Abstract: A display device includes a display panel including a main area, a bending area at which the display panel is bendable, and a sub area, in order. The main area includes a display area and a non-display area which is adjacent to the display area. The bending area connects the sub area to the main area at the non-display area thereof, and is recessed from outer side surfaces of the main area and the sub area, to define a recess portion of the display panel at the bending area.

Abstract: Disclosed is a microfluidic paper chip for detecting a microorganism, a method for preparing the same and a method for detecting the microorganism using the same. The microfluidic paper chip includes a lysis layer and a chromogenic layer which are laminated in this order. The lysis layer is composed of a hydrophilic paper containing a lysis reagent composition and the chromogenic layer is composed of a hydrophilic paper containing a chromogenic reagent.

Abstract: A preparation method of silver nanostructure for use as substrate of surface-enhanced Raman scattering (SERS), which can ensure the ‘hot spot’, which provides the considerably very intense electromagnetic field in which the silver nano-structures have uniform average size and very strong forms of particles, by characterizing a variety of conditions such as, for example, concentration of AgNO3 and reductant, reaction temperature, stirring velocity, single dropwise addition quantity, dropwise addition rate, or total dropwise addition quantity, which were unpredictable in the conventional silver nanoparticle preparation method using AgNO3 aqueous solution and NaBH4 reductant, so that the preparation method can be advantageously applied for the mass production of silver nano-structures for use as substrate of SERS because the method can provide multimer form with enhanced SERS signals and reproducibility, and also ability to selectively control the particle size.
