The focus here will be on biological devices that cure diseases, prevent health issues and reverse ageing.
Wikipedia; Synthetic biology is an interdisciplinary branch of biology, combining disciplines such as biotechnology, evolutionary biology, molecular biology, systems biology, biophysics, electrical engineering, and is in many ways related to genetic engineering.
