Schematic representation of antibody-antigen selective recognition

Bio-Recognition

 Various optical manifestations used for biosensing

 

Hybridization with the target DNA molecules of complementary sequence or unwinding with the increase of temperature, change of pH or denaturing agent produces an increase of fluorescence.

Molecular beacon approach for biosensing

 

DNA probing by hybridization of the DNA unit/single-stranded (oligonucleotides) in the loop with a complementary sequence in the DNA analyte
