Abstract:
A sensor chip using the technique of surface Plasmon resonance (SPR) is provided to introduce a nano gold colloid without a probe, improve productivity and economic efficiency and increase the sensitivity of chip detection. A sensor chip using a surface plasmon resonance (SPR) comprises: a intermediate layer which is formed by introducing organic single molecule having a functional group of amine(-NH2) or thiol(-SH) functional group at the one side end and thiol(-SH) functional group at the other side end on substrate in which gold is applied or dotted; a gold colloid layer which is absorbed on the intermediated layer; a fusion protein in which a gold binding protein (GBP) and protein A or G is bonded to the gold colloid layer; and an antibody which is bonded to the fixed fusion protein.
Abstract:
A substrate manufacturing method for sensor applications using optical characteristics and the substrate therefrom are provided to be used as the element of the optical instrument by giving the analysis sensitivity characteristic to the solid surface. The substrate manufacturing method for sensor applications using optical characteristics comprises the stand-by step(S20) of the nano particle dispersion solution, and the formation step(S22) of the nano particle single layer and a formation step(S24) of the metallic foil. The stand-by step of the nano particle dispersion solution is performed for reforming the surfaces of the nano particles to the hydrophobe by using functional group. The formation step of the nano particle single layer is performed in order to prepare for the nano-particles having single film based on the Langmuir-Blodgett's method. The formation step of the nano particle single layer is more performed in order to form the nano particle single film in the top of the substrate. The formation step of the metallic foil is performed to form the metallic foil on the nano particle single layer by using the vacuum deposition method.
Abstract:
A method for making glutinous rice starch for oil-and-honey pastry is provided to avoid a need for a water dipping step requiring a long period of time, and to allow production of oil-and-honey pastry in a simple and clean manner. The method for making glutinous rice starch for oil-and-honey pastry comprises the steps of: mixing glutinous rice starch with water; and applying a desired pressure to the mixture so as to apply a physical impact to glutinous rice starch particles, thereby reducing the particle size. In the mixture of starch with water, the starch is present in an amount of 5-45 wt% based on the total weight of the mixture. The pressure application step is carried out under 10,000-60,000 psi.
