Abstract
A micro-electromechanical platform and array system and methods for identifying microbial species with single molecule electrical conductance measurements are provided. The electromechanical platform has a two-tier actuation mechanism with a long stroke provided by a comb drive and a fine stroke provided by an in-plane flexural actuator. The platform is capable of making contact with a single-molecule, applying a bias, measuring the current, and performing a large number of measurements for statistical analysis. The system is capable of detecting any microbial species without requiring enzymatic amplification by detecting specific RNA sequences, for example. With oligonucleotide target molecules, the conductance is extremely sensitive to the sequence so even single-nucleotide polymorphisms can be identified. The system can also discern between subspecies using the same DNA probe. The system provides reliable, efficient, and inexpensive detection and species-level identification of microorganisms in complex detecting environments.
