Abstract

SE PRESENTA UN TEMPORIZADOR QUIMICO PARA UNA TIRA DE PRUEBA DE REAGENTES DE LECTURA DIRECTA QUE CAMBIA EL COLOR DESPUES DE QUE HAYA PASADO UN TIEMPO PREDETERMINADO DESPUES DE QUE EL FLUIDO BIOLOGICO HAYA SIDO APLICADO A LA TIRA. LA TIRA MIDE LA CONCENTRACION DE UN SUJETO DE ANALISIS EN EL FLUIDO. EL TEMPORIZADOR ES UN REVESTIMIENTO SECO DE UN INDICADOR, UN REAGENTE QUE CUANDO SE HIDRATA PUEDE REACCIONAR CON LA GLUCOSA PARA CAMBIAR EL COLOR DEL INDICADOR, UN INHIBIDOR PARA INHIBIR EL CAMBIO EN EL COLOR DEL INDICADOR, Y GLUCOSA. PREFERIBLEMENTE, EL REAGENTE Y LA GLUCOSA ESTAN PRESENTES EN EXCESO EN EL REVESTIMIENTO, Y EL TIEMPO QUE TARDA EN CAMBIAR DE COLOR PUEDE CONTROLARSE MEDIANTE LA CONCENTRACION DEL INHIBIDOR.
