Raman spectroscopy of carboxylated MWNT and MWNT-DENV3E samples. a, b in two different spectral regions, the Raman signatures for the samples: DENV3E protein in black, buffer solution in green, DENV3E + nanotube mixture in red, and the pure carbon nanotubes in blue. The spectrum for the DENV3E + nanotube sample clearly demonstrates the presence of the two agents
