A new eco-friendly, reusable biosensor has been developed by Indian scientists that can rapidly detect dengue viruses from blood samples and that too at an early stage. Since existing detection methods cannot identify all the four types of dengue viruses, the electrode in the biosensor was coated with a probe DNA of dengue virus and its efficiency was tested in detecting dengue viruses. It can be regenerated within five minutes and still retains its ability to show similar current response when exposed to a target DNA
Early detection has become necessary to take precautions as no vaccines for the infection are available.
