1. A method for sequencing a nucleic acid molecule, comprising:
- (a) providing a plurality of particles adjacent to a sensor array, wherein an individual particle of said plurality of particles is positioned adjacent to an individual sensor of said sensor array, wherein said nucleic acid molecule is attached to said individual particle and has a primer hybridized thereto;
(b) bringing said nucleic acid molecule having said primer hybridized thereto in contact with nucleotides under conditions sufficient to conduct a polymerization reaction to yield a nucleic acid strand complementary to said nucleic acid molecule;
(c) using said individual sensor to measure steady state signals indicative of impedance, charge, or conductivity change within a Debye length of said individual particle or said nucleic acid molecule, to identify individual incorporation events associated with said nucleotides during said polymerization reaction; and
(d) using said steady state signals to identify a sequence of said nucleic acid strand, thereby sequencing said nucleic acid molecule.
