to compare the value stored in the memory with a value measured with the impedance measurement device, and to produce an adjustment signal to the stimulation unit, forming a feedback loop. The unit is further configured to apply a further electrical signal for providing electroporation of the cell upon receiving the adjustment signal from the comparing element.
