A molecular switch that activates and reverses on demand.

The drug runs until it's gone.

Once a treatment enters the body, it follows its own schedule. There is no adjustment. No way to slow it down when it's causing harm. No way to hold it back until the right moment arrives. No way to respond when the situation changes.

1.8 million Americans are harmed every year by drug events that better real-time control could prevent.

Every dose is a bet placed before all the information is in.

The mechanism is new. The physics is established.

Every existing approach to controlling protein activity in the body makes a tradeoff. Chemical methods are slow and passive. Light-based approaches cannot reach deep tissue. Prior systems work once and are spent. None offer repeated, on-command control.

The physical principles we build on are validated and well understood. What we have engineered on top of them has not been done before. The result is a switch that responds to an external signal in seconds, returns to baseline when that signal is removed, and repeats on demand. Administration and activation become two separate decisions.

Give it before you're certain. Activate when you are.

The only approved clot-busting drug for stroke can't be given until brain scans confirm the stroke type. That delay eats directly into a treatment window where minutes determine whether a patient recovers or faces permanent damage.

With a platform like ours: give the drug during transport, in its inactive state. No risk. The moment the scan confirms, apply the signal. It switches on in seconds. If the situation changes, switch it off.

That's one application. The same switch is designed to work across proteins and contexts without rebuilding the underlying mechanism.
