Figure 1. NINA-SUD device.

Figure 1

(A) A cross-sectional diagram of the NINA-SUD device. Removable foam insulation lid (a) allows insertion of 3– 100uL PCR tubes (b) into the device. An exothermic chemical reaction fuel pouch (d) delivers heat to palmitic acid PCM (c), buffering temperature to amplification specification. The reaction by-product steam is channeled into a condensing chamber (f). The PCR tube holder and support structure is made from rapid-prototyped plastic (e). (B) A photograph of the NINA-SUD device before and after initiation of the exothermic chemical reaction, along with the PCR tubes post-reaction. From left to right, the PCR tubes contain a sample, positive control, and negative control.
