Abstract—In this work Raman spectra of normal and dengue infected serum and whole blood were analyzed.
In normal whole blood and serum characteristic peaks were observed when excited at 442 and 532 nm. In den-
gue whole blood and serum all peaks found to be blue shifted with reduced Raman intensity. Dengue whole
blood and serum shows two peaks at 1614 and 1750 cm^–1 which are due to presence of Immunoglobulin anti-
bodies IgG and IgM. Whole study provides a route of information for diagnosis of dengue viral infection.
