A Structure-switching Nanosensor made from DNA

Caption: A structure-switching nanosensor made from DNA (blue and purple) detects a specific transcription factor (green). Using these nanosensors, a team of researchers from UCSB has demonstrated the detection of transcription factors directly in cellular extracts. The researchers believe that their strategies will allow biologists to monitor the activity of thousands of transcription factors, leading to a better understanding of the mechanisms underlying cell division and development.
