Abstract

В изобретении предложены способы для обнаружения и идентификации аналитов, а также способы изготовления датчиков для обнаружения аналитов. Аналит (810) воспринимается датчиками (820), выходные сигналы которых изменяются при воздействии аналита. Эти электрические сигналы могут быть обработаны (830) при помощи фильтрации и усиления. В одном из вариантов в единственной интегральной схеме образовано множество датчиков. Указанные датчики могут иметь различный состав образующего материала.Международная заявка была опубликована вместе с отчетом о международном поиске.
