Device to diagnose dengue within an hour

Question 1

name of device ? by whom?

Answer 1

Surface Enhanced Raman Spectroscopy (SERS)

By IIT Delhi

Question 2

why

Answer 2

for early diagnosis of dengue and also gives dengue test results within one hour (rapid diagnosis).

-Conventional Reverse Transcriptase Polymerase Chain Reaction (RT-PCR) is a time-taking process

Question 3

What is SERS?

Answer 3

technique that enhances Raman scattering by molecules adsorbed on rough metal surfaces or by nanostructures such as plasmonic-magnetic silica nanotubes.

Question 4

What is Raman effect?

Answer 4

when a stream of light passes through a liquid, a fraction of the light scattered by the liquid is of a different colour.

Question 5

Difference between Rayleigh scattering and Raman scattering.

Answer 5

Rayleigh : form of an elastic scattering of light or any other electromagnetic radiation

Raman : form of inelastic scattering of light or any other electromagnetic radiation.

Question 6

What is Raman Spectroscopy?

Answer 6

Raman spectroscopy is an analytical technique where scattered light is used to measure the vibrational energy modes of a sample.-> Mhnje jya goshtichi vibrational energy mojayachi asel tichya through light pass karayacha
