self-gathering particles which can shape peptide-functionalized supra-atomic
nanostructures. The self-get together of LP molecules encourages the introduction
of peptide functionalities at exceptionally high thickness on the outside of
nanostructures, for example, vesicles, micelles and fibrils. Mostly present in bacte-
rial species, they are able to self-assemble into different structures (Kirkham et al.
2016). LPs contain higher content of carbon atom (14) in lipid tail, higher
antifungal activity and antibacterial activity. LPs such as surfactin is utilized in
synthesis of gold and silver NPs in which the LPs (surfactin) is used as a stabilizing
agent or a template which plays a key role in stabilizing of the NPs (Reddy et al.
2009).

History and Development of Nanoparticles
Almost 4500 years ago, human civilization was already using ceramic matrixes
which had natural asbestos NPs. Around 4000 years ago, Egyptians used NPs in a
synthetic process for synthesis of ~5 nm diameter PbS-NPs for hair dye. Likewise,
Egyptians only prepared and used the first synthetic pigment called ‘Egyptian Blue’
using a mixture of nanoparticle-sized quartz and glass approximately in third century
BC. Egyptians and Mesopotamians in thirteenth and fourteenth century BC cited the
beginning of metallic nanoparticle era by synthesizing metallic NPs via chemical
method for making glass using metals (Schaming and Remita 2015). In
1200–1300 BC starting from late Bronze Age, Italy found red glass which was
coloured by surface plasmon excitation of Cu-NPs. 400–100 BC period has been
reported to contain the Celtic red enamels made from Cu-NPs and cuprous oxide.
The most famous example of ancient metallic NPs usage is Roman glass work piece.
Studies show that Lycurgus cups (Roman glass cups) reported during the fourth
century was made up of Ag-Au alloy NPs in a ratio of 7:3 with an addition of
approximately 10% copper. Reporting from 5000 BC, clay minerals with less thick-
ness were used for preparation of natural NPs since antiquity.
NPs have been used without any prior knowledge up to this era without having
any ability to understand the fundamental principle inheriting nanotechnological
behaviour. The first scientific description to report nanoparticle preparation and
initiating NPs history in scientific area was given by Michael Faraday in 1857. He
reported the synthesis of colloidal Au-NP solution, revealing that optical
characteristics of Au colloids were dissimilar to their bulk counterpart. SiO2
nanoparticles are substitutes to carbon black for rubber enforcement started to be
manufactured in 1940 (Rittner and Abraham 1998). The term nanotechnology was
firstly introduced by Norio Taniguchi at the International Conference on Industrial
Production held in Tokyo in year 1974 for description of the ultra-thin processing of
material with nanometre accuracy and creation of nanosized mechanism. In 1980s,
nanotechnology got major boost by development of cluster science and invention of
scanning tunnelling microscope. This development helped in discovery of structural
assignment of carbon nanotubes in 1991. First program of nanotechnology began in
1991 in the USA funded by National Scientific Fund. In 2001, National
