Simple lab-on-chip approach with time-based detection

Exploring the potential for using inexpensive natural reagents extracted from plants to teach chemical analysis

“…Several books, articles and presentations (Wang, 2002;He et al, 2007;Horoszewski et al, 2007;Armenta et al, 2008;Garcia-Reyes et al, 2009;Koel and Kaljurand, 2010) have been published that review the various ways of conducting green analytical chemistry, mostly with an emphasis on the development of automatic instrumentation, sensor technology, and methodologies that offer high sample throughput with micro-/nano-level sample and reagent consumption. The low cost aspects of analytical chemistry teaching are also covered in the area of adaptation of low cost materials for construction of analytical devices (Grudpan et al, 2009;Jacobson et al, 2011;Kradtap Hartwell et al, 2011). A few reports mentioned the use of natural reagents including plant, animal, and microbial sources in place of synthetic reagents for chemical analysis (Armenta et al, 2008;Grudpan et al, 2010;Jacobson et al, 2011).…”
