San Diego, CA, March 13, 2017 -- The Tiny Robots Will See You Now. That’s the headline for a recent news story in IEEE Spectrum by Megan Scudellari that highlights a review paper written by UC San Diego researchers in the journal Science Robotics. This new journal is published by AAAS, the publisher of Science magazine.
The title of the actual Science Robotics review is Micro/nanorobots for biomedicine: Delivery, surgery, sensing, and detoxification. It’s authored by five researchers affiliated with the Department of NanoEngineering at the UC San Diego Jacobs School of Engineering, including professor and department chair Joseph Wang and professor Liangfang Zhang. Both professors are members of the UC San Diego Contextual Robotics Institute.

The Science Robotics article reviews recent progress and provides perspectives on the future of micro/nanorobots in biomedicine, with a focus on directed drug delivery, precision surgery, medical diagnosis and detoxification.
Thanks to recent advances in the design, fabrication, and operation, the newest micro/nanorobots have greatly enhanced power, function, and versatility, while effectively converting diverse energy sources into movement and force. Unlike their large robotic counterparts, these tiny robots can navigate through the body’s narrowest capillaries and perform procedures down to the cellular level. These tiny robots are now poised to have major impacts on disease diagnosis, treatment and prevention. Getting there will require ever closer collaborations between robotics, medical and clinical researchers, and the kinds of nanotechnology pioneers that define the Jacobs School’s NanoEngineering Department.
Some of the real-world applications of nanoengineering research at UC San Diego, including micro/nanorobots, were on display recently at a new event called NanoXpo. The industry-focused event highlighted the breadth of research in the Jacobs School’s NanoEngineering department. Read the NanoXpo story here or go directly to the NanoXpo audio story on SoundCloud.
In addition to the Science Robotics review, the publications lists from both Joe Wang’s Laboratory for Nanobioelectronics and the Liangfang Zhang’s Nanomaterials & Nanomedicine Laboratory provide many examples of cutting edge approaches to this exciting research area.
