Plasmetrix specializes in compact and portable plasmonic devices at affordable prices for research and education. Measuring only 15cm in length, our tiny CORGI SPR system packs a lot of options and has been specifically designed to adapt to numerous laboratory and academic uses. The basic device can be ordered with add-on configurations, such as single or double channel flow-injection cell, open cuvette with option of electrochemical-SPR analysis, or conventional petri-dish for SPR sensing directly in a cellular environment. Its versatility and ease of use make it the perfect laboratory tool: the coupling prism and fluidics are easily accessible and interchangeable, and the sensing chips are conventional thin gold layers that can be either home-made or bought. Reaching a resolution of 10-6 RIU, this device shows great performances for all typical SPR monitoring applications - binding affinities, kinetics, and biosensing. Our SpectraCube LSPR system is a complete spectrophotometer optimized for plasmonic nanoparticles applications. Its design based on imaging spectroscopy has the advantage to allow both conventional single-channel analysis for sample characterization and dual-channel mode for real time differential detection using vertical or horizontal configuration with tandem cuvettes. The device is paired with an analytics software designed to precisely detect and follow plasmonic peak position (up to 0.005 nm). The system is ideal for LSPR applications including nanoparticles size and composition characterization, biosensing, and real-time monitoring of nanoparticles functionalization.Visit Plasmetrix
Kitchener, ON, January 20, 2016: Nicoya Lifesciences, a leader in label-free molecular analysis, announced today its newest product, OpenSPR-XT - a fully automated molecular analysis instrument based on the highly successful OpenSPR instrument. OpenSPR is a revolutionary surface plasmon resonance instrument that provides powerful label-free analysis while being the most affordable and compact instrument on the market. Instead of using the traditional gold films for the sensor chip, OpenSPR utilizes highly sensitive gold nanoparticles to give detailed information on nanoscale surface interactions. OpenSPR can be used for many SPR applications including binding affinity, kinetics, detection, surface chemistry and more. It is intuitive, easy to use, and compatible with proteins, antibodies, DNA, peptides, polymers, small molecules, and more. OpenSPR’s unique design also allows it to double as a visible cuvette based spectrophotometer.Visit Nicoya Lifesciences

Each instrument package includes full Control and Data analysis software packages. Pall ForteBio offers a full line of affordable surface chemistries, allowing a diverse range of biomolecules to be analyzed, including small molecules below 95 Da.
OneStep (Taylor Dispersion Injections) adds a capillary tube just in front of the sensor and disperses the sample, making it possible to do a gradient injection over 3-4 orders of magnitude. Using the Taylor Equations (from the 1950's) it is then possible to calculate diffusion coefficients and assess aggregation. More importantly, with a derivative of the sigmoidal gradient output, strong and weak binding events are now revealed in time. This has never been accomplished using SPR in the past because the sum of two exponentials is very difficult to resolve (1), (2).

PhotonicSys Surface Plasmon Resonance Sensors:
Surface waves are waves propagating along the interface of two different media. They can be gravity waves such as at the surface between two fluids with different densities, elastic waves such as seismic waves (Rayleigh or Love waves) or electromagnetic (light waves) between two media having two different optical properties. One of the intriguing phenomena occurring at the interface of metals and dielectric media is surface plasmon resonance (SPR) wave. This wave maybe described as a collective oscillation of the free electrons Fermi gas at the metal surface. Its excitation requires light with wavelength incident at an angle such that its momentum along the interface is high enough to match that of the surface plasmon wave.
