Solid-Phase Cytometry (SPC) is a cutting-edge technique that enables the direct detection and quantification on a membrane. Unlike traditional cytometry methods, which rely on cells flowing through a detector, SPC combines imaging, fluorescence staining, and the immobilization of cells on a track-etched membrane to deliver ultra-sensitive and highly selective microbial detection.
To date, it remains the only technology capable of detecting as few as a single cell in filterable samples.
Earlier generations of SPC, while demonstrating high sensitivity, were also labor-intensive, requiring multiple manual handling steps and complex workflows. These limitations not only reduced throughput and increased the risk of cross-contamination, but also hindered widespread adoption, particularly in routine or high-throughput settings.
At Redberry, we’ve reimagined SPC by removing the barriers that once limited its use. Through the integration of innovative optics, advanced viability staining chemistry, and powerful AI-based image analysis within a fully automated system, we’ve developed a next-generation platform capable of reliably detecting single cells—even in large and complex samples. With Redberry, SPC becomes faster, simpler, and truly accessible—ready for real-world applications at scale.

At the heart of Redberry technology lies our patented approach to SPC, built around three key innovations:
By leveraging staining kinetics, Redberry SPC eliminates over 99% of non-specific signals from inert or autofluorescent particles. This significantly improves the accuracy of microbial counts, especially in complex, particulate-rich or cell-based samples, where conventional techniques often fail
