Provided are a novel carboxymethyl cellulose (CMC) structure and a method for producing the same. The CMC structure of the present invention is useful as a medical material and particularly as an adhesion-preventing material, and has good biocompatibility and bioabsorbability and controllable periods of functioning and dissolving, or has both effects for preventing adhesions and wound healing.The CMC structure of the present invention is substantially composed of carboxymethyl celluloses, comprising an acid carboxymethyl cellulose and an alkaline metal carboxymethyl cellulose in a mixed state. The method of production of the present invention comprises subjecting the alkaline metal (or acid) carboxymethyl cellulose structure to an acid (or alkali) treatment, wherein the acid (or alkali) treatment is terminated before the alkaline metal (or acid) carboxymethyl cellulose is fully converted to the acid (or alkaline metal) carboxymethyl cellulose.

An aqueous solution containing sulfuric acid and hydrogen peroxide is used for a soft etchant in a soft etching step in a smear removing process performed prior to a catalyst applying process for chemical copper plating after formation of via holes through an insulating layer of a multi-layer substrate by irradiation of laser. The concentration of sulfuric acid is 2.4 times or less than the concentration of hydrogen peroxide. Preferably, the concentration of sulfuric acid is in a range of 9 to 90 g/l, and the concentration of sulfuric acid is lower than the concentration of hydrogen peroxide. More preferably, the concentration of sulfuric acid is in a range of 9 to 18 g/l, and the concentration of hydrogen peroxide is in a range of 33 to 38.5 g/l. As a result, smear can be certainly removed without excessively etching a conductive layer in the smear removing process.

A coloring layer composition for a chromatic device of the present invention contains an oxide such as tungsten oxide or niobium oxide and so on as a solute, water and an organic solvent such as propanol. In the step of forming a reduction coloring layer, a film is formed by using a peroxotungstic acid solution containing 100 parts by weight of WO.sub.3.aNb.sub.2 O.sub.5.bH.sub.2 O.sub.2.cH.sub.2 O (wherein a, b and c are each a positive number) as a solute, 20 to 120 parts by weight of water and 80 to 800 parts by weight of n-propanol as an organic solvent. At this time, a dip coating method is used, and the vertical pulling-up speed is less than 15 cm/min. The present invention can effectively prevent unevenness and separation of the reduction coloring layer.

Disclosed is a colorimetric sensor comprising polydiacetylene membrane liposomes, a polydiacetylene membrane film or fine particles coated with a polydiacetylene membrane, in which the polydiacetylene membrane is incorporated with a protein having a reduced molecular weight low enough not to cause color change in the polydiacetylene membrane. The examples of the reduced-molecular-weight proteins include an antibody Fab′ fragment, an antigenic protein of molecular weight of 100,000 or less, and a peptide consisting of 3-20 amino acid residue, which undergo an antigen-antibody reaction with an antigen or antibody contained in a sample. As the reduced-molecular-weight protein is also employed a combination of single-stranded DNA of 100 bases or less which hybridizes with single-stranded DNA contained in a sample to form a double-stranded DNA, and an antibody which reacts with said double-stranded DNA but does not react with the single-stranded DNA contained in the sample. A method for analysis of biosample is also disclosed, which comprises contacting the colorimetric sensor with a solution sample and utilizing an absorption measurement or a visual observation with the naked eye to detect color change in the polydiacetylene membrane.
