    Abstract: A method for growing a thin InGaAs or InAlAs layer with heavy lattice mismatching on a GaAs substrate by a MOCVD process is described. A first material gas is injected by a MOCVD process to grow a buffer layer on a GaAs substrate to a prescribed thickness. After stopping the injection of the first material gas for a few seconds, a second material gas containing a column III element is injected at a prescribed temperature. A third material gas containing a column V element is injected to grow, on the buffer layer, a thin metallic layer of a binary compound containing the column III element of a high concentration to a thickness of 2 nm or less. After a prescribed time from the injection of the third material gas, In and Ga gases or In and Al gases, mixed in the prescribed proportion are injected in an atmosphere of said third material gas to grow a thin InGaAs or InAlAs layer on the thin metallic layer.

    Abstract: The invention provides methods, compositions, systems, and kits that include an enzyme/substrate co-delivery system. The liquid delivery system includes at least one enzyme encapsulated in a water-soluble polymeric matrix and a substrate for the enzyme in a carrier liquid in which the polymeric matrix is insoluble. When water is added, the polymeric matrix is solubilized and enzyme is released from the matrix, permitting catalytic action upon the substrate.
