Does the matrix electrode have using age limited?
Yes, it does have using age limited. Since the matrix electrode is made of biocompatible stainless steel materials, which has been removed non-biocompatible ions such as manganese, chromium and nickel. There would be appear the surface oxidation or other electrochemical phenomena around the electrode needles after a certain number of electroporation. There phenomena may reduce the transfection efficiency of electroporation. So that, when the matrix electrode is reused about 100 times, changing a new matrix electrode is suggested.
