Abstract:
The present invention provides a porous sustained-release body in which transparency of a porous carrier changes. The porous sustained-release body includes an inorganic monolithic porous body  1  including a skeleton body  2  of an inorganic compound and air gaps  3,4  having a three-dimensional continuous network structure formed in the skeleton body  2,  and a sustained-release liquid absorbed into air gaps  2, 3,  wherein the inorganic monolithic porous body  1  is opaque at an initial state, which is a state before absorption of the sustained-release liquid in which air exists in the air gaps, and refractive index of the sustained-release liquid and refractive index of the skeleton body are the same within an error range within which a portion in which the sustained-release liquid is absorbed into the air gaps changes to transparent or semitransparent.

Claim (Index 10):
A sustained-release method comprising:\n using an inorganic monolithic porous body including a skeleton body of an inorganic compound and air gaps having a three-dimensional continuous network structure in which the inorganic monolithic porous body is opaque at an initial state in which air exists in said air gaps; infiltrating a sustained-release liquid, in which a refractive index of the sustained-release liquid and a refractive index of said skeleton body are the same within an error range within which a portion into which said sustained-release liquid is absorbed into said air gaps changes to transparent or semitransparent, into said air gaps to change said inorganic monolithic porous body from an opaque state, which is said initial state, to a transparent or semitransparent state at a portion in which said sustained-release liquid is absorbed into said air gaps; and then carrying out gradual emanation of said sustained-release liquid from said inorganic monolithic porous body to recover an opaque state at a portion at which said sustained-release liquid is emanated from said air gaps.
