Abstract

SENSOR DE TESTE ELETROQUìMICO COM VOLUME DE AMOSTRA REDUZIDO. Um sensor de teste eletroquímico para detectar a concentração de um produto analisado em uma amostra de teste de fluido compreende uma base, uma camada dielétrica, uma camada de reagente e uma tampa. A base fornece uma trajetória de fluxo para a amostra de teste de fluido tendo em sua superfície um contra-eletrodo e um eletrodo de trabalho adaptado para se comunicar eletricamente com um detector de corrente elétrica. A camada dielétrica forma uma janela dielétrica através da mesma. A camada de reagente inclui uma enzima que é adaptada para reagir com um produto analisado. A tampa é adaptada para corresponder com a base e auxiliar na formação de um espaço capilar com uma abertura para a introdução da amostra de teste de fluido na mesma. Pelo menos uma parte da largura do contra-eletrodo é maior que a largura do eletrodo de trabalho.
