Electrochemical biosensor systems or apparatus, components thereof, and methods for quantitatively measuring or assaying concentrations of selective substrates or metabolites in aqueous media as a function of electrochemical response to hydrogen peroxide concentration, using immobilized enzyme electrode means selective for the substrate or metabolite being measured.

Methods and materials are provided for coating hydrogel capsules which contain encapsulated meristematic tissue substantially free of intact seed coat with a membrane which controls the migration of solvents and their included solutes between the capsule and its environment, thereby creating an analog to natural botanic seed having an artificial seed coat which provides the benefits of natural seed coat. The membranes may be formed of a single compound or various compounds which provide control over the migration of distinct elements.

A method of enhancing photographic images of low optical density is disclosed which includes use of a luminescent system, the components of which system include, at least, photoluminescent material and a source of photons for exciting the same to luminescence. A photoluminescent replica of the low optical density photographic image is produced which replica is exposed to photons required for luminescence of the photoluminescent image replica which luminescence is recorded, or photographed, for an amount of time necessary to achieve enhancement of the photographic film image. The image enhancement method may be used for the enhancement of photographic images produced by photographic processes including, for example, those which involve the use of different radiant energy sensitive material such as silver halide as used in `conventional` photography, photoconductive material as used in electrophotography, organic compounds as used in diazo photographic processes, and the like.
