From: Detection of dengue using PAMAM dendrimer integrated tapered optical fiber sensor
(a) Raman spectra taken before and after the introduction of DENV II E proteins to PAMAM integrated bio-functionalized TOF and (b) FESEM image taken of PAMAM integrated bio-functionalized TOF after the introduction of DENV II E proteins with 5 kV under 10 K magnification. Thickness of the tapered region here is measured at 13.5 µm.
