The potential applications of DNA testing methods to combat illegal wildlife contraband (Dormontt et al., 2015; Wasser et al., 2018), determine the integrity of supply chains, (Golden & Warner, 2015) and monitor for invasive species (Dejean et al., 2012) or crop pests and pathogens (Randhawa et al., 2013) are undeniable. However, a critical barrier facing the routine use of DNA testing in supply chain management, conservation and law enforcement is the difficulty in preparing samples for DNA analysis. This process of DNA extraction-collecting samples, lysing tissue and purifying or isolating target DNA-is the most time and labour-intensive step of most DNA tests and typically requires trained laboratory personnel in a fully equipped laboratory to provide target DNA with a sufficient purity for reliable analysis (Buser et al., 2016; Fredricks et al., 2005; Wu et al., 2014). DNA analysis and test systems have advanced rapidly in recent years, providing systems that can be deployed outside the laboratory to rapidly identify genetic targets of interest through rapid isothermal amplification tests (Niemz et al., 2011; Yetisen et al., 2013) and even provide sequencing reads by identifying which bases are passing through a nanopore (Loman & Watson, 2015; Mikheyev &
