PhotomisSys logo Our devices can be standalone or integrated into other systems such as optical microscopes, fluorescence and Raman systems. Being miniature these devices can be positioned under a microscope or a spectrometer to probe both concentration, refractive index, fluorescence, Raman, surface shape or other spectroscopic signals. The present version of the PhotonicSys SPR system can record sensograms with detection limit down to 10-6 refractive index units (RIU) in a user friendly graphical interface (see below). The device has a size of 4.5"x4.5"x8.5" and a weight of 1.9 kg.
Our plasmonic substrates vary depending on the type of the sensing required and maybe sold separately.

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.

SensiQ SensiQ Technologies offers a full range of Surface Plasmon Resonance instruments. "SensiQ® Discovery" is an entry-level 2 channel manual instrument intended for low-throughput applications. The "SensiQ" is a 2-channel semi-automated instrument with full temperature control, suitable for both affinity and kinetics measurements. "SensiQ Pioneer" is a fully automated and highly sensitive 3 channel capable of analyzing hundreds of samples per day using 96 and 384 well plates.

The latest addition is the SensiQ® Pioneer FE (Fragment Edition) is the new flagship SPR system and includes key features for fragment screening applications. The Pioneer FE is particularly suited to meet this challenge by providing rapid affinity data (KD) from primary screens alone and by enabling prompt identification of fragment candidate actives. Using a combination of dynamic injection SPR (diSPR®) and actives selection software, Pioneer FE provides a significant leap in real-time, label-free identification and characterization of fragment actives in screening campaigns.

Each instrument package includes full Control and Data analysis software packages. SensiQ offers a full line of affordable surface chemistries, allowing a diverse range of biomolecules to be analyzed, including small molecules below 95 Da.

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).

HoribaScientificThe 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.

The SPRi-PlexIITM (photo) is a temperature-controlled semi-automated device equipped with a computer-controlled internal fluidic system. 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.

BiacorelogoThe 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.
