Engineering Genetically Encoded Sensors That Do Not Require Specialized Detection Equipment
We develop genetically encoded biosensors that produce visually detectable signals without the need for specialized instrumentation. By leveraging chromoprotein circular permutation and long-stokes shift, UV-excited fluorescent proteins, we create sensor systems that convert molecular recognition events directly into colorimetric or fluorescence outputs visible under simple illumination. These designs enable low-cost, biological sensing platforms for applied biotechnology applications.
Our platform enables real-time visualization of calcium dynamics and detection of peptide epitopes using only a conventional light microscope and camera.

Visible Color Peptide Indicator — Structural Mechanism Overview
Close-up of modeled peptide-sensor interaction
The Visible-Color Indicator platform enables real-time detection of intracellular analyte dynamics through visible color shifts. The system is designed to couple analyte binding events to controlled conformational changes within an engineered sensor scaffold, producing a visible optical response without external reagents or complex instrumentation.

Energy Evaluation of Designed Csp3 Monomers in Native Tetrameric Assembly
Rosetta-based interface redesign was used to disrupt the native tetrameric assembly of Csp3 and generate a monomeric scaffold for current copper mining biosensor prototype. The monomeric form may offer improved expression, increased signal brightness, and more efficient surface display on engineered materials, allowing metal ion coordination while reporting binding saturation through a fluorescent readout.
