agricultural and medicinal enzyme, and to explore the use of iodine vapors as an effective screening mechanism for the presence of naringinase (Figure 3). In an animal health- related study, Parada-Sánchez et al. used the Foldscope to support taxonomic identification of Rhipicephalus sanguin- eus ticks in the field (Figure 4). Tey found that Foldscope is indeed useful for epidemiological studies in the field and for social outreach programs aimed at raising awareness about vector-borne diseases [2].
