Review Questions

• How does nanomedicine enhance drug delivery systems compared to traditional methods?
  • Nanomedicine enhances drug delivery systems by utilizing nanoparticles that can specifically target diseased cells while minimizing exposure to healthy tissues. This targeted approach improves the therapeutic effect of medications and reduces side effects. Traditional drug delivery methods often lack this level of precision, resulting in systemic distribution that can affect non-target tissues.
• Discuss the role of biosensors in nanomedicine and their impact on disease diagnosis.
  • Biosensors play a vital role in nanomedicine by providing sensitive and specific detection of biomolecules associated with various diseases. By integrating nanotechnology into biosensor design, these devices can achieve higher accuracy and faster results than conventional diagnostic tools. The impact on disease diagnosis is significant as it allows for earlier detection and better monitoring of disease progression, which can lead to timely interventions.
• Evaluate the potential ethical concerns associated with the development and application of nanomedicine in clinical settings.
  • The development and application of nanomedicine raise several ethical concerns, including issues related to safety, long-term effects of nanoparticles in the human body, and equitable access to advanced treatments. There is also concern about potential environmental impacts from manufacturing and disposal of nanoscale materials. Addressing these ethical considerations is crucial as nanomedicine moves towards clinical implementation to ensure patient safety and social equity in healthcare access.
