Introduction

Double-stranded (DS) DNA is the major form of genetic material in most organisms. Double-stranded DNA consists of two polynucleotide chains whose nitrogenous bases are connected by hydrogen bonds. Within this arrangement, each strand mirrors the other as a result of the anti-parallel orientation of the sugar-phosphate backbones, as well as the complementary nature of the A-T and C-G base pairing.

Principle

Atomic fluorescence spectroscopy (AFS) is the emission of radiation energy in the UV-visible region from gas-phase atoms that have been excited to higher energy levels by absorption of radiant energy. Usually, a flame is used to obtain the atom in a gaseous state. It is a radiative emission process that proceeds from the lowest singlet (S1) to the singlet ground state(S0).

Applications

Atomic Fluorescence Spectrometry (AFS) is an analytical technique that is primarily used to detect and quantify metals. It is an exceptionally sensitive technique that relies on exploiting the distinctive fluorescent spectra of each specific metal.
