Label-free biosensing for every stage of biomolecular research

From early research to advanced development, get reproducable biomolecular binding data without the complexity of traditional instruments.
The data quality is excellent and highly encouraging. The analytical performance is highly impressive, particularly considering the complexity of the PD-1/PD-L1 interaction studies we do.

From sample to signal
Built around flexible assay setup

The inQuiQ connects flexible sample handling, photonic detection, and real-time data output in a workflow designed for practical label-free biosensing.

0 1

Sample

Start with the material your lab already has. Purified or crude, filtered through 0.22 µm.


  • Proteins, antibodies, and peptides
  • Small molecules and DNA
  • Serum, plasma, and lysate
  • EVs and LNPs
0 2

Flexible 4-Channel Setup

Four channels allow users to flexibly run different assays, conditions, references, or experiments.

Photonics Detection

Binding at the surface shifts the local refractive index. The photonic chip reads that shift and turns it into a signal.

Why labs are looking beyond traditional biosensing methods like SPR & BLI

Surface plasmon resonance
  • Scaling requires a new instrument
  • Bulky instrument with at least 1 to 24-hour equilibration

  • Gold chip surface not ideal for complex matrix assays
  • Instrument, service, and specialist cost stacks up
inQuiQ integrated photonics
  • Modular platform with high-throughput pathway
  • 4-channel flow-cell on your own bench, ready in 5 minutes
  • Strong small molecule and broad application fit
  • Low cost of ownership with photonic techonology
Biolayer interferometry
  • Dip sensor sensitivity limits weak and small analytes
  • Upgrading throughput requires a new instrument
  • Only parallel samples, with a single "channel"

  • Single-use tips make cost per sample climb

Tell us about your binding questions.

Some teams want to see the instrument run. Others need the numbers first, or a conversation about whether the assay will work at all.
