Title: Electrochemical detection and measurement of enzyme substrates - by oxidn. or redn. of coenzyme, then regenerating this and measuring the current produced
Inventor: BLAEDEL WALTER J
IPC: C12N11/02
Filed: 1976-12-27
Abstract: Electrochemical detection or determination of an enzyme substrate (A), capable of permeating through a membrane, comprises mixing (A) in aq. soln. with a coenzyme (B) in presence of an enzyme (C). In the presence of (C), (A) either oxidises or reduces (B) by an electron transfer process. An electrical potential is applied to the surface of an electrode in the sample which is sufficient to oxidise (reduce) reduced (oxidised) (B) formed in the process. The electrical current generated, which is a function of the concn. of (A), is reduced. Pref. (A) is used to reduce NAD or NADP, or to oxidise NADH or NADPH, (B) and (C) are pref. immobilised in electrochemical contact with the electrode surface. Used for detecting/analysing e.g. lactate or glucose. Since (B) is regenerated no reagents other than those immobilised on the electrode are needed.

Title: Sea water desalination - based on evaporation and condensation coupled by heat pump
Inventor: KUECKENS ALEXANDER
IPC: C02F1/04
Filed: 1978-01-07
Abstract: In a sea water desalination system the condenser of a heat pump is used to heat the sea water and to initiate its evaporation.
