Abstract: Provided is a method for screening a biological molecule rapidly and economically with high-throughput using microbeads encoded with silver nanoparticles and a chemical compound and dielectrophoresis. A biological screening method particularly utilizes microbeads encoded with silver nanoparticles and a specific chemical compound and dielectrophoresis. Since this screening method does not use a fluorescent material and a dying agent, which are typically used in the conventional screening method, it is non-toxic and economical. Also, this screening method allows simultaneous identification of many target materials. Accordingly, a leading compound can be screened within a short period of time, and thus, this screening method can be implemented as an economical and effective system for developing new pharmaceutical products.

Abstract: A microwave tunable filter having some advantages as follows: a) the integration of MEMS tunable filter and MMIC; b) the very low signal transmission loss and low dispersion; and c) the drastic variation and linear characteristic of frequency by means of MEMS capacitor and an external control signal. The microwave tunable MEMS filter includes a plurality of unit resonant cells, each unit resonant cell being formed by various serial and parallel combination of an inductor, a capacitor, a transmission line, and a variable MEMS capacitor, whereby capacitance variation of the variable MEMS capacitor in the unit resonant cell converts a resonant frequency of the unit resonant cell to thereby convert a center frequency of the filter.
