Jack Andraka shares his personal motivation for researching pancreatic cancer after a close family friend passed away from the disease. He discovered that current detection methods are outdated, expensive, inaccurate, and often diagnose the cancer too late. This experience sparked his determination to find a better solution.
Andraka explains the difficulty of detecting cancer proteins in the bloodstream. Through extensive online research (and with 'teenage optimism'), he identified a protein called mesothelin, found at high levels in the early stages of pancreatic, ovarian, and lung cancers. His 'epiphany moment' came in high school biology class, where he connected the concepts of carbon nanotubes and antibodies to create a potential detection method.
He describes his innovative idea: combining antibodies specific to mesothelin with a network of carbon nanotubes on a strip of paper. This sensor would change electrical conductivity in the presence of the cancer protein, allowing for rapid and inexpensive detection. The process, while oversimplified in his explanation, involved significant optimization and many failed attempts.
Andraka recounts the struggle to find a lab and the numerous rejections he faced before Dr. Anirban Maitra at Johns Hopkins University gave him a chance. Despite his initial lack of lab experience and many mistakes (including contaminating and burning cell cultures), he persevered. His persistence led to a small paper sensor that is significantly faster, cheaper, more sensitive, and accurate than existing methods, capable of detecting cancer at its earliest, most survivable stages.
The developed sensor is a versatile platform that can be adapted to detect many other diseases by changing the antibodies used. However, Andraka then shifts to a major societal issue: paywalls on scientific journals. He spent over $1,000 to access necessary research papers due to exorbitant fees, highlighting how these paywalls hinder scientific advancement, especially for those without institutional funding.
Andraka argues that scientific paywalls create an 'aristocracy of knowledge,' where access to critical information is determined by wealth. He cites Harvard University's inability to afford journal subscriptions as an example of the problem's severity. This system discriminates against individuals and institutions with fewer resources, leaving billions of people without any access to scientific knowledge.
He passionately advocates for a 'knowledge democracy,' where scientific information is freely accessible to everyone, regardless of their location or economic status. Andraka believes that knowledge is the great equalizer and a basic human right, not a commodity. He concludes by stating that if a 15-year-old could innovate in cancer detection, imagine what collective advancements could be made if everyone had equal access to knowledge.
