Nanotechnology refers to the exploitation of all strange materials’ properties which are
smaller than 100nm (nanometer) with the objective of creating new useful objects. The
aforementioned work is accomplished because of the possibility of manipulating structures of
materials within the size-scale of atoms. It is in some cases termed as, Engineering within
Molecular Level. It is basically the applied science, as well as, engineerings multi-disciplinary
area which deals with extremely small components’, as well as, systems’ design and
manufacture. The small components along with systems are built within the molecular levels of
matter which are usually characterized by enormous surface areas when compared to their
volumes and their behaviors adhere to the quantum mechanics laws (Ramsden, 2011).
Nanotechnology is applied in various ways within the fields of medicine, engineering
among others. The application of nanotechnology within the medical filed is termed as
nanomedicine. Nanotechnology is applied in drug delivery. There are diverse approaches of
nanomedicine which span from the medical utilization of nanomaterials to the nanoelectric
biosensors together with probable future molecular nanotechnology applications. Nanomedical
approached within drug deliver entail the development of nanoscale molecules or simply
molecules so as to make better a certain drug’s bioavailability. Bioavailability basically refers to
the drug molecules presence wherever they are required within the body and where the
likelihood of doing the best is high. Drug delivery main focus is to maximize bioavailability not
only at certain places within the body but also over a certain time period. This is accomplished
by molecular targeting via nano-engineered devices.
The novel nano-engineered materials’ methods which are under development will
probably turn out as effective in the treatment of illnesses along with diseases such as cancer.
Besides through nanotechnology, drug delivery systems, polymer-based or lipid nanoparticles

can successfully be designed to make better the pharmaceutical, as well as, therapeutic drugs
properties (Fulekar, 2010). The drug delivery systems’ strength is considered to be their ability to
not only alter the pharmacokinetics but also bio-distribution of drugs. Nanoparticles possess
unusual properties which can be utilized in making better drug delivery. Potential nanodrugs
operate by quite specific, as well as, well understood mechanisms. One impact of
nanotechnology along with nanoscience will be the development of generally new drugs that are
not only effective but also have fewer side effects.
Nanotechnology has also brought about positive impact in computer engineering which is
the backbone of information technology. In the contemporary communication technology,
conventional analog electrical devices have been almost totally replaced by optoelectronic
devices as a result of their large band width, as well as, capacity. Perfect examples are the
photogenic crystals, together with quantum dots (Fulekar, 2010). The photonic crystals are
simply materials that have a periodic variation within the refractive index along with a lattice
constant which is fifty percent of the wavelength of the utilized light. Quantum dots are basically
nanoscaled objects that can be utilized along with other things, for the design and construction of
the lasers quantum dot. Lasers are considered to be not only cheaper but also provide high
quality beams. Besides, low energy consumption displays can be produced by the use of carbon
It has also been established that nanotechnology is set to bring about revolution within
the agricultural industry. This is due to the fact that it will bring about novel tools for treatment
of diseases through molecular means, drastic disease detection in addition to increasing the
plants ability to absorb nutrients. Moreover, smart sensors along with smart delivery systems are
set to assist the agricultural sector in combating viruses along with other crop pathogens.
