The study on gold nanoparticle market covers the analysis of the leading geographies such as North America, Europe, Asia-Pacific, and RoW for the period of 2017 to 2025.
In India, nanobiotechnology is providing an incipient insight in employing Indian greeneries, which is a great source of various plant products used in Ayurveda for the synthesis of eco-friendly and non-hazardous nanoparticles. (17) Particles smaller than 100 nm are considered as nanoparticles, which have unique particle size along with advanced physical, chemical, and biochemical properties.

The scientists used several techniques, including dynamic light scattering, Fourier transform infrared spectroscopy, scanning electron microscopy and fluorescence spectroscopy, to characterize the physicochemical properties of the pectin-coated nanoparticles. Their stability was evaluated under simulated gastrointestinal conditions with digestive enzymes.
The resistive force is the mechanical energy cost required for the membrane to wrap around the nanoparticle. Until now, bioengineers only considered the driving force and designed nanoparticles to optimize the chemical interactions, a targeting strategy called 'chemotargeting.'
Titanium dioxide (Ti[O.sub.2]) nanoparticles have been shown to have antitumor effects, and inflammatory properties on mammalian cells through hydrogen peroxide ([H.sub.2][O.sub.2]) and hydroxyl free-radical production.
The nanoparticles appeared to be crystallized, and spherical in shape (Figure 1(a)) and TEM analysis revealed nanoparticles have an average diameter of 100 nm to 300 nm (Figure 1(b)).
He added that detection of the narcotics (heroin, cocaine and morphine) takes 5 minutes, noting that the nanoparticles change color from red to blue in case of drug contamination.
By using natural extract of Aspalathus Linearis crystalline perovskite ZnSnO3 nanoclusters, NiO, Pd and pdO nanoparticles are biosynthesized [15,16].
The deposition states of the nanoparticles were observed by transmission electron microscopy (TEM).
Nowadays, varieties of nanoparticles with well-defined chemical composition, size and morphology have been synthesised by different methods and their applications in many innovative technological areas have been explored (Yu et al., 2016; Khademi-Azandehi and Moghaddam, 2015).
