A Method for the Fabrication of Micro-Diamond Hollow Shells
The technique provides a method for the production of inert microscopic diamond shells which can be used for the preservation, storage and transport and delivery of molecules in a controlled fashion.
An inert material such as diamond provides advantages in that there is no cross reactivity of the carrier shell with either the contents of the shell or the medium into which is being introduced ensuring long term stability.
The procedure can be applied to a number of shapes including cubes, spheres, cylinders. Each shape has an aperture which allows material to be placed inside for storage, preservation or transport purposes. The size of the aperture can be controlled thereby controlling the rate of release of material from the hollow shell.
Key Benefits
- The size of the aperture and therefore the speed of compound release can be controlled
- Further control of retention and release of compounds can be included by surface attachment of the compound to the diamond
- Size of shell can range from (several microns to thousands of microns)
Applications
- Preservation and storage of biological and chemical samples e.g. DNA, bacteria,
- Controlled delivery of biological or chemical compounds e.g. drug delivery (slow release), cosmetics (controlled release of perfumes or colorants) , textiles (improved dye retention)
- Faster targeting of treatment area – reduced operator skill required.
- Molecular biological applications – e.g. DNA separation and detection
