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. Stay tuned for further groundbreaking developments in this domain.

Biosensing in Drug Discovery

Biosensing in Drug Discovery

In life science research and drug discovery, biosensing technology is a pivotal innovation. This blog dives into the expansive potential of biosensing, particularly emphasizing the groundbreaking impact of label-free biosensing. We’ll also explore how multiplexed biosensors enable the detection of multiple interactions within the same sample, thereby transforming high-throughput screening.

What is Biosensing?

Biosensing involves detecting and measuring biological molecules via sophisticated biosensors. These devices combine biological recognition elements (like enzymes or antibodies) with transducers (like electrodes or optical systems) to convert biological interactions into quantifiable signals. Biosensing’s diverse applications range from clinical diagnostics and environmental monitoring to groundbreaking drug development.

What is Label-Free Biosensing?

Traditional biosensing methods often require labels (fluorescent or radioactive) for molecular identification. However, label-free biosensing changes the game by directly detecting biomolecular interactions, eliminating the need for labels. This approach preserves the natural behavior of biomolecules, offering more accurate insights.

Applications of Label-Free Biosensing in Drug Discovery

Label-free biosensing significantly influences life science research and drug discovery. Its primary use is in analyzing biomolecules’ binding kinetics, which is essential in selecting antibodies for therapeutic or diagnostic purposes. Label-free biosensors enable precise screening of antibodies, assessing their binding characteristics to specific targets.

Multiplexed Biosensors & High Throughput Screening

The advantage of multiplexity in high throughput screening is profound, especially in drug discovery. High throughput screening is used to conduct millions of chemical, genetic, or pharmacological tests rapidly. The goal is to identify active compounds, antibodies, or genes that modulate a particular biomolecular pathway. The traditional approach to screening involves testing one drug target or condition per experiment, which can be time-consuming and resource-intensive.

By employing multiplexed biosensors, it’s possible to have concurrent analysis of multiple samples against various targets. This saves time by reducing the number of individual tests needed and provides a more comprehensive understanding of how different compounds interact with multiple biological targets at once. This comprehensive data is invaluable for identifying potential effective drug candidates with minimal side effects.

For instance, a multiplexed biosensor could assess how a compound interacts with different cellular receptors, enzymes, and proteins in a single experiment. This holistic view can quickly highlight any adverse cross-reactivity of the compound, which is crucial for drug safety.
