Detailed explanation-1: -Researchers at the Indian Institute of Technology here have developed a handheld Surface Enhanced Raman Spectroscopy (SERS)-based platform for early diagnosis of dengue and also gives dengue test results within one hour (rapid diagnosis).

Detailed explanation-2: -The Trioplex rRT-PCR Assays are used when Dengue, Chikungunya, and Zika are apparent [97]. This allows a laboratory to test for all three viruses simultaneously. The FDA did a study to show the effectiveness of the CDC DENV RT-PCR Multiplex Assay [98].

Detailed explanation-3: -Symptoms usually show up four to seven days after being bitten by an infected mosquito, and may include: Sudden high fever (104°F or higher)

Detailed explanation-4: -For patients with suspected dengue virus disease, NAATs are the preferred method of laboratory diagnosis. NAATs should be performed on serum specimens collected 7 days or less after symptom onset.

Detailed explanation-5: -Surface-enhanced Raman spectroscopy (SERS) is all about amplifying Raman signals from molecules, by several orders of magnitude [8]. SERS is a technique where molecules undergo much higher scattering efficiencies when adsorbed on metal colloidal nanoparticles or rough metal surfaces.
