Can Nanotechnology Be Injected?

In this article we will be considering “Can Nanotechnology Be Injected?”

What Are Nanobots?

  • According to Wikipedia Nanoid robotics, or for short, nanorobotics or nanobotics, is an emerging technology field creating machines or robots whose components are at or near the scale of a nanomete.
  • Nanobots are robots made of nanomaterials that can carry out tasks. Scientists hope to use nanobots in medicine to kill cancer cells, deliver drugs to target tissues, and improve vaccines. Nanobots are also used in research as DNA probes, cell imaging materials, and cell-specific delivery vehicles.

Benefits Of Nanobots

The major advantages that nanobots are;

  • Durability, as they could last for years.
  • The operation time would also be much lower because their displacements are smaller.
  • Hence reduced material cost
  • Accessibility to previously unreachable areas are the motivating factors.

Disadvantages Of Nanobots

However, nanobots face some limitations, including;

  • High design and development costs
  • High complexity and difficulties with the interface.
  • Due to the viscous nature of blood at the nanoscale, it is nearly impossible for the drug-carrying nanorobots to pass through blood vessels

What is Nanotechnology?

  • Nanotechnology is the term given to those areas of science and engineering where phenomena that take place at dimensions in the nanometer scale are utilized in the design, characterization, production and application of materials, structures, devices and systems.
  • According to Wikipedia nanotechnology, also shortened to nanotech, is the use of matter on an atomic, molecular, and supramolecular scale for industrial purposes.
The American physicist and Nobel Prize laureate Richard Feynman introduce the concept of nanotechnology in 1959. During the annual meeting of the American Physical Society, Feynman presented a lecture entitled “There’s Plenty of Room at the Bottom” at the California Institute of Technology (Caltech).

Types Of Nanotechnology

There are four major types of nanomaterials that are currently used namely;

  • Carbon-based nanomaterials
  • Metal-based nanomaterials
  • Dendrimers nanomaterials
  • Nanocomposites nanomaterials

The Four Generations Of Nanotechnology

  • Passive Nano-structures.
  • Active Nano-structures.
  • Systems of Nano-systems.
  • Molecular Nano-systems.

Simple Applications Of Nanotechnology

  • Electronics: The use of nanotechnology allows electronics to be faster, smaller, and more portable. It increases the power of electronic devices, improves the density of memory chips, and helps reduce power consumption and the size of transistors used in integrated circuits
  • Energy: Nanotechnology can be used to improve renewable energy sources; for example, wind energy efficiency can be improved by using light, more strength nanomaterials for rotor blades. In bioenergy using Nano-based precision farming to optimize crop used to produce biofuels.
  • Biomedicine: The chemical and physical properties of the surface of these materials allow their use in diagnosis, biosensing and bioimaging devices, drug delivery systems, and bone substitute implants
  • Environment: The most important applications of nanotechnology in the environment include using nanofilters, nanoparticles, nanophotocatalyst, nanoclays, and carbon nanotubes in water treatment and using bionanosensors for quick detection of water pollution.
  • Food: Nanomaterials used for food packaging provide many benefits such as improved mechanical barriers, detection of microbial contamination and potentially enhanced bioavailability of nutrients.
  • Textile: Textiles can be nanoengineered to have specific functions including hydrophobicity, antibacterial properties, conductivity, antiwrinkle properties, antistatic behavior, and light guidance and scattering.
Nanomedicine is the application of nanomaterials and devices for addressing medical problems. Nanomedicine has demonstrated great potential for enabling improved diagnosis, treatment, and monitoring of many serious illnesses, including cancer, cardiovascular and neurological disorders, HIV/AIDS, and diabetes. etc.
