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
BioNavis Ltd manufactures Multi-Parametric Surface Plasmon Resonance instruments that provide high content information on molecular binding, but also at the same time on nanolayer and nanoparticle properties. Apart from kinetic constants and affinities, thanks to a multiwavelength scanning setup, also conformation changes can be resolved using LayerSolver. PureKinetics™ (pat.pend.) allows measurements of bulk effect directly in the measurement channel providing clean sensograms without bulk artifacts even in 100% serum or 5% DMSO. The MP-SPR Navi™ instruments can be used for traditional SPR applications and moreover also in material sciences.
The applications include:
(Bio)pharmaceuticals – drug-target, drug-lipid and also drug-living cell interactions, antibody characterization, controlled drug release, nanoparticle drug delivery, small molecules, measurements in 100% serum.
Biosensors – developing assays directly on final material – cellulose for printed biosensors, metal for amperometric and potentiometric sensors, polymers for well-plates, metal nanoparticles for SERS, graphene, CNTs… with crude samples including sea water, saliva, plasma and others.
Biomaterials – MP-SPR measures molecular interactions on even 15 microns thick polymers.
Thin solid films – Barrier coating development for solar cells, antibacterial coatings, moisture barrier, gas sensors using graphene, ceramics, metals and more… measurements of thickness and refractive index down to 3.7 Ångströms (graphene monolayer).
Currently, there are four models in the MP-SPR Navi family:
The instruments come with PureKinetic feature that measures bulk effect in-line and allows for even 5% changes in DMSO concentration during run or measurements in 100% serum, providing premium quality kinetics data.
LayerSolver is a software module allowing quantification of true thickness and refractive index based on a unique scanning multiwavelength measurement.
The instruments use an elastomer-coated prism which ensures easy handling of sensors (no need for refractive index oil or gold-coated prisms) and also enables storage of the sensors for future experiments, re-use or validation ex-situ.
There is a wide range of optional flow-cells including combinations with electrochemistry, fluorescence or measurements in harsh liquids. The flow-cells can be easily exchanged with a single button push.

The 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).

SENSIA has been following an innovative process of machine development and is presently bringing into market a new fully automated, bi-channel SPR device, delivering with an unequalled sensitivity and extreme stability. This new machine is a valuable addition to the known brands because of its transportability and robustness.
The main features of the new INDICATOR machine are:
The SPR imaging platform from HORIBA Scientific-GenOptics is adding a new dimension to conventional SPR. Surface Plasmon Resonance imaging (SPRi) combines the advantages of label-free analysis to the throughput of array-based assays. Hundreds of molecular interactions can be monitored in parallel in real-time (multiplexing). Ligands are immobilized in an array format (spots matrix) and the analyte solution is passed over the whole surface of the biochip. The SPR imaging signal is retrieved as real-time kinetic curves (sensorgrams) but also as real-time images of the biochip surface displaying binding events.
The SPRi platform encompasses a complete range of solutions for biomolecular interaction experiments. It includes proprietary sensor chips (SPRi-BiochipTM and SPRi-SlidesTM), an extensive range of surface chemistries (self-assembled monolayers or Dextran-based), printing devices and SPR imaging detection systems.
SPR imaging detection systems
The SPRi-Lab+TM is a flexible and manual instrument suitable for simple operation and easy determination of real-time physico-chemical interactions. Its open format allows combining SPR measurements to other techniques such as electrochemistry or fluorescence.

It is the ideal solution for bio-assays such as antibody characterization, immunoprofiling, biomarker discovery. The system can be coupled to the SPRi-autosampler for more demanding applications requiring routine sample injections.
Direct coupling of SPR imaging to MS HORIBA Scientific is pioneering the direct coupling of SPR imaging to MS (mass spectrometry). Thanks to the open format of the SPRi-SlideTM, direct MALDI-MS spectra can be acquired from the biochip, without the need for eluting the analyte.Visit Horiba

Key Features of the PlexArrayTM HT System
BIACORE 3000 system is equipped with a continuous flow system in which four channels are coupled in series. It has an automatic sample needle to deliver buffer and sample to the sensor chip surface. The continuous flow ensures that no changes in analyte concentration occur during the measurement. By using one of the flow channels as an in-line reference, a perfect control is obtained on the same sample aliquot.
The instruments of Biacore AB use a wedge shaped light source and a diode array to measure the relative outcoming light intensities. In this way, the whole optical interface has no moving parts.
Direct binding of non-labeled components can be monitored in samples ranging from small organic compounds and peptides to eukaryotic cells. Very low analyte concentrations down to the picomolar range can be handled with confidence. Non-specific binding and protein denaturation are both minimized by the use of biocompatible materials with low surface adsorption properties.
The latest machines from Biacore are the T100 and the T200, the successor of the Biacore 3000 and the Biacore A100 aiming at medium throughput. The flow cell design is different because the sensor spot are now dynamically addressed by the flow rate. Each of the four flow cells has five spots so 20 interactions at the same time can be monitored. The Biacore X100 is a simple version of the T100 with two flow cells and wizard guided interaction methods. This machine is simple to learn and simple to use but with the power and precision of a T100.
