Individual Foldscopes, as Dr Prakash dubs them, are printed on A4 sheets of paper (ideally polymer-coated for durability). A pattern of perforations on the sheet marks out the 'scope's components, which are colour-coded in a way intended to assist the user in the task of assembly—for the Foldscope has no written instructions to guide, or possibly frustrate, the user.
Through routine quality control testing, a researcher working with Markus Ralser, who would eventually become the lead researcher for the project, stumbled upon signs of the metabolic process where, for all intents and purposes, there shouldn't have been. Until now, much of the science community has generally agreed that Ribonucleic acid, or RNA, was the first building block of life because it produces enzymes that could catalyze complex sequences of reactions such as metabolic action. However, Ralser's lab found the end products of the metabolic process without any presence of RNA. Instead, the findings indicate that complex and life-forming reactions like these could occur spontaneously given the right, but surprisingly simple, conditions.
