We present a method that performs negative enrichment in two steps from 2 ml of whole blood in a total assay processing time of 60 min. This negative enrichment method employs upstream immunomagnetic depletion to deplete CDpositive WBCs followed by a microfabricated filter membrane to perform chemical-free RBC depletion and target cells isolation. We also successfully recovered circulating tumor cells from 15 cancer patient samples.

The number of receptors expressed by cells plays an important role in controlling cell signaling events, thus determining its behaviour, state and fate. Current methods of quantifying receptors on cells are either laborious or do not Current methods of quantifying receptors on cells are either laborious or do not maintain the cells in their native form. Here, a method integrating highly sensitive bioluminescence, high precision microfluidics and small footprint of lensfree optics is developed mathemaitcal quantify cell surface receptors.

This method is safe to use, less matyematical, and faster than the conventional radiolabelling emthods near field scanning methods. It is also more sensitive than fluorescence based assays and is ideal for high throughput screening.
