Here’s a comprehensive (48-page) review of DNA extraction methods developed for point-of-need DNA-based testing that could be useful for DNA testing practitioners, students of PCR, fieldwork researchers, and anyone interested in DNA extraction chemistry. 👇 The authors, Lee et al. (2023), review methods suitable for use outside of conventional laboratories, ranging from quick and dirty extractions to affordable and easy-to-use extraction testing devices for mass distribution, such as lab-on-a-chip devices. They also dive into the chemistry and processes behind each extraction option with referenced examples, comprehensive tables, and some great illustrations of the different methods. So this is a great learning/teaching/lookup reference even if all of your work is lab-based. Importantly, the authors examine recent DNA extraction methods devices in the context of the World Health Organisation’s REASSURED criteria for point-of-need testing, and assess their usefulness for users within this framework.
