An approach to sequence DNA without tagging

Research output: Contribution to journalConference articlepeer-review


A concept to sequence DNA without tagging the molecule is developed. The fabrication process is compatible with current microelectronics and (emerging) soft-material fabrication technologies, allowing the method to be integrable with MEMS and lab-on-a-chip devices. The preliminary results indicate sensitivity in the nano-gram regime for 100 micron-square pixels. The technology can be extended to perform combinatorial analysis with on-line measurement in real-time during the hybridization process.
