AB  - Kiton red 620 (KR620) doped polystyrene latex microspheres (PSLs) were 
      synthesized via soap-free emulsion polymerization to be utilized as a relatively 
      nontoxic, fluorescent seed material for airflow characterization experiments. 
      Poly(styrene-co-styrenesulfonate) was used as the PSL matrix to promote KR620 
      incorporation. Additionally, a bicarbonate buffer and 
      poly(diallyldimethylammonium chloride), polyD, cationic polymer were added to the 
      reaction solution to stabilize the pH and potentially influence the electrostatic 
      interactions between the PSLs and dye molecules. A design of experiments (DOE) 
      approach was used to efficiently investigate the variation of these materials. 
      Using a 4-factor, 2-level response surface design with a center point, a series 
      of experiments were performed to determine the dependence of these factors on 
      particle diameter, diameter size distribution, fluorescent emission intensity, 
      and KR620 retention. Using statistical analysis, the factors and factor 
      interactions that most significantly affect the outputs were identified. These 
      particles enabled velocity measurements to be made much closer to walls and 
      surfaces than previously. Based on these results, KR620-doped PSLs may be 
      utilized to simultaneously measure the velocity and mixing concentration, among 
      other airflow parameters, in complex flows.
