Assay of Thiamine in Biologic Fluids
Clinical Chemistry, 1959 Abstract A method based on the protozoan Ochromonas malhamensis has been developed for assaying thiamine in biologic fluids. It is sensitive, specific and reproducible. Results by this method agree well with other less convenient methods of thiamine assay.

Femtosecond Photonic Viral Inactivation Probed Using Solid-State Nanopores [PDF]
arXiv, 2018 We report on the detection of inactivation of virus particles using femtosecond laser radiation by measuring the conductance of a solid state nanopore designed for detecting single virus particles. Conventional methods of assaying for viral inactivation based on plaque forming assays require 24-48 hours for bacterial growth.
