Abstract: A device is provided for a chemical reaction between molecules immobilized on a solid phase and molecules in a solution. A chemical analysis device is also provided to capture molecules in the solution and subsequently measure the captured molecules. Reaction efficiency and sample throughput are thereby improved. The chemical reaction and chemical analysis devices use a microfluidic device channel as a reaction vessel. The channel is provided with a particular molecule immobilized on an interior surface of the channel with an obstacle positioned against the flow. In a typical reaction vessel having an enzyme immobilized in the capillary's interior surface and glass beads as obstacles, a reaction solution can move either in one direction or back and forth to react with the immobilized enzyme. The flow of the reaction solution is not laminar such that a reaction between the particular molecule and the reaction solution proceeds at high efficiency.

Abstract: A microchamber including a glass substrate which is transparent to a specific wavelength, an absorbent region which absorbs the specific wavelength, and a melting substance region which does not absorb the specific wavelength, is solid at room temperature and melts when heated, which regions are layered on the glass substrate. The absorbent region, is irradiated with a focused light beam of the specific wavelength and locally heated in the vicinity of the converging rays, so that the melting substance region is locally melted at a portion adjacent to the absorbent region, thereby forming a cavity as the focused light beam moves. Accordingly, the shape of the microchamber can be arbitrarily changed in accordance with the process of cell culture.

Abstract: There is provided means for analyzing organism-related molecules, dealing with multi item analysis, that are captured according to probe species, and for collecting according to the probe species. A magnetic micro-particle array is fixed with magnets that are configured with magnetic micro-particles in a capillary and with an array of glass beads to which DNA probes of different types from each other are immobilized. A syringe pump and a cross valve are operated to circulate a sample solution in the magnetic micro-particle array, which is reacted with probe DNAs on a glass bead with a probe. Subsequently, a washing solution is introduced to wash inside of the capillary. Next, respective beads are measured for fluorescence intensities. Furthermore a particular bead is collected based on results of fluorescence measurement. Target molecules captured on a surface of the collected bead may be separated by heat-denaturation, which then may be subjected to next analysis.
