Next-generation sequencing (NGS), synthetic biology (SynBio), and innovative drug discovery techniques are essential for scientific research and development. These advancements have not only expanded our understanding of critical scientific processes but also facilitated groundbreaking developments in medicine, biotechnology, and environmental science. However, the complexity of assay development for these fields poses unique challenges, from streamlining NGS assays to ensuring accuracy in drug discovery and harnessing the potential of SynBio for practical applications.
Here, we delve into the intricacies of developing and validating assays across these fields, highlighting the pivotal role of emerging technologies and strategic methodologies in streamlining the process and enhancing the reliability and effectiveness of research outcomes.
NGS represents a pivotal advancement in DNA and RNA sequencing technologies, offering rapid, high-throughput, and cost-effective sequencing capabilities1. This technology enables the sequencing of millions of fragments simultaneously, providing insights into genetic variations and patterns critical for scientific discovery, diagnostics, and personalized medicine2–4. However, researchers face significant challenges in the development of robust NGS assays, including inefficient library preparation, low signal-to-noise ratios, and difficulties in achieving consistent results5–7.
Strategies to overcome these challenges include optimizing experimental designs, implementing rigorous quality control measures, and employing liquid handling automation7,8. Automated liquid handling, such as DISPENDIX's I.DOT Non-Contact Dispenser, streamlines NGS workflows by minimizing manual errors and variability in pipetting tasks, thus enhancing assay reliability and reproducibility (Fig. 1)9,10.

Developing new drugs is a complex and resource-intensive process11,12, and robust assay development and validation are critical for supporting the identification of promising therapeutic candidates. Assays, such as enzyme-linked immunosorbent assay (ELISA), enzyme activity assays, and cell viability assays, are utilized at various stages of drug discovery to evaluate compound libraries, characterize candidates, and optimize compounds based on their effects on cell health13–15.
Challenges in assay development include managing false positives/negatives, assay variability, and non-specific interactions, which can be mitigated through strategic design and validation practices16–18.
Emerging technologies, including microfluidic devices, biosensors, artificial intelligence, and automated liquid handling, play a significant role in enhancing assay development and validation19. These technologies, including the I.DOT Non-Contact Dispenser, improve assay throughput, precision, and reproducibility while reducing manual errors and sample volumes, thus streamlining drug discovery assays for better efficiency and accuracy.
