Antibody-independent micro filtration biochip for the diagnosis of lung cancer This research project focuses on the detection of circulating tumour cells (CTCs) using an antibody-independent microfluidic filtration system to filter peripheral blood and trap CTCs. To date, research results have been presented at the British Toracic Oncology Group Meeting 2011, the World Circulating Tumour Cells Conference 2011 and the IASLC symposium in London.+
