Molecule selective sensor for industrial use and procedure for its preparation
First Claim
1. A process for producing an enzymatically active membrane which consists in mixing together 1-20 weight percent of acrylamide, 1-20 weight percent of polyvinylalcohol, 0.01-10 weight percent of bovine albumin, 0.0001-5 weight percent of an enzyme, 0.1-5 weight percent of glutaric aldehyde, a polymerization initiating amount of potassium persulfate and the remainder to 100 weight percent of distilled water, spreading the mixture on a protein membrane found in nature to form a thin sheet and allowing the mixture to react for 12 hours at room temperature.

Abstract
A molecule selective sensor having two permeable membranes in contacting relationship with each other, one membrane being a protein membrane found in nature, as for example, hog intestine membrane, air bladder of fish, epidermal section of mammals and reptiles, etc. and the other membrane being the reaction product of acrylamide, polyvinylalcohol, an enzyme, bovine albumin and glutaric aldehyde.
