AB  - As cellulose nanocrystals (CNCs) are increasing in production, establishing safe 
      workplace practices in industry will be paramount to their continued use and 
      growth. Particles other than CNCs with similar high aspect ratios have exhibited 
      toxicity on inhalation. Safeguards are needed to monitor concentrations of CNCs 
      in air in industrial and laboratory settings to protect workers. However, because 
      of their size, morphology, and chemical makeup, CNCs are difficult to 
      characterize and differentiate from other dust and cellulose products. This work 
      is focused on developing an effective method of characterizing the concentration 
      of airborne ultrafine CNCs that may deposit in the respiratory tract. CNCs were 
      tagged with rhodamine b (RhB-CNCs) for improved visualization and characterized 
      using UV-vis spectroscopy (UV-vis), transmission electron microscopy (TEM), and 
      dynamic light scattering (DLS), then aerosolized and collected via a novel method 
      using plastic impingers. Concentration of RhB-CNCs was measured using UV-vis and 
      scanning mobility particle sizer (SMPS). The plastic impinger with 3D-printed 
      nozzle collected airborne CNCs at an efficiency that improves upon commercially 
      available impingers for relevant particle sizes.
