From: Rapid detection of vaccinia virus using biofunctionalized fiber-optic ball-tip biosensors
Detection of VV at different concentrations through a ball resonator functionalized with rabbit serum antibodies. (a) S-polarization spectrum, measured for each concentration of VV from 103 to 108 PFU and for for the reference value in PBS. (b) Inset on the highlighted green region (1580–1590 nm) containing the most prominent spectral feature, i.e. the spectral peak around 1583 nm. (c) Timeline of VV detection, reporting the response of the sensor over time, for the reference level (PBS) and by increasing the virus concentration from 103 to 108 PFU.
