Detailed Technology Description

Blood-borne metastasis caused by circulating cancer cells (CTC) is the cause of 90% of cancer related deaths. It has been shown that circulating cancer cells can be detected and classified by a liquid blood biopsy. Liquid biopsy utilizes microfluidics and imaging as a way to detect single CTCs from dense whole blood. Unfortunately, these current microfluidic biopsy techniques lack the sensitivity to detect CTCs in whole blood due to non-selective cell sorting nature of these methods. Researchers at the University of California have developed a robust sensitive lab-on-a-chip platform to detect CTCs through a combined microfluidics and label-free approach via fluorescence lifetime imaging microscopy (FLIM). FLIM is a non-invasive methodology that can differentiate innate biological fluorescent absorbers based on the time it takes for the absorber’s fluorescence brightness to fall. A FLIM-Phasor plot that contains all fluorescent lifetime(s) of a sample can provide a straight forward visualization of the different biochemical compounds and their chemical state in the sample. Utilizing such a FLIM-Phasor plot has shown clear differentiation between different cancer cells providing greater diagnostic information regarding the isolated CTCs.
