Abstract: Disclosed is a method for manufacturing a high-density neural probe including needles having various forms. The method, in which only a photolithography process and an etching process are used, simplifies a manufacturing process of the neural probe, minimizes changes in the characteristics of the neural probe depending on process equipment or conditions, and may thus ensure a high yield, thereby being advantageous in terms of commercialization. In addition, various forms of needles may be manufactured depending on the shape of patterns included in a mask, the height of the needles may be controlled by adjusting the size of the patterns and the gap between the patterns, and thereby, a neural probe having a plurality of needles having different heights may be manufactured.

Abstract: The present invention relates to a composition for producing 2,3-butanediol by using ethanol and synthetic gas and a 2,3-butanediol production method. A composition according to an aspect of the present invention includes ethanol as an active ingredient. In the case where a 2,3-butanediol production strain is inoculated into a medium containing the composition and cultured and a synthetic gas is added thereto, 2,3-butanediol, which is a biofuel and a chemical substance, can be economically produced with ethanol serving as a substrate. In the metabolism process, the carbon flux can be concentrated on the production route of the target material, whereby the composition has an excellent effect of increasing the production efficiency of 2,3-butanediol and enhancing the productivity of 2,3-butanediol by controlling only fermentation conditions such as amounts of the synthetic gas or ethanol and stirring speeds of the medium.
