Nano-Antennas light up to Sequence DNA

 

Dr. Aksimentiev from the University of Illinois and researchers at TU Delft in The Netherlands have developed a plasmonic nanopore technology for DNA sequencing. One of the hurdles facing current nanopore-based DNA sequencing technologies is the inability to control DNA speeds passing through the pore. The group has developed nano-antennas that can focus high intensity light on the nanopore to create a "hot-spot" to trap and slow down DNA movement, which can help read long lengths of DNA more efficiently.
