Applications Of NMR In Biology01:25

Applications Of NMR In Biology

Nuclear magnetic resonance (NMR) spectroscopy is a very valuable analytical technique for researchers. It has been used for more than 50 years as an analytical tool. F. Bloch and E. Purcell formulated NMR in 1946 and won the 1952 Nobel Prize in Physics  for their work. Biological macromolecules such as proteins, nucleic acids, lipids, and organic molecules including pharmaceutical compounds, can be studied using this versatile tool that exploits the magnetic properties of certain nuclei.

Area of Science:

  • Biophysics
  • Molecular Biology
  • Nanotechnology

Background:

  • Nanopore transduction detection (NTD) offers sensitive applications including SNP detection, DNA re-sequencing, protein isoform assaying, and biosensing.
  • NTD involves single-molecule biophysics, information flow engineering, and nanopore cheminformatics.
  • The NTD Nanoscope has had limited adoption due to a lack of information and device availability; Meta Logos Inc. is addressing this by developing device and kit platforms.

Purpose of the Study:

  • To provide an overview of Nanopore Transduction Detection (NTD) Nanoscope applications and implementations.
  • To describe the component-level NTD Nanoscope Kit, a reproduction of the standard NTD device.
  • To highlight the potential of NTD for sensitive and discriminative molecular analysis.

Main Methods:

  • Functionalizing a single nanopore with a channel current modulator to transduce specific binding events.
  • Developing the NTD Nanoscope Kit with test buffers and control molecules for expedited lab setup, calibration, and troubleshooting.
  • Utilizing server-interfacing for advanced signal processing support.

Main Results:

  • The NTD Nanoscope method successfully functionalizes nanopores for event transduction.
  • The NTD Nanoscope Kit includes components and protocols for easier implementation in new laboratory settings.
  • Server-interfacing is available for advanced signal processing.

Conclusions:

  • The NTD Nanoscope provides higher accuracy for SNP assaying, discovery, DNA sequencing, and RNA-seq compared to enzyme-dependent methods like PCR.
  • As a single-molecule method, NTD bypasses enzyme-related error rates.
  • The NTD Nanoscope utilizes a functionalized nanopore for molecular detection.
