As we journey deeper into the world of Delta Diagnostics’ groundbreaking technology, we find ourselves at the heart of integrated photonic biosensors. In this episode, we’ll unveil the inner workings of these remarkable sensors, starting with the magic of waveguides. These tiny optical pathways, akin to optical fibers on a chip, guide light through bends and across the optical landscape, forming the foundation of biosensors with unmatched precision.

The Wonders of Waveguides

Waveguides play a crucial role in integrated photonic biosensors, but often do not receive the recognition they deserve. Think of them as miniature optical fibers but confined to a tiny chip’s surface. They possess the remarkable ability to guide light, even as it twists and turns along their path. This unique feature allows them to transport light across the optical chip, where it meets its destiny as a sensor.

The Birth of Sensors

Waveguides don’t just carry light; they can also be transformed into sensors. Here’s where the magic truly begins. At the surface of the waveguide, an enchanting phenomenon occurs—the evanescent field emerges. This field extends just beyond the waveguide’s surface into the surrounding medium, whether it’s a biological sample or something else.

The Dance of Biomolecules and Light

Imagine biomolecules in your sample, floating through the evanescent field. These molecules can bind to specific receptors that have been immobilized on the waveguide’s surface. When the right biomolecules bind to these receptors, they create a local change in the refractive index—affecting the speed at which light travels along the waveguide.

Light Speed and Biomolecule Concentration

Now comes the fascinating part: this change in refractive index affects the speed at which light travels in the sensor. Delta Diagnostics’ instruments are equipped with the remarkable capability to detect even the slightest variations in this light speed. It’s like catching the subtlest ripple in a pond.

Determining Biomolecule Concentrations

Get ready for a deeper dive into the technological marvels that make integrated photonic biosensors a game-changer in the world of biosensing and diagnostics. Stay tuned for more enlightening insights and innovations!

Waveguide Magic: Unraveling Biosensors Through Phase Differences

Waveguide Magic: Unraveling Biosensors Through Phase Differences

The exploration of integrated photonic biosensors unfolds a world where light manipulates the detection of biomolecules with exceptional precision. This journey delves into the heart of waveguide configurations such as ring resonators and Mach-Zehnder interferometers, showcasing their critical role in biosensing technology. By detecting phase differences induced by changes in the refractive index, these devices open a new chapter in the precise identification of biomolecules.

The Role of Waveguide Sensors

Waveguides transform into sensors with remarkable sensitivity through configurations like ring resonators and Mach-Zehnder interferometers. These structures excel in their respective domains by manipulating light in unique ways. The interaction of biomolecules with receptors on the waveguide surface alters the local refractive index, subsequently affecting light’s speed. This intricate dance between biomolecules and light is pivotal in sensing technology, where the minutest changes are captured with finespan precision.

Interpreting Phase Differences

The phenomenon of phase differences stands at the core of waveguide biosensors’ functionality. Ring resonators employ circular waveguides to create resonant conditions for specific light wavelengths. Any alteration in the refractive index, such as those caused by biomolecule binding events, shifts the resonant condition, detectable through changes in light intensity. Similarly, Mach-Zehnder interferometers split light into two paths, with any phase changes in the sample path causing interference patterns upon recombination. These patterns, or variations in light intensity, are indicative of biomolecule interactions.

A Symphony of Light Intensity

The ultimate detection in both ring resonators and Mach-Zehnder interferometers boils down to light intensity variations at the output. These variations, stemming from biomolecule-induced phase differences, are precisely detected by instruments designed for this purpose. The quantitative measurement of biomolecules is achieved with unmatched sensitivity, underlining the efficacy of waveguide-based sensors in biosensing.


Waveguide-based sensors, through their innovative use of phase differences, have revolutionized the field of biosensing. By translating changes in the refractive index into detectable light intensity variations, they offer a powerful tool for the accurate detection of biomolecules. As we continue to unravel the potential of these devices, their impact on diagnostics and biosensing technology promises to be profound. The future episodes will delve deeper into the specifics of Delta Diagnostics’ instruments and their role in advancing biosensor capabilities, marking a significant milestone in the journey towards groundbreaking diagnostics.

Enhancing Early Kinetic Screening for Optimal Drug Candidate Selection Using Integrated Photonics

In biomedical innovation, Delta Diagnostics stands at the forefront with its pioneering use of integrated photonics in high-plex biosensing. This article provides an in-depth exploration of how this cutting-edge technology is set to transform the field of drug discovery. Delta Diagnostics’ approach facilitates high-plex detection and introduces a paradigm shift in high throughput screening, thereby revolutionizing the initial stages of drug development. A critical focus of our discussion is the role of early kinetic screening in mitigating the risk of prematurely discarding promising drug candidates.

High Throughput Screening: A Shift in Drug Discovery

At the core of Delta Diagnostics’ strategy lies the application of integrated photonics, which enables the coexistence of multiple biosensors within a compact chip. This integration is a significant stride forward for high-plex detection and advancing high throughput screening to previously unattainable levels.

Drug discovery is inherently complex and time-intensive. Historically, early stages predominantly involved affinity measurements, primarily carried out through ELISA tests. Although these tests yield valuable data, they provide only a partial view. A critical element often overlooked is the kinetics of the interactions between potential drug candidates and their targets.

(Early) Kinetic Screening

The kinetic understanding of molecular interactions is crucial in drug discovery. It encompasses more than the mere strength of a compound’s binding to its target (affinity); it also includes the speed and reversibility of this binding. Kinetic screening thus offers pivotal insights into these dynamics, granting a more nuanced comprehension of a compound’s pharmacological profile.

Conventionally, kinetic screening was relegated to the later phases of drug discovery due to technological constraints. However, Delta Diagnostics’ innovative use of integrated photonics makes early kinetic screening possible and highly efficient. The implications of this advancement are profound:

  1. Reducing Attrition: Many potential drug candidates are excluded in the discovery process because they exhibit promising affinity but fail when their kinetic properties are evaluated in subsequent stages. Early kinetic screening identifies these issues sooner, curtailing the likelihood of costly late-stage disappointments.
  2. Enhanced Candidate Selection: By incorporating kinetic considerations early in the drug discovery process, researchers can select candidates with a strong binding affinity and favourable kinetic profiles, thereby improving the chances of successful drug development.
  3. Conservation of Time and Resources: Early kinetic screening streamlines the drug discovery pathway. Researchers can swiftly pinpoint compounds with desirable kinetic properties, allowing them to allocate resources more effectively towards the most promising candidates.

Integrated photonics is on the verge of revolutionizing drug discovery by facilitating early kinetic screening. This advancement in assessing molecular interactions promises significant improvements in selecting the most suitable drug candidates, thereby reducing attrition rates. As we progress, the field anticipates more efficient and fruitful drug development processes, ultimately leading to advanced treatments and therapies for many diseases. Delta Diagnostics remains at the helm of these exciting advancements in life sciences, continually expanding the horizons of what is achievable.
