Nanostructures Used As Biosensors Allow Diseases Or Allergens To Be Detected
( Elhuyar Fundazioa ) The industrial engineer Iñaki Cornago-Santos has developed structures on a nanometric scale that can be used as biosensors for medical, food or environmental sectors to detect diseases, allergens or contaminants; or can be used to reduce the reflection of solar cells in order to increase their efficiency. This is what he says in his Ph.D. thesis defended at the NUP/UPNA ... Read News
