Natural convection is a situation where there is no external driving force but there is still motion of the fluid, and the inherent forces causing such convection are temperature differences or (component) concentration differences. Natural convection can also be applied to DNA amplification. When the reagents in the sample are driven by natural convection repeatedly through three different temperature zones, the sample is likely to perform the three steps of the PCR cycle: denaturation, annealing and extension. With such a platform, a sophisticated and expensive thermal cycler is no longer required.
