摘要:
Disclosed are biochips having a high detecting sensitivity with readiness in fabrication of microarray, and a method for fabricating the same, in which a solid support wound with fibers is immersed in a solution containing biomolecules to immobilize the biomolecules onto the fiber, and the individual fibers with the biomolecules immobilized thereon are straightened and arranged. The arranged fibers are embedded with a defined material and cut in a direction perpendicular to the lengthwise arrangement direction of the fibers to obtain thin chips. The chips are placed on a substrate to remove the material used for embedding and thereby remain fibers with the immobilized biomolecules on the substrate. This biochip fabrication method immobilizes a great number of biomolecules onto the fibers having a large surface area to enhance the detection sensitivity and allows production of a great number of substrates with an array of biomolecules immobilized simultaneously.

A biochip including a DNA chip and a protein chip and a method for patterning and measuring biomaterial of the same are disclosed. The method for patterning a biomaterial of the biochip including a reflecting layer and an active layer on a substrate includes the steps of: rotating the biochip; successively irradiating pulse type laser beams to the rotating biochip to activate predetermined regions of the active layer; and fixing a biomaterial pattern on the activated predetermined regions. A method for measuring the patterned biomaterial includes the steps of: reacting a biomaterial labeled with at least one dye material with the biochip; rotating the biochip reacted with at least one biomaterial; successively irradiating laser beams to the rotating biochip; and detecting and processing light derived from the biochip as a result of reaction of the biomaterial to measure the biomaterial. Thus, the biochip having reliability and high packing density can be fabricated at low cost and the biomaterial of the biochip can be measured at high speed without using expensive equipments.

The present invention relates to Corynebacterium sp. that is transformed with an Escherichia sp.-derived fructokinase gene to express fructokinase showing a sufficient activity of converting fructose into fructose-6-phosphate, thereby preventing unnecessary energy consumption, and a method for producing L-amino acids using the strain. The transformed Corynebacterium sp. of the present invention is able to express fructokinase from the Escherichia-derived fructokinase gene to prevent unnecessary energy consumption during fructose metabolism, leading to more cost-effective production of L-amino acids. Therefore, it can be widely used for the effective production of L-amino acids.

An image sensor capable of boosting a voltage of a floating diffusion node is provided. The image sensor includes a floating diffusion node and a storage element which are in a semiconductor substrate. The image sensor includes a first light-shielding material formed over the floating diffusion node, and a second light-shielding material formed over the storage diode. The second light-shielding material is separated from the first light-shielding material. The image sensor also includes a first voltage supply line configured to apply a first voltage to the first light-shielding material and a second voltage supply line configured to apply a second voltage lower than the first voltage to the second light-shielding material.

An image forming apparatus includes a main body, a document board to open and close an upper side of the main body while being pivoted, and a shock absorber to reduce impact generated when the document board closes the upper side of the main body, wherein the shock absorber includes a link pivotably mounted, at a first end thereof, to the document board while guide protrusions are formed at a second end thereof, and a guide slot formed so that each guide protrusion is movable. Since the guide slot applies a pressure gradually increased from the first end side of the guide slot to the second end side thereof, to the guide protrusion, a speed of the guide protrusion and a pivoting speed of the document board are restricted below a certain speed when the upper side of the main body is closed through the document board.
