What challenges need to be overcome to make DNA chips more applicable as storage media
Aug 24, 2023 (Nanowerk News) The hereditary molecule DNA can store a great deal of information over long periods of time in a very small space. For a good ten years, scientists have therefore been pursuing the goal of developing DNA chips for computer technology, for example for the long-term archiving of data. Such chips…

Improving food safety with Lab-in-a-Package technology
Aug 24, 2023 (Nanowerk Spotlight) In today’s interconnected world, food supply chains have grown increasingly complex, spanning multiple countries and involving numerous intermediaries. This complexity has led to a heightened risk of foodborne illnesses due to contamination. Traditional methods for detecting pathogens in food are often labor-intensive and time-consuming, requiring samples to be sent to…
