At Electro-Molecular Discovery (EMD Bio), we empower next-generation diagnostics and drug development with a full suite of optical biosensors and companion diagnostic tools. Designed for real-time detection of molecular targets and signal transduction pathways, our offerings include ratiometric sensors, quantum dot probes, and FRET-based technologies engineered for clinical and research-grade performance.
What Are Optical Biosensors ?
Optical biosensors are analytical devices that convert a biological response into an optical signal—commonly via fluorescence, luminescence, or absorbance. These sensors offer high specificity, low detection limits, and fast response times, making them ideal for point-of-care diagnostics, dr ug screening, and biomarker quantification.
Applications in Diagnostics and Therapeutics
- Ratiometric Sensing Platforms
Utilize dual-wavelength sensors to measure concentration changes independent of sample volume or probe loading. Ratiometric biosensors are ideal for intracellular calcium, pH, ROS, and ion flux monitoring.
