Nanopore Technology: Revolutionizing Disease Diagnosis and Real-Time Genetic Sequencing

Content

• Introduction:
  Scientists have developed a nanopore-based tool capable of diagnosing illnesses with greater speed and precision by analyzing molecular signals in real time.

• What is Nanopore Technology?

  • Refers to nano-scale holes embedded in thin membranes that detect potential changes as charged biological molecules (e.g., DNA or RNA) pass through these holes.
  • It allows direct sequencing of nucleic acids (DNA and RNA) from biological samples without complex preparation.

• How It Works:

  • Biological molecules passing through the nanopore cause changes in the electrical signal.
  • These signals are analyzed to determine the molecular structure or genetic sequence.

• Applications:

  1. Genetic Sequencing: Enables fast, real-time DNA/RNA sequencing for genetic research and clinical diagnostics.
  2. Disease Marker Detection: Detects biomarkers associated with diseases at an early stage.
  3. Cancer Diagnosis: Aids in non-invasive early diagnosis of cancer by identifying circulating tumor DNA.
  4. Infectious Disease Monitoring: Enables rapid pathogen identification, crucial for outbreak control.

• Advantages:

  • Faster, real-time diagnostics.
  • High precision with minimal sample preparation.
  • Non-invasive and cost-effective.

Nanopore technology is a promising tool for revolutionizing disease diagnosis and genetic research.
