An apparatus for sensing biomolecules includes: a storage in which a solution containing a target material is received; a sensor configured to sense the target material; and a flow controller connected between the storage and the sensor to supply the solution to the sensor, wherein the flow controller controls a solution flow to supply the solution containing the target material and the solution containing no target material in an alternating manner. According to the apparatus for sensing biomolecules, the sensing device always achieves a sensing offset, and consequently, long-term continuous measurement is enabled, leading to the maximized usage efficiency of the sensor, and the value of quantitative measurement can be obtained with high precision.

A metamaterial for an electromagnetic wave filter includes a substrate; and a film disposed on the substrate and having a set of slots arranged to form a rotationally symmetric pattern, which is patterned in an intaglio shape, or a set of structures arranged to form a rotationally symmetric pattern, which is patterned in an embossed shape, to control a transmission rate according to polarization of an electromagnetic wave incident on the film. The set of slots or the set of structures have an array angle that is determined such that the transmission rate and a reflectivity thereof have constant values according to the polarization of the electromagnetic wave incident on the film, and have a chloroplast molecular structure pattern in which the set of slots or the set of structures are arranged in pentagonal and hexagonal shapes.

Disclosed is an apparatus for graphene wet transfer, which includes: a reservoir body having at least two reservoirs; a barrier structure located on the reservoir and having at least one separated space formed by barriers; and a substrate frame located below the barrier structure and having at least one substrate accommodation groove for accommodating a target substrate to which graphene is transferred. Here, each reservoir may be filled with a solution for a wet transfer process, and the graphene may be separately located in each separated space in a floating state in the solution.
