ABSTRACT

The advent of fast and easy DNA testing has given the space for the Science to develop small and easy-to-handle equipments called Biosensors. DNA based biosensors have been proven very useful and are accorded with much importance in detecting the target genes responsible for diseases. This article enlists different types of biosensors, their basic principle of operating system, the preparation of DNA microarrays, lab-on-a-chip and their role in diseases diagnosis. DNA biosensors provide swift, sensitive, selective, simple and economical detection of DNA hybridization. New strategies for DNA biosensor are enumerated and are used meticulously in recent trends and for future directions. Carbon nanotubes (CNTs) amplify the electrochemical signal when used with DNA hybridization. Electrochemical, piezoelectric, SPR, optical DNA biosensors are used to detect various viruses like hepatitis virus, HCMV, HIV, orthopox virus etc. and also for the diagnosis of various diseases like cancer, tuberculosis, COPD, genetic diseases (sickle cell anemia i.e. due to single point gene mutation), cystic fibrosis, diabetes etc. The methodologies of detecting such diseases using different types of DNA based biosensors and gene chips are described in this article. PCR free DNA chips, cell- genomic sensors and nanosensor are emerging tools in the field of diagnosis. Recent advances in developing such devices provide myriads of new opportunities for DNA diagnostics.

Keywords: DNA microarrays, DNA chips, fibre optics, optical DNA sensor, diagnostics.
