In-Vitro Diagnostics & POC

Plasmonic ELISA™

LamdaGen’s diagnostic Plasmonic ELISA enables central laboratory-grade
quantitation for high-sensitivity immunoassays. Plasmonic ELISAs can facilitate
diagnostic detection limits into the femtomolar range, nearly four orders of
magnitude lower than that of conventional ELISA.

LamdaGen’s nano-plasmonic LSPR films can be grown on virtually any solid support including:

  • Polymers
  • Flexible Membranes
  • Glass
  • Cellulose
  • Stainless Steel
  • Others…

The Company’s plasmonic sensors are easily manufactured in any size or shape.  They are typically grown as individual or multi-paneled circular spots ranging in diameter from 300 microns up to 2.5 millimeters each – depending on functional density needs.

When coupling flexible sizing with the ability to configure sensors into any shape and upon any solid support – Plasmonic ELISA becomes an exceedingly adaptable and powerful platform for next generation diagnostic integration.

Additionally, the platform offers significant multiplexing capabilities.  The multi-panel LSPR sensors can be configured to meet almost any throughput need – from multi-parallel simultaneous systems to combined multiplexed series formats that can be actively timed or sequenced over periods of minutes, hours or even days – depending on system and end user needs.

Troponin I (cTnI) Quantification
A sensitive biomarker of myocardial injury


Troponin I (cTnI):

  • Central to the earlier diagnosis of myocardial infarction (MI)
  • Prediction of outcome: death/MI and further risk

Plasmonic ELISA™ Platform Assay:

  • Detect TnI at 0.64 pg/mL
  • Significantly more sensitive than commercial ELISA kits
  • Precise and easy quantitation


LamdaGen’s nano-based LSPR Plasmonic ELISA typically exceeds conventional ELSIA LOD by more than  four orders.
