Microbots deliver the goods
Microbots deliver the goods B y combining two not-so-effi cient DNA delivery systems into one, Demir Akin, Rashid Bashir (Purdue University, Indiana), and colleagues have engineered super effi cient, DNA-delivering “microbots.” Viruses, bacteria, and nanoparticles are used to deliver DNA to cells. But when used in the body, each delivery vehicle has its limitations. Nanoparticles have the advan...
متن کاملBacterial toxins deliver the goods.
Some toxins produced by bacteria are so potent that scientists have long considered putting them to good use. This became possible when their structures were determined through the combined use of molecular biology and structural biochemistry. The current status of targeted toxin technology is perhaps best illustrated by exotoxin A produced by Pseudomonas aeruginosa, a Gram-negative bacterium t...
متن کاملWhither Microbots?
In the past few years there has been a great deal of discussion about the feasibility and desirability of developing microminiature robots which could be deployed en masse to do useful tasks. We attempt to examine some of the important issues involved in such a would-be endeavor, including matters of scale and controllability. Robots require considerable computational resources to be adaptive a...
متن کاملEnsembles of millions of microbots
This paper is submitted to Invited Session: New Trends in Modular Robotics. Abstract— Taking the inevitability of micron-scale manufacturing as a starting point, we present claytronics, a modular robotics system designed to scale to millions of cooperating, sub-millimeter scale units. The goal is for the system to act as a coherent mass and thereby mimic, with high-fidelity and in 3dimensional ...
متن کاملAssessing the Dynamic Performance of Microbots in Complex Fluid Flows
The use of microbots in biomedicine is a powerful tool that has been an object of study in the last few years. In the special case of using these microdevices in the human circulatory system to remove clots or to deliver drugs, the complex nature of blood flow must be taken into account for their proper design. The dynamic performance, defined in this context as the quantification of the distur...
