![Development of a detection system for disease-related genes](images/theme07.jpg)
To evaluate the risk of disease development, such as cancers and lifestyle-related diseases, individual differences of a single nucleotide in genes (single nucleotide polymorphism, SNP) are generally analyzed. However, sensors based on conventional systems may misrecognize genes other than the disease-related genes depending on the target sequences used. We are developing new DNA sensors based on the interaction between solution and DNAs to increase the recognition ability of a target gene by reduction of such misrecognition.
