  From the famous 1918 H1N1 influenza to the present COVID-19 pandemic, the
need for improved virial detection techniques is all too apparent. The aim of
the present paper is to show that identification of individual virus particles
in clinical sample materials quickly and reliably is near at hand. First of
all, our team has developed techniques for identification of virions based on a
modular atomic force microscopy (AFM). Furthermore, Femtosecond Adaptive
Spectroscopic Techniques with Enhanced Resolution via Coherent Anti-Stokes
Raman Scattering (FASTER CARS) [1] using tip-enhanced techniques markedly
improves the sensitivity.
