Abstract

SE DESCRIBE UN APARATO ANALITICO QUE INCLUYE UN TRANSDUCER PIROELECTRICO O TERMOELECTRICO (10) DE FORMA ALARGADA. ESTA PROVISTO DE MICROLECTRODOS (12, 14) Y DE UNA O MAS GOTAS DE REACTIVO (16) QUE SE DEPOSITAN EN LA SUPERFICIE DEL TRANSDUCER. UNA PEQUEÑA CANTIDAD DE MUESTRA BIOLOGICA O DE OTRO TIPO SE DEPOSITA SOBRE LAS GOTAS DEL REACTIVO QUE IMPLICAN UNOS CAMBIOS COLORIMETRICOS SELECTIVOS. SE ILUMINA EL TRANSDUCER DESDE SU PARTE INFERIOR POR MEDIO DE FUENTES DE LUZ LED (24) Y LA ABSORCION DE LA LUZ EN LAS ZONAS DEL REACTIVO SE DETECTA EN FORMA DE UN CALENTAMIENTO MICROSCOPICO EN LA SUPERFICIE DEL TRANSDUCER. LA DE SEÑAL ELECTRICA PRODUCIDA POR EL TRANSDUCER PIROELECTRICO SE PROCESA PARA SUMINISTRAR INFORMACION ANALITICA.
