Recent advancements in microfluidic-based biosensors for detection of genes and proteins: Applications and techniques

This article has tried to provide an overview of the most sophisticated microfluidic biosensors for identifying nucleic acids and proteins at the site of treatment. Microfluidics, which also automates sample preparation and reduces processing time and reagent consumption, enables the analysis of small sample quantities. Microfluidics and biosensor technologies collaborate to provide diagnostics at the point of care with high throughput analysis, portability, and disposability. The high sensitivity and selectivity requirements, false response errors, and integration with other essential modules are some of the challenges posed by this merger. The broad categories of protein-based and DNA-based biosensor technology are covered in this review. Also, recent advancements in coupling the biosensors to microfluidics, the main challenges and potential solutions in deploying microfluidic biosensors for point-of-care diagnostics, and the most recent developments in these areas have been discussed.
