Delta Life Science was founded in 2018 as a spin-off from TNO (Dutch organisation for applied scientific research). Delta's mission is to make multiplexed, label-free biosensing accessible to all. In June 2024 we launched our first instrument (inQuiQ™) aiming to improve the accessibility of label-free biosensing and accelerate life science research.
With Delta's NES technology at its core, the inQuiQ™ instrument is to set to transform the landscape of biosensing. The inQuiQ™ allows scientists to conduct highly sensitive, multiplexed analysis with ease. The inQuiQ™ offers:

• 16-plex measurements: obtain more data points from a small sample on a reusable sensor
• Complex matrices: improved measurements in serum, plasma and supernatant due to the combination of a silicon chip and polycarboxylate hydrogel
• Compact design: the use of NES technology enables sophisticated analysis taking up limitid space (30 x 40 cm) on your lab bench
• Wide range of sample volumes: supports sample volume from 25 µL to 2 mL for diverse experimental needs
• Cost-effective solution: a premium instrument at an affordable price without compromising results

Take a look at the inQuiQ™ on our website and the video of the instrument launch.

The SPR #64 is equipped with a rotatable 8-channel microfluidics therefore the instrument allows the read-out of up to 64 sensor spots simultaneously. In addition, the SPR+ detection technology ensures the wide application range, covering small molecules as well as therapeutic research. In total, up to 4 microtiter plates can be used within the autosampler unit and for long term experiments the instrument allows plate feeding with external robots. Next to the standard settings the instrument stands out by features such as Dual-Injection, Frame-Injection, two external reagent supplies as well as an 8-buffer panel, which boosts the assay development capabilities to an unachieved level.

The user interaction in front of the instrument is dramatically reduced due to the usage of a dual prism consumable. This contains a cleaning prism (glass) as well as an active prism (gold + surface chemistry). Thus, after each experiment the instrument can be cleaned automatically without any user interaction.

Throughput and Sample Handling:

• Inject 8 samples simultaneously from plates with either 96- or 384-wells
• 30k+ interactions per 24 hours
• Inject samples from plates, the reagent notch or reagent troughs
• Robotic integration for additional samples (optional)
• Integration into scheduling software via it´s API

FOx Biosystems recently launched the White FOx instrument using fiber optic SPR as sensor tool bioanalysis. The White FOx technology applies the SPR sensing principle, with our own unique twist. Using fiber optic SPR (FO-SPR), it combines the ease of use of a dip-in sensor with the precision and speed of SPR.
The White FOx instrument is a robust, low-maintenance, easy-to-use benchtop device for quantification, affinity and binding interaction studies between biomolecules. Simply load a probe rack and your sample in a plate or PCR tubes to run a hands-off, automated protocol. New protocols are easily defined, changed, and stored for re-use. The open data format allows analysis with any standard data handling software. The probes can be switched easily, allowing the detection of different target molecules with a single device. What’s more, the fiber-optic probe setup allows a fluidics-free dip-in protocol for the analysis of specific biomolecule binding in complex samples such as lysates, whole blood or large particles: No clogging, no cross contamination, no cleaning.
The White FOx is Sensitive: μM to nM for label-free detection and pM to fM detection on fast ultra-sensitive gold nanoparticle sandwich assays. It offers fast time-to-result with reduced hands-on time and is cost-effective compared to competing biosensor technologies.

The P4SPR is a unique portable, 4-channel SPR instrument that delivers high-performance measuring and monitoring data of specific targets in complex media such as drugs or disease biomarkers (e.g. antibodies, antigen, hormones) in blood serum or toxic chemicals (e.g. microorganism toxins, industrial organic compounds) in underground waters.

Also, the P4SPR's open architecture makes it easy to combine with other analytical methods such as spectroscopy, chromatography and mass spectrometry to fit your specific needs.

The Sartorius Pioneer systems can characterize a wide range of interactions with high quality kinetic data (ka, kd) and affinity measurements (KD). Although based on traditional SPR, Pioneer systems incorporate OneStep injection technology. Here a compound solution is diffused into a moving stream of buffer to create a concentration gradient during the injection. As such, a single analyte injection is sufficient to measure kinetic and affinity values accurately. In contrast to traditional fixed concentration injections (FCI), OneStep provides better resolved kinetic traces compared to square-shaped traces due to the generation of a continuous concentration gradient 3–4 orders of magnitude during the OneStep process. Pioneer systems provide rapid affinity data directly from primary screens, significantly reducing the time and cost associated with secondary screening while enabling the prompt identification of lead candidates.

Pioneer System

The Pioneer SPR systems combine the accuracy and sensitivity of traditional SPR analysis with the benefits of a robust design, simpler assay setup, shorter run times, reduced sample consumption, and higher throughput. Pioneer instruments precisely deliver analyte sample to the SPR flow cell in a continuous concentration gradient using an innovative sample dispersion and delivery system. A wide range of concentrations is covered in a single injection, eliminating the need to run multiple dilutions of sample to obtain accurate kinetic and affinity constants. The injection technology saves time and sample material, reduces the variance introduced by pipetting multiple samples and target immobilization among different channels and improves analysis of unstable targets which need to be tested quickly before all activity is lost.

Pioneer FE System

This system is ideal for screenings in fragment-based drug discovery (FBDD). Using the basics of the Pioneer, the Pioneer FE system has a higher sensitivity and incorporates NeXtStep Injection technology which diffuses two different samples against each other in a crossed sigmoidal profile. NeXtStep methods employ multiple assay formats to determine competition mechanisms or inhibition concentrations (IC50) in a single injection. There is no need for a sample dilution series as the NeXtStep gradient measures a wide concentration range encompassing all concentrations necessary for analysis.Sartorius webpage

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.
