An electro-microchip was successfully used to detect the impedance signals of various Methamphetamine (MET) concentrations based on the developed competitive-immunoassay method. MET is a commonly used drug often abused by drug addicts and can cause irregular behavior; therefore, MET concentration detection is important for quantitative analysis. In this study, the gold nanoparticles (AuNPs) were …

A novel bidirectional dc-dc converter is presented in this paper. The circuit configuration of the proposed converter is very simple. The proposed converter employs a coupled inductor with same winding turns in the primary and secondary sides. In step-up mode, the primary and secondary windings of the coupled inductor are operated in parallel charge and series discharge to achieve high step-up …
