341 Photoelectric endpoint detection US3723062D 1970-12-21 US3723062A 1973-03-27 DAHMS H
A method and apparatus useful for colorimetric titration utilizes an indicator which changes from one colored form to another at or near an endpoint, and an optical endpoint detection system which generates signals responsive to the relative concentrations of the different colored forms of the indicator. The endpoint is indicated when the ratio of the logarithms of the signals reaches a predetermined value.

Disclosed are fluorescent protein sensors for measuring the pH of a sample, nucleic acids encoding them, and methods of use. The preferred fluorescent protein sensors are variants of the green fluorescent protein (GFP) from Aequorea victoria. Also disclosed are compositions and methods for measuring the pH of a specific region of a cell, such as the mitochondrial matrix or the Golgi lumen.

Disclosed are monolithic bioelectronic devices comprising a bioreporter and an OASIC. These bioluminescent bioreporter integrated circuit are useful in detecting substances such as pollutants, explosives, and heavy-metals residing in inhospitable areas such as groundwater, industrial process vessels, and battlefields. Also disclosed are methods and apparatus for environmental pollutant detection, oil exploration, drug discovery, industrial process control, and hazardous chemical monitoring.
353 Method and apparatus for detecting amine producing organisms in the vagina US118502 1998-07-17 US6117090A 2000-09-12 James C. Caillouette
A method of detecting pathogenic bacteria in the vagina, includes providing a vaginal moisture receiver receivable into the vagina; providing a reactant which changes color when contacted by moisture containing pathogenic bacteria; receiving vaginal moisture on the receiver; and contacting reactant with vaginal moisture on the receiver, whereby a change in color at the receiver indicates the presence of pathogenic bacteria.
354 Reagent for determining the ionic strength and/or the specific weight of aqueous liquids and method US950981 1997-10-15 US6114170A 2000-09-05 Klaus Habenstein
The invention relates to a method for determining the ionic strength and/or the specific weight of aqueous liquids and a reagent for this purpose, the composition of the reagent being such that the color change indicating the ionic strength is essentially directly dependent on the specific weight of the liquid to be determined and not on a pH shift.
355 Method of making a pH and amine test element US040151 1998-03-17 US6113856A 2000-09-05 Paul J. Lawrence; Peter U. Ly; David R. Shockey
Tests for elevated pH and volatile amines in aqueous fluids are disclosed, including tests useful in the diagnosis of bacterial vaginosis and in other biological conditions. By using formulated indicators and indicators held in matrices that are permeable to gas but not to liquid, the tests provide clear and sharp transitions detectable by visual or machine-readable means rather than by subjective judgments such as small gradations in color or olfactory determinations. The tests lend themselves readily to iconic readouts of the test indications and to the inclusion of positive and negative controls.
356 Estrogen or estradiol need determination by vaginal acidity determination US848906 1997-05-01 US6083178A 2000-07-04 James C. Caillouette
In the method of determining need for human estrogen or estradiol level change, the steps include determining local acidity proximate a moist wall surface of the vagina, as differing from desired threshold level, and administering sufficient estrogen or estradiol to result in change in acidity toward such level.
