Biotechnology Advances, 1997
Compared to advances in enzyme sensors, immunosensors, and microbial biosensors, relatively little work exists on DNA based biosensors. Here we review the DNA based biosensors that rely on nucleic acid hybridization. Major types DNA biosensors--electrochemical, optical, acoustic, and piezoelectric--are introduced and compared.

DNA electrochemical biosensors
Fresenius' Journal of Analytical Chemistry, 2001Disposable electrochemical DNA-based biosensors are reviewed; they have been used for the determination of low-molecular weight compounds with affinity for nucleic acids and for the detection of the hybridisation reaction. The first application is related to the molecular interaction between surface-linked DNA and the target pollutants or drugs, in ...

Despite the many designs of devices operating with the DNA strand displacement, surprisingly none is explicitly devoted to the implementation of logical deductions. The present article introduces a new model of biosensor device that uses nucleic acid strands to encode simple rules such as "IF DNA_strand(1) is present THEN disease(A)" or "IF DNA_strand ...

DNA nanotechnology-enabled biosensors
Biosensors and Bioelectronics, 2016Biosensors employ biological molecules to recognize the target and utilize output elements which can translate the biorecognition event into electrical, optical or mass-sensitive signals to determine the quantities of the target. DNA-based biosensors, as a sub-field to biosensor, utilize DNA strands with short oligonucleotides as probes for target ...

Molecularly imprinted polymers-based DNA biosensors
Analytical Biochemistry, 2021In multiple biological processes, molecular recognition performs an integral role in detecting bio analytes. Molecular imprinted polymers (MIPs) are tailored sensing materials that can biomimic the biologic ligands and can detect specific target molecules selectively and sensitively.
