We describe an autonomous DNA nanorobot capable of transporting molecular payloads to cells, sensing cell surface inputs for conditional, triggered activation, and reconfiguring its structure for payload delivery. The device can be loaded with a variety of materials in a highly organized fashion and is controlled by an aptamer-encoded logic gate, enabling it to respond to a wide array of cues. ...

Motion is a common phenomenon in biological processes. Major advances have been made in designing various self-propelled micromachines that harvest different types of energies into mechanical movement to achieve biomedicine and biological applications. Inspired by fascinating self-organization motion of natural creatures, the swarming or assembly of synthetic micro/nanomachines (often referred ...

Objective (s): Nanotechnology has gained importance in recent years due to its ability in the enhancement of materials properties and other specifications such as antimicrobial properties. Nano-sized materials have been applied in various fields of dentistry. Nanotechnology can be employed in orthodontics to enhance the quality of treatment. In the current study, a comprehensive review is carri...

Nano technology has vast applications such as microscopic robots or travel inside the body to deliver drug or do micro surgery. One major requirement to carry out such activity is power. Here in my paper, I have studied the possible sources of power supply from within the body and supply from outside the body, their merits and demerits. I have studied the various factors and different situation...

Ultrasound is an attractive modality for controlling micro/nanorobots due to penetrating deep into tissue, not being affected by the opaque nature of animal bodies, and generating a broad range forces. However, ultrasound microrobots have poor navigation capabilities number parameters involved in its motion make it extremely challenging human controller accurately predict manually correct micro...

Magnetic micro/nanorobots (MagRobots) with unparalleled advantages, including remote mobility, high reconfigurability and programmability, lack of fuel requirement, versatility, can be manipulated under a magnetic field, which has attracted considerable research attention in the biomedicine. materials, as key components MagRobots, generate reactive oxygen species (ROS) vivo to induce tissue/org...

This study is a review or survey on the use of nanobots in medicine. Designing and creating tiny machines, particularly robotic field nanorobotics. Any "smart" structure that able to act, sense, signal, process information, think, manipulate, exhibit swarm behaviour at nanoscale nanorobot (10-9m). More specifically, term "nanorobotics" (as opposed "micro robotics") refers engineering nanotechno...

This research examines or surveys the use of nanobots in medical field. Nanorobotics is science and technology developing fabricating small machines, particularly robotic machines. A nanorobot any "smart" structure with nanoscale actuation, sensing, signalling, information processing, intelligence, manipulation, swarm behaviour (10-9m). The phrase "nanorobotics" contrasts term "microrobotics" r...

Nanotechnology is a cutting-edge concept that evolving manifolds in various fields of science and medicine by no means exceptional to dentistry. popularly known as the ‘science small’ deals with particles size 1-10nm. Methods like top-down or bottom-up approaches are used manufacturing nanoparticles nanorobots, catering needs medical diagnostics therapeutics. Nanorobotics advances through minia...

The fast evolution of medical micro- and nanorobots in the endeavor to perform non-invasive operations living organisms has boosted use diverse imaging techniques last years. Among those techniques, photoacoustic (PAI), considered a functional technique, shown be promising for visualization micromotors deep tissue with high spatiotemporal resolution as it possesses molecular specificity optical...
