How Photonic Biochips Work

Photonic biochips utilize light, not electricity, to detect biomarkers. Light travels through a spiral-shaped structure embedded in the chip, resembling a miniature optical fiber.


  • > Biorecognition: Receptor molecules on the chip’s surface selectively bind specific biomarkers from the sample.
  • > Signal Detection: Interaction between receptor molecules and biomarkers alters the properties of the light passing through the chip.
  • > Diagnostic Output: Changes in the light’s properties are detected and converted into actionable diagnostic data, such as biomarker presence or concentration.

Photonic Diagnostic Platform

Surfix’s photonic diagnostics platform lies at the core of its POC testing solutions. This user-friendly, reliable, and sensitive biosensor can detect multiple biomarkers simultaneously—an essential feature for modern healthcare.


KEY ADVANTAGES


  • > Multiplexing Capability: Detects multiple biomarkers in a single test.
  • > User-friendly: No need for a skilled lab technician.
  • > Fast: Time-to-result deduced to only 1-15 minutes.
  • > Scalable: Low unit cost with potential for mass production.
  • > Accessible: Simplifies diagnostics, bringing lab-level precision to POC settings. 

Streamlined Workflow

Surfix combines the photonic biochip and microfluidic cartridge with advanced technologies for fluidic and optical interfacing, creating a seamless diagnostic process. Once the sample is prepared for analysis, it flows to the photonic biochip for detection.


The desktop reader completes the system, offering a plug-and-play platform adaptable to various diagnostic applications depending on the biomarkers targeted.
