In some aspects, the invention relates to a porous implant, comprising a resorbable or bio-erodible porous silicon-based carrier material; a reservoir formed within the body of the porous silicon-based carrier material; and a beneficial substance disposed within the reservoir.

Implants for administering substances and methods of producing implants

A porous silicon implant impregnated with a beneficial substance, such as a micromineral required for healthy physiology, is implanted subcutaneously and is entirely corroded away over the following months/year to release the beneficial substance in a controlled manner. In a second embodiment the implant may have a large number of holes which contain beneficial substance and which are closed by bio-erodible doors of different thickness so as to stagger the release of the beneficial substance over time as the doors are breached.

Methods of producing porous resorbable implants

A porous silicon implant impregnated with a beneficial substance, such as a micromineral required for healthy physiology, is implanted subcutaneously and is entirely corroded away over the following months/year to release the micromineral in a controlled manner. In a second embodiment the implant may have a large number of holes which contain beneficial substance and which are closed by bio-erodible doors of different thickness so as to stagger the release of the beneficial substance over time as the doors are breached.

Methods of producing mesoporous drug delivery implants

A porous silicon implant impregnated with a beneficial substance, such as a micromineral required for healthy physiology, is implanted subcutaneously and is entirely corroded away over the following months/year to release the micromineral in a controlled manner. In a second embodiment the implant may have a large number of holes which contain beneficial substance and which are closed by bio-errordable doors of different thickness so as to stagger the release of the beneficial substance over time as the doors are breached.

Metalorganic precursors for deposition of strontium tantalum and strontium niobium oxides by MOCVD techniques have the formula Sr&lsqb;M(OR ) L &rsqb; wherein x is form 1 to 6; M is Ta or Nb; R is a straight or branched chain alkyl group; and L is an alkoxide group.

Precursors for growth of heterometal-oxide films by MOCVD

Zirconium precursors for use in depositing thin films of or containing zirconium oxide using an MOCVD technique have the following general formula: Zr (OR) L, wherein R is an alkyl group; L is a &bgr;-diketonate group; x&equals;1 or 2; y&equals;2, 4 or 6; and z&equals;1 or 2.
