BDI RESEARCH PAPER FEATURES AS COVER ARTICLE IN 'ANALYST'
A BDI research paper has featured as a cover article in the most recent issue of the research journal 'Analyst'. The paper focuses on the development of a ﬂuorescent method for detecting the onset of coagulation in human plasma on microstructured lateral ﬂow platforms.
Microﬂuidic devices and microsystems have been used to develop blood coagulation monitoring devices for point of care diagnostic use. However, many of them suffer from inherent variability and imprecision, partly due to the fact that they only detect changes in bulk clotting properties and do not reﬂect the microscopic nature of blood coagulation.
This work demonstrates microstructured lateral ﬂow platforms used in combination with ﬂuorescently labelled ﬁbrinogen to detect microscopic clot formation. Plasma samples applied to platforms modiﬁed with coagulation activation reagents and ﬂuorescent ﬁbrinogen produced changes in ﬂuorescence intensity due to incorporation of the ﬂuorophore into the forming microclots.
It was found that the change in the distribution of the ﬂuorescence within the sample over time was an excellent predictor of the onset of coagulation, which could be used to determine the clotting time.
