SIEN-NET™: Custom capture technology


SIEN-NET is an advanced capture platform that enables rapid capture and detection of multiple targets of interest in remarkably small sample volumes. As seen in the micro-scale image on the left, SIEN-NET utilizes a unique 3-D scaffold to bind targets of interest with exceptional yield and specificity, while avoiding unwanted contamination. SIEN-NET is adaptable for single or multi-target evaluation of virtually any molecule or even cell type of interest, often surpassing sensitivities of pre-existing assays to the femto-molar range. The technology is compatible with a wide variety of downstream applications, and raw sample compatibility allows for sample prep times of less than 30 minutes.

The SIEN-NET™ advantage


SIEN-NET technology benefits from unparalleled capture and detection sensitivities, combined with minimized non-specific binding. Sample prep times are typically 30-45 minutes from raw sample to answer.

Conventional Capture Methods

  • Capture 1 target of interest
  • Low capture yield per bead
  • High non-specific binding
  • Extensive sample prep time


  • Simultaneous capture of multiple targets of interest
  • Maximum binding capacity per bead
  • 30-45 minute sample-to-result
  • Point-of-Care enabling


SIEN-NET is highly customisable to bind and extract a wide variety of cellular and molecular targets from almost any sample type.
