Review Questions

• How does nanopore technology measure changes in ionic current to identify molecules?
  • Nanopore technology measures changes in ionic current as molecules like DNA or RNA pass through a nanoscale pore suspended in an electrolyte solution. When a molecule transits the pore, it partially blocks the flow of ions, resulting in a change in current. By analyzing these fluctuations, researchers can infer the size and sequence of the molecule, allowing for detailed identification and characterization.
• Discuss the advantages of using nanopore technology for DNA sequencing compared to traditional methods.
  • Nanopore technology offers several advantages over traditional DNA sequencing methods, such as Sanger sequencing or next-generation sequencing (NGS). It allows for real-time analysis and can read longer DNA fragments without the need for amplification or fragmentation. This results in reduced time and costs associated with sequencing while enabling comprehensive genomic analysis. Furthermore, its portability means it can be utilized in diverse settings, including fieldwork and remote locations.
• Evaluate the potential impact of nanopore technology on personalized medicine and its future applications.
  • The impact of nanopore technology on personalized medicine could be transformative by providing rapid and cost-effective genomic sequencing tailored to individual patients. With its ability to analyze genetic information quickly, it could facilitate timely diagnosis and treatment decisions based on a patient's unique genetic profile. Additionally, as this technology continues to evolve, it may lead to applications in detecting disease markers, monitoring therapeutic responses, and even guiding personalized treatment plans, ultimately improving healthcare outcomes.
