In traditional nanopore sequencing, biological nanopores (usually proteins) are embedded in a lipid bilayer to form a pore through which DNA strands pass, and the electrical signals are used to read the sequence. Hybrid nanopores incorporate synthetic or solid-state elements in conjunction with the biological nanopores to address some of the limitations of purely biological nanopore sequencing methods.

Advantages of Hybrid Nanopores over Other Nanopore Sequencing Methods:

Enhanced Stability:

Biological nanopores can be sensitive to environmental conditions and may have limited stability. Hybrid nanopores leverage solid-state materials, which can provide increased robustness and stability during sequencing experiments.

Controlled Pore Size:

Solid-state components in hybrid nanopores allow for more precise control over the pore size. This control is crucial for achieving higher sequencing accuracy and reducing the likelihood of base-calling errors.

Improved Signal-to-Noise Ratio:

Combining biological and solid-state elements can result in better signal-to-noise ratios. The synthetic components can enhance the detection of signals, making it easier to discern the sequence information from the electrical signals.

Longer Read Lengths:

Hybrid nanopores may offer the potential for longer read lengths compared to some purely biological nanopores. This is beneficial for applications such as de novo genome sequencing and the assembly of complex genomic regions.

Customization and Tunability:

Hybrid nanopores allow for the engineering of specific features, such as adjusting the size of the nanopore or incorporating additional functionalities. This flexibility enables the customization of nanopores for different sequencing applications.

Reduced Sensitivity to Sample Contaminants:

Solid-state elements in hybrid nanopores can be less susceptible to certain sample contaminants that may interfere with the performance of biological nanopores. This can contribute to more reliable and consistent sequencing results.

Parallelization:

The integration of solid-state components can facilitate the creation of arrays or platforms with multiple nanopores, allowing for parallel sequencing of multiple DNA strands. This increases throughput and accelerates the sequencing process.

Compatibility with Nanoelectronics:

Hybrid nanopores can be designed to integrate with nanoelectronic devices, enabling seamless integration into existing electronic platforms for data analysis and processing.

While hybrid nanopores offer several advantages, it’s important to note that nanopore sequencing technologies are continually evolving, and various methods have their unique strengths and limitations. Researchers are actively exploring ways to optimize hybrid nanopores and improve their performance for a wide range of applications in genomics, diagnostics, and personalized medicine.
