The true potential of SmartBioSurface® extends beyond individual slide performance, deeply embedding itself within Tethis' broader liquid biopsy workflow, particularly through its synergy with the See.d® instrument. This integrated platform is designed to standardize blood sample preparation, ensuring optimal sample quality and integrity for comprehensive multiomic liquid biopsy analysis. The See.d® instrument, in combination with the nanocoated SmartBioSurface® slides, enables automated preparation of cytological samples, allowing for the detection and characterization of rare tumor and immune cells, as well as plasma for cell-free content analysis. This "all-in-one workflow" approach, as highlighted on Tethis' website, streamlines the entire process from blood collection to single-cell analysis.

The platform’s capabilities are particularly compelling for applications like circulating tumor cell (CTC) identification and characterization. Tethis' technology supports high-sensitivity detection of CTCs, even in early-stage settings, which is crucial for non-invasive cancer management. A clinical study, TET-22-001, initiated by Tethis in April 2024 at the European Institute of Oncology in Milan, is actively assessing the See.d® platform's performance in preparing samples from metastatic breast cancer (MBC) patients. This study aims to compare liquid biopsy results with concurrent tissue biopsies, guiding the development of non-invasive diagnostic tests. The initial enrollment of two MBC patients, following successful processing of samples from twenty healthy volunteers, underscores the ongoing validation of this integrated approach.

Moreover, SmartBioSurface® slides are compatible with a wide array of analytical pathology techniques, including cytology, immunocytochemistry, immunofluorescence, and FISH (Fluorescence In Situ Hybridization). This versatility allows for both morphological and biomarker-based analysis through brightfield or fluorescence imaging. The efficient cell adhesion and preserved morphology, combined with optimal cell distribution as a monolayer, facilitate multiplexing and AI-supported digital imaging. This enables automated and efficient detection, classification, and profiling of rare cells, including the immune cell compartment. Identified cells can even be recovered through microdissection for downstream molecular analysis at a single-cell level, offering unprecedented depth of insight.

It is important to note that both SmartBioSurface® slides and the See.d® instrument are currently designated for "Research Use Only" and are not for use in diagnostic procedures. This classification means Tethis is initially targeting the vast research market, providing tools that advance scientific discovery. However, the ongoing clinical studies and the company's stated focus on integrating liquid biopsy into "clinical practice" suggest a clear long-term ambition to transition these technologies into diagnostic applications, pending regulatory approvals. This strategic positioning allows Tethis to build a strong research foundation while laying the groundwork for future clinical utility.

What is the Market Opportunity for Advanced Rare Cell Diagnostics?

The market for advanced rare cell diagnostics, particularly within the liquid biopsy space, is experiencing robust growth, driven by an increasing demand for non-invasive, high-sensitivity tools in oncology, immunology, and prenatal diagnosis. Clinical lab leaders, as reported in December 2025 by Clinical Lab Products magazine, predict 2026 will be a pivotal year where clinical laboratories move beyond merely supporting care to actively directing it, largely due to advancements in molecular and biomarker assays and the integration of AI. Tethis' SmartBioSurface® slides directly address this evolving landscape by enabling superior handling and analysis of challenging samples like circulating tumor cells (CTCs) and immune cells, which are central to these next-generation diagnostics.
