In a TEDx talk, Samir Iqbal explains that nanotechnology enables scientists to control material at a molecular level, leading to its use in diverse fields such as cosmetics, sunscreen, and medicine. In medicine, nanotechnology can revolutionize cancer detection and treatment through devices like nano pores, cantilevers, and quantum dots. Iqbal discusses a nanoscale membrane with micropores that can detect tumors based on chemical, mechanical, and physical behaviors, aiding in creating personalized treatments. By examining cells at the subcellular level, nanotechnology can provide a detailed understanding of the tumor, leading to effective treatments that address individual patient needs.

  • 00:00:00 n this excerpt, the speaker discusses the prevalence of nanotechnology in our everyday lives and how it has revolutionized the way we do things, from setting alarms on our phones to the frames of our bikes. He explains that the ability to work at the nano scale has come about due to microelectronics and the development of solid-state electronics, and that we now have tools to control material at this scale. This has led to the use of nanotechnology in many areas, including cosmetics and sunscreens. The speaker also notes the potential for nanotechnology to help those in poorer areas of the world.
  • 00:05:00 In this section, the speaker discusses how nanotechnology can revolutionize healthcare and cancer detection. Through the use of devices such as nano pores, cantilevers, and quantum dots, we can interface with living systems at a molecular scale and detect diseases such as cancer. Despite the toxic effects of past emissions being regulated, mortality rates due to cancer have not decreased in the last 50-60 years. Nanotechnology offers new ways to detect and treat cancer, such as separating cells based on electrical behavior, coating surfaces to capture tumor cells, and analyzing mechanical properties of cells. With the knowledge gained from the Human Genome Project, we can now identify genes and proteins and develop new methods for cancer detection and treatment.
  • 00:10:00 In this section, Samir Iqbal discusses how nanotechnology can be used in cancer detection to objectively identify whether there are tumor cells in a given sample, which could lead to a more personalized approach to treatment. He gives an example of a nanoscale membrane with a micropore that can identify tumors based on their mechanical, physical, and chemical behavior. This technology could help identify subpopulations within a tumor and lead to more precise treatments based on each individual patient’s needs or signature.
  • 00:15:00 In this section, the speaker discusses the limitations of the one-size-fits-all approach in cancer therapy and highlights the strengths of nanotechnology in addressing this issue. By examining cells at the cellular and subcellular level and analyzing their genomic and proteomic makeup, nanotechnology can provide a complete and precise understanding of the tumor, which is crucial in devising effective treatment strategies. Understanding the enemy is the first step toward defeating the enemy.
