News Finding: "When you get a flat tire, you will likely just replace it instead of buying a new car.
Paper Finding: When the invader concentration was less than 2 nM (1×), it preferentially triggered the faster reaction and the concentration of the product from the slower reaction remained low (Fig.
News Context: The true benefit lies in enabling bioengineers to build more complicated and sophisticated nano machines that can be reconfigured at will. "When you get a flat tire, you will likely just replace it instead of buying a new car. Such a manual repair is not possible for nanoscale machines," said co-author Grigory Tikhomirov.
Paper Context: We expect the overall rate of the faster reaction to be approximately 18 times that of the slower reaction ( Supplementary Fig. When the invader concentration was less than 2 nM (1×), it preferentially triggered the faster reaction and the concentration of the product from the slower reaction remained low (Fig. However, when the invader concentration exceeded 1×, the faster reaction was quickly saturated and the excess invader was available to also trigger the slower reaction.
