    • The present invention has an object of providing a method by which two kinds or more of molecules can be separated each other by using dielectrophoretic forces. The present invention comprises two methods. The first method is a method comprising forming a complex substance of a "specific molecule" containing in a sample, and a "substance capable of changing dielectrophoretic properties of the specific molecule", which binds to the "specific molecule" contained therein, and thereby separating the complex substance and the molecules other than the specific molecule in the sample from each other. The second method is a method comprising placing a solution in which two kinds or more of molecules are dissolved under a strong electric field strength, that is, under a nonuniform electric field having an electric field strength of 500 KV/m or higher, by using dielectrophoretic forces.

    • A main magnetic pole core (2) of a metallic soft magnetic multi-layer film is formed on a substrate (100) via a non-magnetic insulation film (1a), two detecting conductor films (3a,3b) are making contact with both side faces of the main magnetic pole core respectively, and a high-frequency signal is applied across the two detecting conductor films. When a magnetic flux passing through the main magnetic pole core (2) changes, its impedance changes, and this change is taken out as the change in the amplitude of the high-frequency signal. A pair of electrode terminals (5a,5b) connected to both ends of the detecting conductor films (3a,3b) respectively, a power source terminal and a ground terminal (4a and 4b, respectively) are formed on the substrate. A semiconductor bare chip (127) used as a high-frequency amplifier is installed so as to be opposite to these terminals, whereby the terminals of the bare chip are directly connected to the electrode terminals, power source terminal and ground terminal.
    • 主磁极芯(2)的金属软磁性多层膜是通过非磁性绝缘膜(1a)中,两个检测导体膜的基板(100)上形成(3A,3B)正在接触这两个 主磁极芯分别的侧面上,并且高频信号被跨越两个检测导体膜的应用。 当磁通量穿过主磁极芯(2)的变化,它的阻抗变化,并且该变化被取出作为在高频信号的幅度的变化。 一对电极端子的(5A,5B)连接到检测导体膜的两端(3A,3B)分别,电源端子和接地端子(4a和4b,分别地)形成在基材上。 用作高频放大器的半导体裸芯片(127)被安装为能够相对论文端子,由此所述裸芯片的端子直接连接到所述电极端子,电源端子和接地端子。
