TL;DR: In this paper, it was shown that when pressure is applied to the surface of a quartz crystal, an electrical circuit can be formed, which is called piezoelectricity.
Abstract: I. INTRODUCTION Piezoelectricity was first discovered in 1880 by the brothers Pierre and Jacques Curie.1 They observed that when pressure is applied to the surface of a quartz crystal an electrical...

TL;DR: In this article, a new fiber-optic probe for the determination of glucose is developed, where glucose oxidase is immobilized on a preactivated Immunodyne membrane by direct application of the enzymatic solution to one side of the membrane.
Abstract: A new fiber-optic probe for the determination of glucose is developed. Glucose oxidase is immobilized on a preactivated Immunodyne membrane by direct application of the enzymatic solution to one side of the membrane. The membrane is then placed around the common end of a bifurcated glass fiber optic bundle, and immersed in the sample cell which contains the glucose sample, peroxidase and a colorless dye. Glucose is quantified by the color change when the reaction takes place.
