PHI and Malmö University have a long-standing collaboration, dating back to 2008. The collaboration has resulted in several peer reviewed publications and a doctoral thesis. In late 2016, the European Commission granted 2.1 million euro to GlycoImaging – a joint cancer research project to develop improved methods for clinically diagnosing cancer.
Current methods for diagnosing cancer primarily focus on the proteins associated with cancer. However, there is increasing evidence that carbohydrates play an important role in the development and progression of malignant cancer. Current methods use and rely on antibodies created by living organisms. These natural antibodies, however, are not sufficiently specific to accurately detect and image carbohydrates.
The GlycoImaging project is coordinated by Malmö University and commercialized by PHI. Additional partners are Bundesanstalt für Materialforschung und Prüfung (Germany’s federal technology research institute), Umeå, Copenhagen and Turku University.

Quantitative Phase Imaging for Label-Free Analysis of Cancer Cells – Focus on Digital Holographic MicroscopyAppl Sci (2018)Read more
Review providing a current insight into QPI (quantitative phase imaging) applied to cancer research. The authors conclude that QPI is an ideal method for studying live cell dynamics by providing data from noninvasive monitoring over arbitrary time scales. The effect of drugs on migration, proliferation, and apoptosis of cancer cells are emerging fields suitable for QPI analysis. The authors also point out that need for QPI applications in clinical cancer diagnostics and treatments is emerging.

The morphological changes observed occur before and at lower concentrations than a reduction in cell metabolic activity or viability. Three classifiers are compared and we report a best case sensitivity of 88% and specificity of 94% for classification of cells as treated/untreated.

The article provides proof of concept for using holographic microscopy combined with antibody-based microarray technology for detecting morphological changes in captured cells.
Digital Holographic Microscopy for Non-invasive Monitoring of Cell Cycle Arrest in L929 CellsPLOS ONE (2014)Read more
We show that average cell phase volume results from DHM readings are comparable to the flow cytometry findings. DHM thus provides a non-disruptive alternative to flow cytometry. The technique has the potential to develop into a fast and cost-efficient method for pre-clinical monitoring of cancer treatment efficacy.

Using a unique non-invasive labelfree cell counting method, results comparable to conventional cell counting using a haemocytometer were produced. The major advantage using HolomonitorTM M2 is the opportunity to easily access information about cell number, size, optical thickness and confluence in an automatic, non-invasive manner.
