摘要
While the function of DNA in biology is for storage of genetic information,chemists have developed methods to obtain DNA sequences with catalytic and molecular recognition functions.Thus,DNA is a highly attractive molecule for developing biosensors.DNA probes are known for their detection of complementary DNA and RNA.In addition,DNA aptamers allow for the detection of,essentially,any type of molecule.By coupling DNA with biological elements such as CRISPR-Cas12,highly sensitive detection with signal amplification can also be achieved.Overall,using DNA as a sensor component and as a target are hot areas of research for biomedical diagnosis,environmental monitoring,and food safety.
