Pagination or Media Count:
Isolated frog skin used as a transducer whose bioelectrical potential is measured as a function of chemical species and concentration, is shown to offer large, reproducible, reversible changes to a variety of organic substances of low molecular weight, over a concentration range of at least five log units. A high degree of variability of response between frog skins, and a lack of data on ultimate sensitivities at usefully low levels for selected substances, are major problems that remain to be examined.
