1. A method of identifying nucleic acids of interest within single cells, comprising:
- contacting a solid surface with a plurality of cells wherein the solid surface comprises an array of identical features, wherein each identical feature comprises a library of distinct oligonucleotides, wherein each oligonucleotide comprises at least one unique molecular identifier sequence and a sequence complimentary to one of a plurality of nucleic acids of interest, wherein the surface further comprises a planar electrode of negative charge and wherein the planar electrode is positioned over the solid surface with space between the solid surface and planar electrode of negative charge;
immobilizing at least one of the cells at one of the identical features on the array on the solid surface by application of an electric field;
releasing the nucleic acids of interest from the cells;
hybridizing the oligonucleotides to the nucleic acids of interest;
releasing the hybridized nucleic acids of interest and oligonucleotides from the solid surface;
sequencing the released hybridized nucleic acids of interest and oligonucleotides to generate sequence data; and
analyzing the sequence data to identify nucleic acids of interest within the single cells.
