A new approach to detecting DNA has been developed by researchers at the University of California, Santa Barbara. The team has developed a nano-mechanoelectrical technique that will allow for DNA to be detected at much lower concentrations than current methods allow. This new technique is based on the use of nanoscale cantilevers that vibrate when exposed to electric fields. The vibration of the cantilevers can then be used to identify the presence of DNA molecules. This approach is expected to be more sensitive than current methods and could lead to new ways of detecting and treating diseases.
