Method for the selection or processing of first particles sensitive to the application of an external stimulus, comprising the step of producing, by applying said external stimulus, the rupture/lysis of at least one selected first particle, said method comprising the steps of: a) providing an array of electrodes, each electrode having dimensions comparable to or smaller than those of said first particles (CELL) and each electrode being a selectable electrode; b) selectively energizing said array of electrodes to apply to all of said electrodes a first pattern of voltages to generate a first field of force (FMAN) having first points of stable equilibrium (MPEQ) each positioned at a first position, wherein the first particles are attracted towards the first points of stable equilibrium and are situated at the first position; c) applying to all of said electrodes of said array a second pattern of voltages, different from the first pattern of voltages, so as to generate a second field of force (FZAP) having at least one second point of stable equilibrium (ZPEQ) positioned at a second position in a gap between at least two electrodes adjacent to each other and to the at least one selected first particle to be lysed; wherein the at least one selected first particle (CELL) to be lysed is attracted to the at least one second point of stable equilibrium (ZPEQ) and shifted to the second position; and wherein: i) said second field of force (FZAP) applies, only at the second position at which at least one second point of stable equilibrium (ZPEQ) is generated, a stimulus to lyse the at least one selected first particle (CELL) to be lysed and said second field of force (FZAP) being designed such that at least one first particle that is not selected to be lysed remains at the first position; ii) said first pattern of voltages and said second pattern of voltages are applied in a time sequence to the same said electrodes. a) providing an array of electrodes, each electrode having dimensions comparable to or smaller than those of said first particles (CELL) and each electrode being a selectable electrode; b) selectively energizing said array of electrodes to apply to all of said electrodes a first pattern of voltages to generate a first field of force (FMAN) having first points of stable equilibrium (MPEQ) each positioned at a first position, wherein the first particles are attracted towards the first points of stable equilibrium and are situated at the first position; c) applying to all of said electrodes of said array a second pattern of voltages, different from the first pattern of voltages, so as to generate a second field of force (FZAP) having at least one second point of stable equilibrium (ZPEQ) positioned at a second position in a gap between at least two electrodes adjacent to each other and to the at least one selected first particle to be lysed; wherein the at least one selected first particle (CELL) to be lysed is attracted to the at least one second point of stable equilibrium (ZPEQ) and shifted to the second position; and wherein: i) said second field of force (FZAP) applies, only at the second position at which at least one second point of stable equilibrium (ZPEQ) is generated, a stimulus to lyse the at least one selected first particle (CELL) to be lysed and said second field of force (FZAP) being designed such that at least one first particle that is not selected to be lysed remains at the first position; ii) said first pattern of voltages and said second pattern of voltages are applied in a time sequence to the same said electrodes. i) said second field of force (FZAP) applies, only at the second position at which at least one second point of stable equilibrium (ZPEQ) is generated, a stimulus to lyse the at least one selected first particle (CELL) to be lysed and said second field of force (FZAP) being designed such that at least one first particle that is not selected to be lysed remains at the first position; ii) said first pattern of voltages and said second pattern of voltages are applied in a time sequence to the same said electrodes.
