Latest Patents

One of Uchimura's latest patents is an optical analysis chip. This analysis tool is designed for use in optical analysis and comprises a detection unit with through-holes penetrating through the surface and the rear side of a base material. The detection unit includes a plurality of voids that allow a liquid to pass through by capillary action, communicating with the through-holes. The through-holes are formed with a size that enables a liquid to be held by surface tension. By irradiating the detection unit with light, it is possible to obtain transmitted light that has been transmitted through a liquid film. Analyzing this transmitted light allows for the appropriate quantification of a target component in a sample.

Another significant patent involves sulfonated pulp fibers and methods for producing them. The objective of this invention is to provide a sulfonated fine cellulose fiber with excellent transparency and a sulfonated pulp fiber suitable for this application. The sulfonated pulp fiber comprises a plurality of cellulose fibers, with a portion of hydroxyl groups substituted with sulfo groups. The introduction amount of sulfur is adjusted to be higher than 0.42 mmol/g while maintaining the fiber shape, and the water retention value is adjusted to 150% or more. This innovation improves the flexibility in handling the pulp fiber while maintaining its shape.
