A microchip for chemical reaction capable of rapidly performing an experiment irrespective of the types of the chemical substrates used for the experiment under various experimental conditions, wherein a horizontal communication path 13 comprising a plurality of chemical reaction pool portions 11, 12 and grooves communicating these chemical reaction pool portions 11, 12 to each other is formed in the surface of a diamond substrate 10 of minute size forming a substrate, a vertical communication path 20 comprising through-holes vertically communicating the chemical reaction pool portions 11, 12 to each other is provided in the diamond substrate 10, and an opening/closing valve 21 is installed at a communicating portion, and further heating/cooling means 23, 24 such as a Peltier device are installed at those positions corresponding to the chemical reaction pool portions 11, 12, respectively, whereby a variety of experiments can be performed in a verry small space without being restricted by the types of chemical substrates and by varrying the experimental conditions.
L'invention se rapporte à un microcircuit intégré pour réaction chimique permettant la mise en oeuvre rapide d'une expérience quels que soient les types de substances chimiques mises en jeu dans l'expérience et dans diverses conditions expérimentales. Ce microcircuit comporte un chemin de communication horizontale (13) comprenant une pluralité de parties (11, 12) regroupées et destinées à la réaction chimique et de rainures assurant la communication entre lesdites parties (11, 12), ledit chemin étant formé à la surface d'un substrat en diamant (10) de petite taille; un chemin de communication verticale (20) comportant des trous traversants assurant la communication verticale entre lesdites parties (11, 12), ledit chemin étant ménagé dans le substrat en diamant (10); une soupape d'arrêt (21) installée au niveau d'une section de communication, et en outre des organes de chauffage et de refroidissement (23, 24), du type élément à effet Peltier, installés en des emplacements correspondant respectivement aux parties (11, 12) regroupées et destinées à la réaction chimique. Ce microcircuit permet la mise en oeuvre d'une variété d'expériences dans un espace limité sans restriction sur le type des substances chimiques et dans des conditions expérimentales variées.
