This document discusses various applications of nanotechnology. It begins by defining nanotechnology as the design and manipulation of structures less than 100 nanometers in size. It then discusses uses of nanotechnology in medicine such as targeted drug delivery and disease detection. Nanotechnology is also being applied in textiles to create protective clothing and impart durability. In food science, nanotechnology helps increase shelf-life and carrier systems deliver additives without changing food properties.

2. NANOTECHNOLOGY /NANOSCIENCE
• Nanotechnology is the cluster of techniques
involved in design, synthesis, characterization
and application of structures, materials,
devices and systems by manipulating shape
and size at nanometer scale.
• It is the branch of technology that deals
with making structures that are less than
100 nanometres long.
• Nanoscience refers to the handling of
materials, systems and devices at atomic,
molecular and macromolecular level.
• Professor Norio Taniguchi coined the
term nanotechnology in 1974.
• Nanometer is one billionth of a meter.

3. Nanoparticles as Nanosensors:
• Nanobiosensors are developed to detect microbes in processing of
food material, plants and for the quantification of food ingredients,
alarming customers and suppliers over the food safety status.
• It acts as an indicator which that reacts to environmental changes in
microbial contamination, storage rooms and in products degradation .
• . Optical immunosensors have extremely complex detection systems.
In these immunosensors, thin nano-films or sensor chips are loaded
with specific antibodies, antigens, or protein molecules.
• These chips produce signals on detection of target molecules.
• e.g. E. coli.

4. NANOTECHNOLOGY IN MEDICINE:
• Nanoparticles as nanosensors [30]. in medicine and physiology, through a high grade of useful precision.
Therefore, they provide a degree of integration among technology and the biological system.
• Manipulation of drugs, active compounds and devices at nanometer scale, allows to control and alter the
essential properties and bioactivity of the ingredients. Thus, they allow to control the solubility of drugs,
controlled release, and targeted drug delivery [34]. Different applications of nano materials and nano-
medicine comprise fluorescent biological labels, detection of amino acids, lipids and proteins, drug delivery,
and other macromolecules, pathogen detection, probing of DNA structure, tumour identification and
detection, and tissue engineering, MRI contrast enhancement and purification of biological molecule.
Nanomachinery is crucial in designing of nano-medicine. Meticulous control and manipulation of
nanomachinery in cellular environment results in better thoughtful of the cellular mechanistic studies in
living cells. It also aids to develop innovative technologies towards the early finding and therapy of several
diseases. Development of nano-medicine and advancement in biomedical engineering, provides a podium
that effect nanoscale imaging, elucidating the molecular mechanisms inside the living cells [36]. Molecular
imaging has become a very influential device to imagine molecular events underlying ailment state, often
prior to its appearance. Adjunct of nanotechnology with molecular imaging offers a multipurpose stage for
designing nanoprobes with remarkable potential and enhanced specificity, sensitivity and signalling
capabilities to use as biomarkers in human diseases [37]. Nanoparticle renders molecular imaging by
increased signal sensitivity, improved 3D resolution and capacity to spread data in biological systems at
subcellular level. Simple magnetic nanoparticles serve as magnetic resonance imaging contrast

5. NANOTECHNOLOGY IN FABRICS:
• Nanotechnology has recently brought immense
improvement in the textile industry. The unique properties
of nanomaterials are applied in an efficient manner by
textile engineers and scientists, and it has gained
enormous attention in the commercial market for their
huge economic benefits.
• Nanomaterials in textiles have proved to be immensely
valuable for the manufacturing of protective garments for
workers involved in emergency services such as military
personnel, firefighters and medical workers.
• Synthesized nanoparticles are incorporated into the fibers
or textiles.
• Nanoparticles are also applied as a coating on the surface
of the finished product. There are also different coating
techniques such as sol-gel, plasma polymerization and
layer-by-layer that are used in the application of
nanoparticles onto textile fibers.
• These techniques can enhance durability and are also
capable of making the fabric resistant to extreme weather
conditions. The composition of nanocoating materials,
such as surfactants and carrier medium, can alter the
surface texture of fabrics.
• Nanofibers can also enhance the tensile strength of
composite fibers.

6. NANOTECHNOLOGY IN FOOD SCIENCE:
• Nanotechnology increasing the shelf-life of
different kinds of food materials and also helps in
bringing down the extent of wastage of food due
to microbial infestation.
• The nanostructured food ingredients are being
developed in such a way it offer improved taste,
texture, and consistency.
• Nowadays, nanocarriers are being utilized as
delivery systems to carry food additives in food
products without disturbing their basic
morphology.
• Nanotechnology is being applied in the formation
of encapsulation, emulsions, biopolymer
matrices,etc. offers efficient delivery systems.
