Advanced optical biosensors for kinetic analysis and imaging.

EVA 2.0

Biosensor based on photonic crystal surface waves

1D Sensing & Kinetics

The EVA 2.0 is a label-free biosensor designed for precise kinetic measurements in a single point. It utilizes a laser source and angle interrogation to detect minute changes in refractive index.

Key Features:

Independent Registration: Simultaneously measures liquid Refractive Index (RI) and Adlayer Thickness using dual-polarization (s-pol and p-pol).
High Sensitivity: Uses Photonic Crystal Surface Waves (PC SM) for enhanced field confinement.
Separate Channels: Distinguishes between surface binding events and bulk liquid changes.

EVA 3.0 (Imaging)

2D Visualization & Multiplexing

The EVA 3.0 is an imaging biosensor that allows for 2D visualization of binding processes on array chips. It uses an LED source and wavelength interrogation via a color CMOS camera.

Key Features:

Multiplexing: Analyze hundreds of spots simultaneously (1000+ spots).
RGB Balancing: Unique algorithm to determine spectral shifts using a standard color camera.
High Throughput: Ideal for array-based screening and diagnostics.
Spatial Resolution: ~100 μm.
