"single tiny pore formed in silicon nitride membrane positioned in flow cell formed on chip, solutions then introduced on membrane's both sides, applying voltage... precipitates grew closing pore under negative voltage, decreasing ionic current/ precipitates dissolve opening pore under positive voltage, increasing ionic current... can act as rectifier, also as memristor with memory effect in relationship between current/ voltage, also to allow biomolecule detection... neuromorphic computing, sensing, controlled chemical reactions"
