Single nucleotide polymorphism and short tandem repeat detection using carbon nanotubes
DNA sequences among individuals are unique in part due to mutations and variations such as single nucleotide polymorphisms (SNPs) and short tandem repeats (STRs). These minor changes lead to severe genetic disorders, trait expression, and differences in drug reactions. Techniques that determine an individual's SNP and STR pattern can provide crucial information to healthcare providers, allowing for personalized medical regimens to optimize care. However, current techniques are time consuming and expensive. This technology describes a method to detect such SNPs and STRs by measuring the electrical signals of an individual's DNA via carbon nanotubes. Changes in conductivity allow researchers to determine variations in DNA. Potentially, the technology can be used as a diagnostic tool to determine genetic differences that can lead to more accurate diagnoses and individualized treatment plans.
