The collection and preservation of biological material for further DNA and RNA analysis are critical to many biomedical fields, from medical diagnostics to forensics and biodiversity conservation. The Forensic DNA lab at the University of the Western Cape has developed a novel, proprietary DNA

The invention relates to a method of fabricating a commercially viable biodegradable and transparent resistive random-access memory (ReRAM) chip with substantially high (>7 orders of magnitude) resistive switching behaviour using low operating power. The method makes use of a simple and affordable
