We can take advantage of the wide electromagnetic spectrum to do wonde rful things that are more vital to our lives. For example\, microwave abla tion of cancer tumor is already in wide use\, and microwave remote monitor ing of vital signs is becoming more important as the population ages. This talk will focus on a biomedical use of microwave at the single-cell level . At low power\, microwave can readily penetrate a cell membrane to interr ogate what is inside a cell\, without cooking it or otherwise hurting it. It is currently the fastest\, most compact\, and least costly way to tell whether a cell is alive or dead. On the other hand\, at higher power but l ower frequency\, the electromagnetic signal can interact strongly with the cell membrane to drill temporary holes of nanometer size. The nanopores a llow drugs to diffuse into the cell and\, based on the reaction of the cel l\, individualized medicine can be developed and drug development can be s ped up in general. Conversely\, the nanopores allow strands of DNA molecul es to be pulled out of the cell without killing it\, which can speed up ge netic engineering. Lastly\, by changing both the power and frequency of th e signal\, we can have either positive or negative dielectrophoresis effec ts\, which we have used to coerce a live cell to the examination table of Dr. Microwave\, then usher it out after examination. These interesting use s of microwave and the resulted fundamental knowledge about biological cel ls will be explored in the talk.\n\nSpeaker(s): Prof. James Hwang\, \n\nVi rtual: https://events.vtools.ieee.org/m/239462 LOCATION:Virtual: https://events.vtools.ieee.org/m/239462 ORGANIZER:gelefth@ece.utoronto.ca SEQUENCE:3 SUMMARY:Microwaving a Biological Cell Alive ‒ Broadband Label-free Noninv asive Electrical Characterization of a Live Cell URL;VALUE=URI:https://events.vtools.ieee.org/m/239462 X-ALT-DESC:Description: <br /><p>Microwave is not just for cooking\, smart cars\, or mobile phones.
