Abstract A central goal in biology is to infer input signals from measurable readouts. Engineered biosensors are usually built to respond selectively to single inputs, so crosstalk between sensors must be removed through laborious, context-specific orthogonalization. Here we show that multiplexed concentrations can be inferred without eliminating crosstalk.

Abstract A critical goal in biology is deducing input signals from measurable readouts. Genetic circuits have successfully been designed to respond to specific analytes and produce quantifiable outputs; however, multiplexed signal processing remains challenging. This limitation is partially due to crosstalk, or sensors' non-specific responses to unintended signals. While strategies to achieve orthogonality are promising, they are time-intensive and context-dependent.
