Using Nobel Nanotechnology to Disrupt Establised Industries

After becoming a Nobel Laureate in 2016, Sir Fraser Stoddart, co-founded a nano-technology corporation that takes early-stage nano-material discoveries from university research & translates them into commercial products. In this interview, Sir Stoddart discuses the serendipitous discoveries that have emerged from his laboratory.

			Novel fluorescence imaging system helps surgeons remove small ovarian tumors Ovarian cancer is usually diagnosed only after it has reached an advanced stage, with many tumors spread throughout the abdomen. Most patients undergo surgery to remove as many of these tumors as possible, but because some are so small and widespread, it is difficult to eradicate all of them.

			Carbon Nanotubes (CNTs) for Immunotherapy Delivery Carbon nanotubes (CNTs) are hollow structures made up entirely from carbon. The walls of the carbon nanotube are just one atom thick, created by rolling sheets of graphene into a long tube with aspect ratios as large as several million to one. Due to their size, CNTs have been investigated for their ability to deliver immunotherapies.

	Photonics-based tiny device could one day play key role in personalized medicine In the not-too-distant future, each of us may have a simple device - small enough for our nightstand or our pocket - that keeps us apprised of our level of health, identifies even trace amounts of undesirable biomarkers in our blood or saliva and serves as an early-warning system for diseases.

	Applications of Carbon Nanotubes (CNTs) in Regenerative Medicine Regenerative medicine refers to the use of technology to directly or indirectly regenerate or grow and replace cells, tissues, or organs. This may be achieved by stimulating the repair mechanisms that are naturally present in the body. Most recently, CNTs have been tested for regenerative medicine purposes.

	Platinum nanoparticles show selective toxicity against liver cancer cells In recent years, the number of targeted cancer drugs has continued to rise. However, conventional chemotherapeutic agents still play an important role in cancer treatment. These include platinum-based cytotoxic agents that attack and kill cancer cells. But these agents also damage healthy tissue and cause severe side effects. Researchers at ETH Zurich have now identified an approach that allows for a more selective cancer treatment with drugs of this kind.
