The advancement of science is leading humanity to a new aeon: the era of nanotechnology. In simple terms, it refers to the technology exercised on materials at molecular level (less than 100 na-nometers) (1). Foundation stone of this looming phase in dentistry was laid by Richard Feynman in 1959, a noble prize winning physicist (1). Nano-technology has brought upon exorbitant changes in all per...

UNLABELLED The power available to microscopic robots (nanorobots) that oxidize bloodstream glucose while aggregated in circumferential rings on capillary walls is evaluated with a numerical model using axial symmetry and time-averaged release of oxygen from passing red blood cells. Robots about 1 microm in size can produce up to several tens of picowatts, in steady state, if they fully use oxyg...

Wirelessly interconnected nanorobots, i.e., engineered devices of sizes ranging from one to a few hundred nanometers, are promising revolutionary diagnostic and therapeutic medical applications that could enhance the treatment of major diseases. Each nanorobot is usually designed to perform a set of basic tasks such as sensing and actuation. A dense wireless network of nano-devices, i.e., a nan...

Nanorobotics encompasses the design, fabrication, and programming of robots with overall dimensions below a few micrometers, and the programmable assembly of nanoscale objects. Nanorobots are quintessential nanoelectromechanical systems (NEMS) and raise all the important issues that must be addressed in NEMS design: sensing, actuation, control, communications, power, and interfacing across spat...

We are exploring nanoelectronic engineering areas based on low dimensional materials, including carbon nanotubes and graphene. Our primary research focus is investigating carbon nanotube and graphene architectures for field emission applications, energy harvesting and sensing. In a second effort, we are developing a high-throughput desktop nanolithography process. Lastly, we are studying nanome...

The early genesis of the concept of nanomedicine sprang from the visionary idea that tiny nanorobots and related machines could be designed, manufactured, and introduced into the human body to perform cellular repairs at the molecular level. Nanomedicine today has branched out in hundreds of different directions, each of them embodying the key insight that the ability to structure materials and...

In this chapter, the concept of vibration energy harvesting and its potential utilization as a power source for micro/nanorobots is introduced and discussed. While batteries are commonly used as power sources for electronic devices, the limited lifetime and relatively large dimensional structure of batteries constrain its applications in micro/nanodevices. On the other hand, while capacitors ha...
