The Challenge

Poly‑Dtech develops lanthanide‑based fluorescent nanoparticles to support immunoassays for drug discovery, biomarker screening, and rapid diagnostics. As these technologies progressed toward customer‑ready solutions, the team required detection methods that deliver high sensitivity and reproducibility while supporting workflows that translate reliably from internal development to customer laboratories.

For TR‑FRET and multiplex immunoassays, Poly‑Dtech needed to develop europium‑based nanoparticles under identical assay conditions used by end users. Differences in detection performance could impact assay robustness, reproducibility, and transfer, particularly for partners operating in regulated or high‑throughput environments.

At the same time, Poly‑Dtech’s lateral flow research extended beyond traditional visual or colorimetric readouts. The team required quantitative, sensitive detection capable of delivering reliable results within minutes to support rapid diagnostic development for time‑critical applications.

“As our TR-FRET and lateral flow assays moved toward broader adoption, it became essential to develop and validate them under the same detection conditions used by our customers. Any gap in sensitivity or workflow consistency could affect reproducibility and successful assay transfer.”
— The Poly-Dtech team

The Solution

To address these requirements, Poly‑Dtech implemented a detection platform capable of supporting multiple assay formats while remaining aligned with customer workflows. In addition to sensitivity, the team needed a system that could support TR‑FRET, multiplex immunoassays, and lateral flow research without introducing variability as assays moved from development toward broader deployment.

The SpectraMax iD5e reader supports time‑resolved fluorescence measurements required for TR‑FRET assays, enabling Poly‑Dtech to develop and validate its NoW‑Dtech™ and Multi‑Dtech™ immunoassays under the same conditions used by customers. This alignment supports reproducibility and helps reduce risk during assay transfer.

The TR‑FRET option also supports characterization of europium‑based nanoparticles, including Bright‑Dtech™ 614 – Eu (Red), for drug discovery and biomarker screening workflows. For lateral flow research, the ScanLater™ option enables quantitative measurements directly on lateral flow strips, supporting rapid, data‑driven evaluation of diagnostic assays.

Combined with SoftMax® Pro Software, the platform provides a consistent, user‑friendly workflow that supports advanced R&D and customer‑ready assay validation, helping Poly‑Dtech move efficiently from development into real‑world deployment.

“Using the SpectraMax iD5e reader, we could develop and evaluate TR‑FRET and lateral flow assays on a single platform that reflects real customer workflows. This gave us confidence that performance seen during development would translate consistently into customer laboratories.”

The Results

With the SpectraMax® iD5e Multi‑Mode Microplate Reader, Poly‑Dtech strengthened its ability to develop high‑performance, customer‑ready TR‑FRET and multiplex immunoassays with greater confidence, efficiency, and scalability. The iD5e gave Poly-Dtech a single platform to support high‑sensitivity TR‑FRET development and quantitative lateral flow detection, enabling reproducible, customer‑ready assays from day one.

By enabling development and validation under customer‑identical conditions, the iD5e platform improved assay reproducibility and reduced risk during downstream transfer. Poly‑Dtech leveraged this capability to advance next‑generation TR‑FRET kits (NoW‑Dtech™ and Multi‑Dtech™) for key applications including cytokine detection, Tag assays, and cAMP signalling, supporting drug discovery and biomarker screening workflows used by biopharma and IVD partners.

In lateral flow research, the ScanLater™ option extended Poly‑Dtech’s capabilities beyond traditional visual readouts, enabling quantitative, highly sensitive detection directly on the strip. This approach delivers reliable results in approximately 20 minutes, accelerating the development of advanced rapid diagnostic tests for prostate cancer and emerging applications in cardiac disease and other time‑critical medical settings.

Together, these capabilities reinforce Poly‑Dtech’s position as a technology partner enabling next‑generation immunoassays, while allowing the team to innovate faster, lower development risk, and deliver solutions that integrate seamlessly into customer workflows.

“The SpectraMax iD5e reader combines exceptional sensitivity with the flexibility we need to innovate across both TR‑FRET and lateral flow assays. It allows us to develop and validate our immunoassays under the same conditions our customers use, giving us confidence in obtaining reproducible results and a seamless transfer from our lab to theirs.”
