Small. 2015 Jun 10;11(22):2607-13. doi: 10.1002/smll.201402650. Epub 2015 Jan 29.


A micrometer-sized affinity bead (red) is (i) taken up into a cell by phagocytosis, (ii) photochemically released from phagosomes, (iii) optically trapped by the cell, and (iv) isolated by cell lysis for subsequent analysis of captured intracellular analyte (green).

Keywords: affinity beads; microfluidics; optical tweezers; photochemical internalization; single-cell analysis.
