This article presents the optical diagnosis of dengue virus infection
in human blood sera through Raman spectroscopy. Raman
spectral peak at 750, 850, 1032, 1306, 1333, 1355, 1580, 1603
and 1660 cm−1 appeared only in dengue infected samples. The
Raman line at 750 cm−1 is themost prominent peak labeled forADP,
releases to extra-cellular media, as a result of cells rupturing due
to dengue virus infection. The results obtained are quite promising,
regarding the investigation of biochemical changes associated
with the dengue virus infection. The research work in our laboratory
is still in progress striving for the development of an efficient
tool that might help in the early disease detection, which is still a
desired and challenging task.
