A highly sensitive nucleotide sensor has been developed by New Mexico Tech researchers which utilizes special light-emitting properties of nanoparticles in identification of individual components of single strands of DNA and RNA. It is quite sensitive and specific and can differentiate a single base mismatch in a 26 base nucleotide target. This is being regarded as an important finding with regards to the study and treatment of a number of genetic based diseases. One of the disease is Sickle Cell Anemia which is caused due to single base mismatch on just one base protein. This new finding might also be used in detection and killing of cancer too.
