The zapper
The zapper is the control in Molecular Reality Corporation's instrument software that sends a brief pulse of high voltage across the pore. The company's 2022 overview of its console, the demonpore 64, drew it as a "zapper stick" with a red handle that "applies a brief spike of maximum voltage", which it called useful for "characterizing pores and ionic flow", "clearing clogged smaller pores" and "electrically etching new pores".[1] In 2026 the zapper is a red-handled lever on the control panel of Maxine's Quest and a command that the live molecular stream can pass to its amplifier.[2]
Origin
The word came with the instruments. Patch-clamp amplifiers, built to record from living cells, have long carried a "zap" function: a short, large pulse that ruptures the patch of cell membrane under the tip of a glass pipette, so that the pipette can record from the whole cell. Electrophysiologists call the step break-in. The company's entry for its EDR4 amplifier notes that "Zapper (membrane break-in) and digital offset compensation are available."[3]
Uses
A pore can be blocked by a particle or a molecule that enters and does not leave. A brief rise in voltage, or a reversal, often drives it out, and the company's records list "autonomous pore declogging" among its results of December 2018.[2] The firmware of its open design, the MR1 Nanopore Reader, includes a default "unclogging" pulse of 800 millivolts lasting 250 milliseconds.[4]
Stronger fields change the membrane itself. Held long enough, a high voltage across a thin silicon nitride film can open a new pore, a method called controlled dielectric breakdown that Kwok, Briggs and Tabard-Cossa published in 2014.[5] Two years earlier the same group had shown that high electric fields can control "the size and noise of solid-state nanopores".[6] The company's Burnerphone, a research unit developed between 2021 and 2023, made pores this way.[2] The 2022 zapper stick was meant for both jobs, unclogging old pores and etching new ones.[1]
In software
Maxine's Quest draws its control panel in modeling clay. The zapper is a lever there, shown thrown down while the server reports a zap in progress, and pulling it sends the server a command called "trigger_zapper".[2] The server will not pass on a second zap within three seconds of the first.[2] On the bench, the program that drives the amplifier first asks whether the device can zap; if it cannot, it replies "Device reports zap feature unavailable", and if it can, it zaps all channels at once. When no amplifier is attached and a simulator is standing in for it, the reply is "Simulated zap triggered".[2]
A plan for game wrappers, which would dress the same data in different stories, renames the zapper in its one worked example. In the version for DogeBio, one of the company's planned games, the voltage knob becomes "Sniff intensity" and the zap button "FLUSH".[2]
