Global nanotechnology company pSivida Limited, is pleased to announce that its UK operating subsidiary pSiMedica Limited has been granted a new Australian patent for BioSiliconTM.
Australian Patent Number 769952 provides protection for an orally administrable pharmaceutical product comprising an information carrier having a form and composition such that information is recorded by the carrier, wherein the information carrier comprises a material that is resistant to the gastric environment thereby protecting this information.
One potential application of the carrier is in the treatment of overdose patients who have consumed large quantities of a pharmaceutical product. It is essential for doctors treating such a patient to be able to identify the drug as soon as possible so that remedial action can be taken. Information about the drug, the dosage of the drug, batch number, and its expiry date may be of value. Once retrieved from the patient the information present on the carrier may be read using a microscope. The information carrier would comprise a semiconductor chip or a silicon chip. The information would be recorded by engraving the chip via photolithography or electron beam lithography. Using a semi conductor we are able to engrave large quantities of information on very small samples of less than 10 microns.
