The smallest medical robot is 120 nm, and was achieved by Soutik Betal (India), Ruyan Guo, and Amar Singh Bhalla (both USA) at the University of Texas at San Antonio, in San Antonio, Texas, USA, on 10 November 2016.

The smallest medical robot measuring a maximum length of 120 nm was demonstrated on November 10th, 2016, by a team of electrical and materials engineering researchers at the University of Texas at San Antonio, San Antonio, Texas, United States.

The movement and the functions of this series of incredibly small robots are remotely controlled by magnetic field. These nanorobots have the capabilities to generate on-demand and highly localized electrical pulses that propel their movements. They can interact with biological cells and perform functionalities such as cell targeting, permeation, patterning and transport in bio-cellular environment.

This series of nanorobots was created by Soutik Betal (India), Ruyan Guo and Amar Bhalla (both USA) and to be used to advance the research in, for example, cell-based therapy that treats cancers or Alzheimer’s diseases.
