Abstract
A bioelectrochemical multiple measurement system with ion-selective fl ow-through sensors for determination of pH, ionic activities and conce ntrations of transmembraneous ionic transports is described. Non-invas ive electroanalysis during photosynthesis was realized by development of new solid-state contacts insensitive to Light and oxygen. Continuou s measurement of Ca2+, K+, Cl- and pH demonstrates the known intake of potassium ions by Vicia faba L. guard cells under the influence of li ght. Glucose intensifies the effect.
