Silicate matrix, its preparation and application

  • Summary:

    The object of the inventions is silicate matrix, its preparation and application. This matrix is made by mixing of two sol-gel precursors including the basic one and second, which modify the matrix with positive or negative charge. this matrix found application for immobilization of carbon nanoparticles, carbon nanotubes or biological molecules, e.g. enzymes, what allows to use it as an element of sensor do thiocholine, dopamine or organophosophate pesticide. This applications are the part of the invention as well.
