Abstract: Much of the functionality of multi - cellular systems arises from the spatial organisation and dynamic behaviours within and between cells. Current single - cell genomic methods only provide a transcriptional “snapshot” of individual cells. The real - time analy sis and perturbation of living cells would generate a step - change in single - cell analysis. Here we describe minimally invasive nanotweezers that can be spatially controlled to extract samples from living cells with single - molecule precision. They consist o f two closely spaced electrodes with gaps as small as 10 - 20 nm, which can be used for the dielectrophoretic trapping of DNA and proteins . Aside from trapping single molecules, we also extract nucleic acids for gene expression analysis from living cells, wi thout affecting their viability. Finally, we report on the trapping, and extraction of a single mitochondrion. This work bridges the gap between single - molecule/organelle manipulation and cell biology and can ultimately enable a better understanding of liv ing cells.
