Alto is the world's first SPR instrument to integrate digital microfluidics (DMF) with nanotechnology-based biosensors.

DMF technology enables all fluidics to be disposable, allowing for precise handling of 2μL sample volumes, crude sample compatibility and zero fluidics maintenance. Alto's compatibility with automation for both hardware and software provides sample-in/answer-out data, industry leading throughput, and 120 hours of unattended run time.

Every aspect of Alto is designed with user-friendliness and accessibility in mind—from the flexible 16 channel design to the intuitive data analysis platform.

What is Digital Microfluidics?

DMF is a liquid-handling technology capable of accurately controlling and manipulating discrete nanoliter-sized droplets through the application of voltage on an array of electrodes.

Why DMF?

DMF fluidic handling technology removes the need for any physical pumps, valves, or tubes and replaces them with a low cost disposable cartridge, providing higher data quality and less hands-on time.

How does SPR work with DMF?

We’ve integrated our proprietary localized surface plasmon resonance (LSPR) sensors into DMF cartridges - creating 16 independently addressable channels on a single cartridge.

Advantages of using DMF-powered SPR

  • Decoupling of flow rate and sensor position from dispersion, increasing data quality
  • Up to 500X less sample volume required— get full kinetics from a 2μL sample volume
  • Decoupling of interaction time from sample volume, increasing assay flexibility
  • Automated serial dilutions—reducing human error and saving time

Alto Cartridge The first‑ever DMF‑powered SPR system

Alto Cartridges have completely revolutionized the interaction of fluidics and SPR sensors by integrating them into one disposable microwell plate.
