摘要:
The invention relates to a method of manufacturing metal nanoparticles by using metal seed and metal nanoparticles including such metal seed. It is to provide the Au nanoparticles prepared by a method comprising: preparing a solution by adding a monosurfactant into a non-aqueous solvent; heating the solution; preparing a platinum seed solution by adding platinum salt chosen form platinum, palladium, iridium into the heated solution; and adding gold salt in the platinum seed solution.

The present invention provides a device for culturing cells. The device includes a well and a membrane. The well has an internal space and a membrane actuating control channel. The internal space has an inlet and an outlet. The membrane is provided between the membrane actuating control channel and the internal space such that the membrane actuating control channel is isolated from the internal space. The membrane is elastically varied in shape to form a three-dimensional cell culture space in the internal space.

There are provided a solar cell and a method of manufacturing the same. The solar cell includes: a solar cell unit absorbing sunlight to generate electricity; a surface treatment layer formed on at least one of upper and lower surfaces of the solar cell unit by a condensation reaction of a compound having a functional group —Y having a lone pair and an alkoxy group —OR; and a metal electrode layer bonded to the functional group —Y having the lone pair of the surface treatment layer. The solar cell has excellent energy conversion efficiency.
