Patent number: 5135852Abstract: The invention relates to a piezoelectric biosensor device and also to a method and a system utilizing a piezoelectric biosensor device for detecting metabolic growth requirements, antibiotic responses, and the specific bacterial products of microorganisms. When a microorganism is grown in an appropriate nutrient medium containing a metabolic product responsive polymer, metabolic products of the organism acidify the medium and precipitate a polymer metabolic product complex which deposits or accumulates on the surface of a piezoelectric biosensor device. The mass change on the surface of the device resulting from this deposit produces a change in the resonant frequency of the piezoelectric biosensor device which can be used to determine the growth and type of microorganism.Type: GrantFiled: July 25, 1989Date of Patent: August 4, 1992Assignee: E. I. Du Pont de Nemours and CompanyInventors: Richard C. Ebersole, Robert P. Foss, Michael D. Ward
